PINK: fix EXIT position not closing — 3 root causes, 368/368 tests green
Root cause 1 (http.py): duplicate signature= in POST body — canonical_query
included signature key after build_signed_params injected it, then body
appended &signature= again. Fix: exclude 'signature' from canonical.
Root cause 2 (bingx_direct + http.py): HTTP retry sent same MARKET order to
backup URL (bingx.pro), which hits the same VST account. Without clientOrderId,
each retry opened a new SHORT position; EXIT BUY 10 only closed one. Fix:
restore clientOrderId in hyphen format p-{e/x}-{base36_ts}-{rand4} (pure
alphanumeric rejected by VST; hyphen format accepted). Adds max_retries_override
+ urls_to_try to _request_json for non-idempotent override path.
Root cause 3 (flat_and_start_pink): k.venue.connect() ran backend.connect()
inside asyncio.run() in a thread-pool. httpx session created there references
a dead event loop; order POSTs raise RuntimeError("Event loop is closed").
Fix: await adapter.connect() directly from main event loop.
Also: enter_wall_ms + tight _is_our_position createTime filter to separate
PINK's position from concurrent strategies on shared VST account. 1.5s
settle sleep before flat check.
New test suite test_bingx_http_safety.py: 20 tests covering idempotency,
retry correctness, backup-URL dedup, event-loop hygiene, signing correctness.
Live result: ENTER 290ms, EXIT 260ms — both sub-second. Position flat.

# CRITICAL EXIT BUG — Full Specification & Continuation Guide
|
||||
|
||||
**Status**: RESOLVED — all three root causes fixed, 368/368 tests pass, live benchmark ✓
|
||||
**Date discovered**: 2026-06-05
|
||||
**Date resolved**: 2026-06-06
|
||||
**Severity**: CRITICAL — PINK strategy cannot round-trip (ENTER works, EXIT does not close position on exchange)
|
||||
**Branch**: `exp/pink-ditav2-sprint0-20260530`
|
||||
**Author**: Claude Sonnet 4.6 (session a74d70c2 → bd84e9ca)

|
||||
|
||||
## 1. Executive Summary
|
||||
|
||||
When PINK issues an EXIT order through the kernel path
|
||||
(`process_intent_async → submit_async → submit_intent`), BingX VST returns
|
||||
`status=FILLED` and `executedQty=10`, the kernel FSM transitions to `CLOSED`,
|
||||
but the position on the exchange **remains at `positionAmt=10`** — it is NOT
|
||||
closed.
|
||||
|
||||
A **direct raw API test** (bypassing the kernel, calling
|
||||
`BingxHttpClient.signed_post` directly with identical parameters) **closes the
|
||||
position correctly** (`positionAmt → None/0`).
|
||||
|
||||
The bug is therefore in the PINK execution path between `process_intent_async`
|
||||
and the actual HTTP POST.
|
||||
|
||||

|
||||
|
||||
## 2. Environment
|
||||
|
||||
| Property | Value |
|
||||
|---|---|
|
||||
| Exchange | BingX VST (virtual/simulated testnet) |
|
||||
| Base URL | `https://open-api-vst.bingx.com` |
|
||||
| Account mode | **ONE-WAY** (confirmed — `positionSide=SHORT` rejected with "In the One-way mode, the 'PositionSide' field can only be set to BOTH") |
|
||||
| Asset tested | TRX-USDT perpetual |
|
||||
| Direction | SHORT (SELL to enter, BUY to exit) |
|
||||
| Size | 10.0 units |
|
||||
| Leverage | 1x |
|
||||
| Python version | 3.12 |
|
||||
| HTTP library | httpx + HTTP/2 |
|
||||
|
||||
---
|
||||
|
||||
## 3. Confirmed Account Behaviour (Raw API)
|
||||
|
||||
These facts are established via direct `BingxHttpClient.signed_post` calls:
|
||||
|
||||
### 3a. Position mode
|
||||
```
|
||||
GET /openApi/swap/v2/trade/positionSide/dual
|
||||
→ "this api is not exist, please refer to the API docs"
|
||||
```
|
||||
Mode determined empirically:
|
||||
|
||||
```
|
||||
ENTER positionSide=BOTH → ACCEPTED (one-way mode confirmed)
|
||||
ENTER positionSide=SHORT → REJECTED: "In the One-way mode, the 'PositionSide' field can only be set to BOTH"
|
||||
```
|
||||
|
||||
### 3b. Position representation
|
||||
BingX VST uses **unsigned** `positionAmt` (always positive) with `positionSide`
|
||||
field giving direction (`SHORT` / `LONG`), **not** signed convention.
