fix: address code review round 2 — 9 issues (2 critical, 3 important, 4 minor)

Critical:
- #2: Add _entry_lock in RiskManager to serialize concurrent entry (balance race)
- #3: Add startTime to get_recent_income + record _entry_time_ms (SYNC PnL fix)

Important:
- #1: Add threading.Lock + _run_api() helper for thread-safe Client access
- #4: Convert reset_daily to async with lock
- #8: Add 24h TTL to exchange_info_cache

Minor:
- #7: Remove duplicate Indicators creation in _open_position (use ATR directly)
- #11: Add input validation for LEVERAGE, MARGIN ratios, ML_THRESHOLD
- #12: Replace hardcoded corr[0]/corr[1] with dict-based dynamic access
- #14: Add fillna(0.0) to LightGBM path for NaN consistency with ONNX

+# Code Review Fixes Round 2 Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Fix 9 issues from code review re-evaluation (2 Critical, 3 Important, 4 Minor)
+
+**Architecture:** Targeted fixes across risk_manager, exchange, bot, config, ml_filter. No new files — all modifications to existing modules.
+
+**Tech Stack:** Python 3.12, asyncio, python-binance, LightGBM, ONNX Runtime
+
+---
+
+### Task 1: #2 Critical — Balance reservation lock for concurrent entry
+
+**Files:**
+- Modify: `src/risk_manager.py` — add `_