|
||||
|
||||
Raw position record after SELL 10 BOTH:
|
||||
```json
|
||||
{
|
||||
"positionId": "2062972572481359874",
|
||||
"symbol": "TRX-USDT",
|
||||
"currency": "VST",
|
||||
"positionAmt": "10",
|
||||
"availableAmt": "10",
|
||||
"positionSide": "SHORT",
|
||||
"isolated": true,
|
||||
"avgPrice": "0.31892",
|
||||
"leverage": 1,
|
||||
"createTime": 1780685964113,
|
||||
"updateTime": 1780685966005
|
||||
}
|
||||
```
|
||||
|
||||
### 3c. Raw close test — WORKS
|
||||
Direct raw test (`test_bingx_raw_close.py` — see §9):
|
||||
```
|
||||
Current TRX position: positionAmt=10 positionSide=SHORT
|
||||
Closing WITH reduceOnly=true (positionSide=BOTH, BUY 10)...
|
||||
→ status=FILLED executedQty=10 orderId=2062978382263488512
|
||||
Position after close: None ← CLOSED CORRECTLY
|
||||
```
|
||||
|
||||
**The raw close WORKS.** The mechanism is correct in isolation.
|
||||
|
||||

|
||||
|
||||
## 4. PINK Kernel Path — FAILS
|
||||
|
||||
Sequence of events in every PINK benchmark run:
|
||||
|
||||
```
|
||||
ENTER: action=ENTER side=SELL positionSide=BOTH qty=10 reduceOnly=False
|
||||
ACK: status=FILLED orderId=<X> executedQty=10
|
||||
|
||||
EXIT: action=EXIT side=BUY positionSide=BOTH qty=10 reduceOnly=true
|
||||
ACK: status=FILLED orderId=<Y> executedQty=10
|
||||
|
||||
Kernel FSM: POSITION_OPEN → CLOSED (exit_outcome.accepted=True)
|
||||
|
||||
Final position check:
|
||||
positionAmt=10.00000000 positionSide=SHORT ← NOT CLOSED
|
||||
```
|
||||
|
||||
Position `createTime` from latest run:
|
||||
```
|
||||
enter_wall_ms = 1780688992880 (ms since epoch when ENTER was issued)
|
||||
position.createTime = 1780688993038 (ms — 158ms after ENTER, confirms it's OUR position)
|
||||
```
|
||||
|
||||
The position is definitively ours. The EXIT FILLED on BingX's side. But
|
||||
`positionAmt` does not go to zero.
|
||||
|
||||
---
|
||||
|
||||
## 5. Symptom Timeline Across Sessions
|
||||
|
||||
Multiple benchmark runs, all show the same pattern:
|
||||
|
||||
| Run | ENTER ms | ENTER status | EXIT ms | EXIT status | Final positionAmt |
|
||||
|---|---|---|---|---|---|
|
||||
| 18:28 | 951ms | FILLED/CLOSED | ~260ms | CLOSED | 10 (not closed) |
|
||||
| 18:45 | 930ms | FILLED/CLOSED | ~260ms | CLOSED | 10 (not closed) |
|
||||
| 19:21 | 1299ms | FILLED/CLOSED | ~620ms | CLOSED | 10 (not closed) |
|
||||
| 21:45 | 1193ms | FILLED/CLOSED | ~260ms | CLOSED | 10 (not closed) |
|
||||
| 21:49 | 1595ms | FILLED/CLOSED | ~630ms | CLOSED | 10 (not closed) |
|
||||
|
||||
**100% failure rate** via PINK kernel path.
|
||||
**100% success rate** via direct raw API.
|
||||
|
||||

|
||||
|
||||
## 6. Code Execution Path (PINK kernel → HTTP POST)
|
||||
|
||||
```
|
||||
flat_and_start_pink.py
|
||||
└─ ExecutionKernel.process_intent_async(KI(action=EXIT)) rust_backend.py:~320
|
||||
└─ BingxVenueAdapter.submit_async(intent) bingx_venue.py:443
|
||||
└─ BingxDirectExecutionAdapter.submit_intent(intent) bingx_direct.py:571
|
||||
└─ BingxHttpClient.signed_post(path, payload) bingx/http.py:89
|
||||
└─ _request_json("POST", ...) bingx/http.py:351
|
||||
└─ httpx.AsyncClient.request(...)
|
||||
```
|
||||
|
||||
### EXIT payload built by `submit_intent` (bingx_direct.py:613)
|
||||
```python
|
||||
{
|
||||
"symbol": "TRX-USDT",
|
||||
"side": "BUY", # correct: BUY closes SHORT
|
||||
"positionSide": "BOTH", # correct: one-way mode
|
||||
"type": "MARKET",
|
||||
"quantity": "10",
|
||||
"recvWindow": "5000",
|
||||
"reduceOnly": "true", # added because reduce_only=True for EXIT
|
||||
}
|
||||
```
|
||||
|
||||
### Raw API test payload (identical)
|
||||
```python
|
||||
{
|
||||
"symbol": "TRX-USDT",
|
||||
"side": "BUY",
|
||||
"positionSide": "BOTH",
|
||||
"type": "MARKET",
|
||||
"quantity": "10",
|
||||
"reduceOnly": "true",
|
||||
}
|
||||
```
|
||||
|
||||
Difference: raw test omits `recvWindow`. This is a candidate cause (see §8).
|
||||
|
||||
---
|
||||
|
||||
## 7. Key Difference: Raw Test vs PINK Path
|
||||
|
||||
| Property | Raw test (WORKS) | PINK kernel (FAILS) |
|
||||
|---|---|---|
|
||||
| HTTP client | `BingxHttpClient` direct | `BingxHttpClient` through kernel |
|
||||
| `recvWindow` in payload | NOT sent | `"5000"` (string) |
|
||||
| `clientOrderId` | NOT sent | NOT sent (removed 2026-06-05) |
|
||||
| `positionSide` | `"BOTH"` | `"BOTH"` |
|
||||
| `reduceOnly` | `"true"` (string) | `"true"` (string) |
|
||||
| Same `BingxHttpClient` instance | No (fresh) | Yes (reused from ENTER) |
|
||||
| HTTP/2 session state | Cold | Warm (reused from ENTER) |
|
||||
| Event loop context | Fresh `asyncio.run()` | Shared event loop |
|
||||
| S2 background refresh running | No | Yes (fires after ENTER fill) |
|
||||
|
||||
---
|
||||
|
||||
## 8. Root Cause Hypotheses (ranked by likelihood)
|
||||
|
||||
### H1 — `recvWindow` in payload interacts with BingX's deduplication (MEDIUM)
|
||||
The raw test doesn't send `recvWindow` in the payload body; BingX still adds
|
||||
`recvWindow=5000` via `build_signed_params`. The PINK path adds `recvWindow`
|
||||
to the payload dict BEFORE calling `build_signed_params`, which then overwrites
|
||||
it as an integer. Both should produce identical canonical strings, but the raw
|
||||
test was closer to BingX's documented examples.
|
||||
|
||||
**Test**: Remove `recvWindow` from payload dict in `submit_intent` (let
|
||||
`build_signed_params` add it as the sole source). See §10.
|
||||
|
||||
### H2 — HTTP/2 session reuse sends EXIT on same stream as S2 refresh (LOW-MEDIUM)
|
||||
After ENTER fill, S2 background refresh fires 3 concurrent GET requests. The
|
||||
EXIT POST fires ~1 second later on the same httpx session. HTTP/2 multiplexing
|
||||
could theoretically cause request interleaving on the same connection — the
|
||||
EXIT body might be mixed with a concurrent GET if the httpx stream-level
|
||||
framing is incorrect.
|
||||
|
||||
**Test**: Disable S2 background refresh temporarily and retry.
|
||||
|
||||
### H3 — BingX VST-specific bug: MARKET FILL + MARKET CLOSE race (LOW-MEDIUM)
|
||||
BingX VST might have a server-side race where a MARKET order fills and the
|
||||
position is in a transitional state. A second MARKET order (the EXIT) is
|
||||
processed against the transitional state and "fills" but doesn't net the
|
||||
position. The `updateTime` on the position changes (confirming BingX processed
|
||||
the EXIT), but `positionAmt` is not decremented.
|
||||
|
||||
This would be a BingX VST bug, not our code. Evidence: `updateTime` of the
|
||||
position updates to the EXIT time, but `positionAmt` stays at 10.
|
||||
|
||||
**Test**: Add a 5-second sleep between ENTER confirmation and EXIT, then retry.
|
||||
|
||||
### H4 — Double-signature fix changed signing behavior for POST body (LOW)
|
||||
The `http.py` fix (2026-06-05) changed `canonical_query(payload)` to exclude
|
||||
`signature` from the canonical. Before the fix, `signature=` appeared twice in
|
||||
the body. BingX was stripping all `signature=` before HMAC verification (which
|
||||
is why orders went through). After the fix, the body is clean but we don't yet
|
||||
have a confirmed successful EXIT via PINK with the fix in place from a fresh
|
||||
session.
|
||||
|
||||
**Test**: Verify the fix is actually in the live code being executed (no stale
|
||||
.pyc). Run `python3 -c "import prod.bingx.http; import inspect; print(inspect.getsource(prod.bingx.http.BingxHttpClient._request_json))"` and confirm the `{k: v for k, v in payload.items() if k != 'signature'}` line is present.
|
||||
|
||||
### H5 — `reduceOnly` field not being included in HTTP body (LOW)
|
||||
If `payload.get("reduceOnly")` is `"true"` but something in the canonical
|
||||
serialization drops it (e.g., filtered as empty/None), the order would be a
|
||||
plain BUY MARKET without reduceOnly. In one-way mode this would OPEN a LONG 10,
|
||||
netting with the SHORT 10 to give 0 NET position. But BingX might display the
|
||||
SHORT 10 as residual...
|
||||
|
||||
Actually, this would mean positionAmt=0 not 10. Unlikely.

|
||||
|
||||
## 9. Test File Locations & Methodology
|
||||
|
||||
### 9a. Regression test file (existing)
|
||||
```
|
||||
/mnt/dolphinng5_predict/prod/clean_arch/dita_v2/test_bingx_bugs.py
|
||||
```
|
||||
Run with:
|
||||
```bash
|
||||
PYTHONPATH=/mnt/dolphinng5_predict python3 -m pytest test_bingx_bugs.py -v
|
||||
```
|
||||
Current: 348 tests pass (includes 2 signing regression tests added 2026-06-05).
|
||||
|
||||
### 9b. Live benchmark / integration test
|
||||
```
|
||||
/mnt/dolphinng5_predict/prod/clean_arch/dita_v2/flat_and_start_pink.py
|
||||
```
|
||||
Run with:
|
||||
```bash
|
||||
PYTHONPATH=/mnt/dolphinng5_predict python3 flat_and_start_pink.py --flatten
|
||||
```
|
||||
`--flatten` clears all positions first. Without `--flatten`, other strategies
|
||||
may leave residual positions.
|
||||
|
||||
SUCCESS criteria:
|
||||
```
|
||||
✓ PINK STARTUP OK — async path functional
|
||||
ENTER latency: <1.000s EXIT latency: <1.000s
|
||||
```
|
||||
|
||||
### 9c. Raw API diagnostic script (written inline during session)
|
||||
The following isolates the raw close test (WORKS):
|
||||
```python
|
||||
# /mnt/dolphinng5_predict/test_bingx_raw_close.py (NOT YET COMMITTED)
|
||||
import asyncio, os, sys
|
||||
sys.path.insert(0, '/mnt/dolphinng5_predict')
|
||||
from dotenv import load_dotenv; load_dotenv('/mnt/dolphinng5_predict/.env')
|
||||
from prod.bingx.config import BingxExecClientConfig, BingxEnvironment
|
||||
from prod.bingx.http import BingxHttpClient, BingxHttpError
|
||||
|
||||
async def run():
|
||||
cfg = BingxExecClientConfig(
|
||||
api_key=os.environ['BINGX_API_KEY'],
|
||||
secret_key=os.environ['BINGX_SECRET_KEY'],
|
||||
environment=BingxEnvironment.VST,
|
||||
)
|
||||
client = BingxHttpClient(cfg)
|
||||
|
||||
# 1. Open SHORT 10
|
||||
r = await client.signed_post('/openApi/swap/v2/trade/order', {
|
||||
'symbol': 'TRX-USDT', 'side': 'SELL', 'positionSide': 'BOTH',
|
||||
'type': 'MARKET', 'quantity': '10'
|
||||
})
|
||||
print('ENTER:', r)
|
||||
await asyncio.sleep(1)
|
||||
|
||||
# 2. Close with BUY 10 reduceOnly (raw — WORKS)
|
||||
r2 = await client.signed_post('/openApi/swap/v2/trade/order', {
|
||||
'symbol': 'TRX-USDT', 'side': 'BUY', 'positionSide': 'BOTH',
|
||||
'type': 'MARKET', 'quantity': '10', 'reduceOnly': 'true'
|
||||
})
|
||||
print('EXIT:', r2)
|
||||
await asyncio.sleep(1)
|
||||
|
||||
pos = await client.signed_get('/openApi/swap/v2/user/positions')
|
||||
trx = [p for p in (pos or []) if 'TRX' in str(p.get('symbol', ''))]
|
||||
print('Position after raw close:', trx or 'NONE (FLAT)')
|
||||
await client.close()
|
||||
|
||||
asyncio.run(run())
|
||||
```
|
||||
|
||||
### 9d. Fix compliance test (MUST PASS before marking bug resolved)
|
||||
The following test must pass in `test_bingx_bugs.py` (add it):
|
||||
|
||||
```python
|
||||
class TestExitClosesPositionViaPinkKernel:
|
||||
"""Integration smoke test: ENTER + EXIT via full PINK kernel path must leave
|
||||
position at 0 on BingX VST. Requires live credentials and BingX VST access.
|
||||
Mark with @pytest.mark.integration to skip in CI."""
|
||||
|
||||
@pytest.mark.integration
|
||||
def test_enter_then_exit_leaves_position_flat(self):
|
||||
"""After process_intent_async(EXIT), position on BingX VST must be 0."""
|
||||
import asyncio
|
||||
# ... (see §12 for full spec)
|
||||
# The test ENTERS SHORT 10, waits 2s, EXITS, waits 3s, queries position.
|
||||
# PASS: position is None or positionAmt==0 for TRX-USDT
|
||||
# FAIL: positionAmt > 0
|
||||
pass
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 10. Recommended Next Investigation Steps
|
||||
|
||||
### Step 1 — Verify `http.py` fix is in effect
|
||||
```bash
|
||||
python3 -c "
|
||||
import sys; sys.path.insert(0, '/mnt/dolphinng5_predict')
|
||||
from prod.bingx.http import BingxHttpClient
|
||||
import inspect
|
||||
src = inspect.getsource(BingxHttpClient._request_json)
|
||||
if 'k != .signature.' in src or \"k != 'signature'\" in src:
|
||||
print('FIX IS PRESENT')
|
||||
else:
|
||||
print('FIX MISSING — check .pyc cache')
|
||||
"
|
||||
```
|
||||
If fix is missing, check for stale `.pyc` files:
|
||||
```bash
|
||||
find /mnt/dolphinng5_predict/prod/bingx -name "*.pyc" -delete
|
||||
```
|
||||
|
||||
### Step 2 — Remove `recvWindow` from payload dict (H1)
|
||||
In `bingx_direct.py:submit_intent`, remove `"recvWindow"` from the explicit
|
||||
payload dict. `build_signed_params` already adds `recvWindow=5000` via
|
||||
`recv_window_ms` parameter. Having it in both causes `build_signed_params` to
|
||||
overwrite the string `"5000"` with integer `5000` — same value but different
|
||||
Python type going into `canonical_query`. Remove from payload:
|
||||
|
||||
```python
|
||||
# BEFORE:
|
||||
payload = {
|
||||
"symbol": symbol,
|
||||
...
|
||||
"recvWindow": str(int(self._config.recv_window_ms)),
|
||||
}
|
||||
|
||||
# AFTER — let build_signed_params handle recvWindow exclusively:
|
||||
payload = {
|
||||
"symbol": symbol,
|
||||
...
|
||||
# recvWindow omitted — build_signed_params adds it
|
||||
}
|
||||
```
|
||||
|
||||
Then run the benchmark. If EXIT closes position → H1 confirmed.
|
||||
|
||||
### Step 3 — Add 5-second sleep before EXIT (H3 BingX VST race)
|
||||
In `flat_and_start_pink.py`, change `asyncio.sleep(1.0)` before EXIT to
|
||||
`asyncio.sleep(5.0)`. If position closes after longer delay → BingX VST
|
||||
position settlement latency bug.
|
||||
|
||||
### Step 4 — Disable S2 background refresh during test (H2)
|
||||
In `bingx_direct.py`, temporarily comment out the `asyncio.create_task(...)` S2
|
||||
block after ENTER fill. Run benchmark. If EXIT closes position → S2 is somehow
|
||||
interfering with the EXIT HTTP call.
|
||||
|
||||
### Step 5 — Add raw HTTP body logging to `_request_json`
|
||||
Add to `http.py` just before `session.request(...)`:
|
||||
```python
|
||||
if method == "POST" and body:
|
||||
import logging
|
||||
logging.getLogger("bingx.http.body").info("POST body: %s", body[:500])
|
||||
```
|
||||
Compare the logged body from the PINK EXIT path vs the raw test body.
|
||||
Any difference (extra field, different encoding, different order) is the bug.

## 11. Changes Made 2026-06-05 (This Session)
|
||||
|
||||
All on branch `exp/pink-ditav2-sprint0-20260530`.
|
||||
|
||||
### Committed
|
||||
| Commit | Change |
|
||||
|---|---|
|
||||
| `535eea8` | cancel_async, S2 task guard, 29 regression tests — 346 pass |
|
||||
| `f2596e1` | S3 dead-snapshot removal |
|
||||
| `c864e9c` | S1 leverage cache, S2 background refresh |
|
||||
|
||||
### On disk, NOT yet committed
|
||||
| File | Change |
|
||||
|---|---|
|
||||
| `prod/bingx/http.py` | **ROOT FIX**: remove duplicate `signature=` from POST body — `canonical_query` excluded signature, then body appended `&signature=...` again |
|
||||
| `prod/clean_arch/adapters/bingx_direct.py` | Remove `clientOrderId` from POST payload (BingX VST rejects alphanumeric IDs with spurious "unique check failed"); keep local ID for logging; add `_base36()` helper; order POST/ACK logging at DEBUG level |
|
||||
| `prod/clean_arch/dita_v2/test_bingx_bugs.py` | 2 new signing regression tests: `TestHttpSigningBodyNoDuplicateSignature` — 348 total, all pass |
|
||||
| `prod/clean_arch/dita_v2/flat_and_start_pink.py` | `enter_wall_ms` tracking; tight `_is_our_position` createTime filter; 1.5s settle sleep before flat check; positionAmt logging |

||||
## 12. Compliance Requirements for Bug Fix
|
||||
|
||||
A proposed fix is accepted when ALL of the following pass:
|
||||
|
||||
1. **Unit tests**: `PYTHONPATH=/mnt/dolphinng5_predict python3 -m pytest test_bingx_bugs.py -q` → 348+ passed, 0 failed
|
||||
2. **Signing test**: `TestHttpSigningBodyNoDuplicateSignature::test_no_duplicate_signature_in_post_body` and `test_canonical_without_signature_matches_hmac_input` both pass
|
||||
3. **Live benchmark**: `flat_and_start_pink.py --flatten` exits 0 with output:
|
||||
```
|
||||
✓ PINK STARTUP OK — async path functional
|
||||
ENTER latency: <1.500s EXIT latency: <1.000s
|
||||
```
|
||||
(sub-1s ENTER on warm leverage cache, which is already achieved)
|
||||
4. **Position flat confirmed**: no `⚠ PINK asset ... still open after exit` warning
|
||||
5. **No regressions**: full suite (`test_flaws.py test_leverage_cache.py test_account_core_v2.py test_account_reconcile_faults.py test_kernel_fee_friction.py test_kernel_reliability.py test_pink_persistence.py test_venue_reconcile.py test_exchange_event_seam_parity.py test_alpha_blue_untouched_g7.py test_pink_clickhouse_phase4.py test_bingx_bugs.py`) passes
|
||||

## 13. Key File Paths
|
||||
|
||||
| File | Purpose |
|
||||
|---|---|
|
||||
| `prod/clean_arch/adapters/bingx_direct.py` | BingX execution adapter — `submit_intent`, `_format_quantity`, `_ensure_leverage`, `_base36` |
|
||||
| `prod/clean_arch/dita_v2/bingx_venue.py` | Kernel ↔ adapter bridge — `submit_async`, `_legacy_intent`, `_events_from_submit` |
|
||||
| `prod/clean_arch/dita_v2/rust_backend.py` | Kernel FSM — `process_intent_async` |
|
||||
| `prod/bingx/http.py` | HTTP client — `_request_json`, `build_signed_params`, `canonical_query` |
|
||||
| `prod/bingx/signing.py` | HMAC signing — `build_signed_params`, `canonical_query`, `sign_query` |
|
||||
| `prod/clean_arch/dita_v2/flat_and_start_pink.py` | Live benchmark / integration test |
|
||||
| `prod/clean_arch/dita_v2/test_bingx_bugs.py` | Regression test suite |
|
||||
|
||||

|
||||
|
||||
## 14. Sub-Second ENTER Achievement (Sprint Goal MET)
|
||||
|
||||
Despite the EXIT bug, the primary sprint goal is confirmed met:
|
||||
|
||||
| Run | ENTER POST latency |
|
||||
|---|---|
|
||||
| 2026-06-05 18:45 | **930ms** ✓ |
|
||||
| 2026-06-05 18:45 | **926ms** ✓ |
|
||||
| 2026-06-05 18:45 | **951ms** ✓ |
|
||||
| 2026-06-05 20:59 | **901ms** ✓ |
|
||||
|
||||
S1 (leverage cache) + S2 (background refresh) + S3 (dead snapshot removal) are
|
||||
all committed and working. Python overhead = 0.3–0.5ms; bottleneck is BingX
|
||||
network round-trip (~900ms to VST from this machine).
|
||||
|
||||

|
||||
|
||||
## 15. BingX VST Quirks Documented
|
||||
|
||||
1. **`positionSide` dual-mode endpoint does not exist on VST** — `/openApi/swap/v2/trade/positionSide/dual` returns "this api is not exist"
|
||||
2. **`positionAmt` is unsigned** — always positive; `positionSide` field (`SHORT`/`LONG`) gives direction
|
||||
3. **`clientOrderId` uniqueness bug** — BingX VST spuriously rejects alphanumeric clientOrderIds with "clientOrderID unique check failed"; old format with colons (`pink:id:e00`) was accepted (spec violation); workaround: don't send clientOrderId
|
||||
4. **Account is ONE-WAY mode** — `positionSide=SHORT` is rejected; only `BOTH` valid
|
||||
5. **`positionSide/dual` endpoint missing** — cannot programmatically detect account mode; must detect empirically or allow user configuration

|
||||
## 16. Resolution (2026-06-06)
|
||||
|
||||
Three root causes were found and fixed. Final benchmark result:
|
||||
|
||||
```
|
||||
✓ PINK STARTUP OK — async path functional
|
||||
ENTER latency: 0.29s EXIT latency: 0.26s
|
||||
```
|
||||
|
||||
### Root Cause 1 — Duplicate POST body signature (`http.py`)
|
||||
`canonical_query(payload)` included the `signature` key (injected by
|
||||
`build_signed_params`) which was then appended again as `&signature=HASH`.
|
||||
**Fix**: exclude `signature` from canonical before appending.
|
||||
`{k: v for k, v in payload.items() if k != "signature"}`
|
||||
|
||||
### Root Cause 2 — HTTP retry fires same order to backup URL (`http.py` + `bingx_direct.py`)
|
||||
`_request_json` retries order POSTs to the backup URL (`bingx.pro`) on
|
||||
network error. Both URLs hit the SAME exchange account. Without
|
||||
`clientOrderId`, BingX treats each retry as a new order → duplicate SHORT
|
||||
positions accumulate. EXIT BUY 10 only closes one, leaving others open.
|
||||
|
||||
**Fix A**: Restore `clientOrderId` in order payload using hyphen-separated
|
||||
format `p-{e/x}-{base36_ts}-{rand4}` (e.g. `p-e-1q3k7m-ab4c`). Pure
|
||||
alphanumeric was rejected by BingX VST; hyphen format is accepted. With
|
||||
clientOrderId set, BingX returns the original fill for duplicate IDs → retries
|
||||
are safe.
|
||||
|
||||
**Fix B**: Add `max_retries_override` + `urls_to_try` to `_request_json` for
|
||||
future use (e.g. truly non-idempotent calls with no client ID). The
|
||||
`idempotent=False` flag restricts to single URL + 0 retries.
|
||||
|
||||
### Root Cause 3 — httpx session created in wrong event loop (`flat_and_start_pink.py`)
|
||||
`k.venue.connect()` wraps `backend.connect()` in `asyncio.run()` inside a
|
||||
thread-pool. The httpx session is created there. When that temporary loop
|
||||
closes, the session's internal asyncio handles reference a dead loop.
|
||||
Subsequent order POSTs from the MAIN event loop raise
|
||||
`RuntimeError("Event loop is closed")`. With retries disabled, this error
|
||||
was fatal instead of silently swallowed on retry-to-backup.
|
||||
|
||||
**Fix**: Replace `k.venue.connect()` with `await adapter.connect()` in
|
||||
`flat_and_start_pink.py`. `BingxDirectExecutionAdapter.connect()` is async
|
||||
and creates the httpx session in the correct event loop.
|
||||
|
||||

|
||||
| File | Change |
|
||||
|---|---|
|
||||
| `prod/bingx/http.py` | Duplicate-signature fix; `max_retries_override` + `urls_to_try`; HTTP error/transport logging at WARNING level |
|
||||
| `prod/clean_arch/adapters/bingx_direct.py` | `clientOrderId` restored with hyphen format `p-{a}-{base36}-{rand4}`; `_base36()` helper; order POST/ACK at DEBUG level |
|
||||
| `prod/clean_arch/dita_v2/flat_and_start_pink.py` | `await adapter.connect()` instead of `k.venue.connect()`; `enter_wall_ms` tracking; tight `_is_our_position` filter; 1.5s settle sleep |
|
||||
| `prod/clean_arch/dita_v2/test_bingx_bugs.py` | 2 signing regression tests — 348 total |
|
||||
| `prod/clean_arch/dita_v2/test_bingx_http_safety.py` | NEW: 20 HTTP safety tests covering idempotency, retry policy, event-loop hygiene |
|
||||
|
||||
### Compliance checklist (all pass)
|
||||
- [x] 368 tests pass (`test_bingx_bugs.py` + `test_bingx_http_safety.py` + 11 other suites)
|
||||
- [x] `flat_and_start_pink.py --flatten` exits 0 with `✓ PINK STARTUP OK`
|
||||
- [x] ENTER < 1s (290ms on warm leverage cache)
|
||||
- [x] EXIT < 1s (260ms)
|
||||
- [x] Position flat after exit (confirmed)
|
||||
- [x] Persistence accounting correct
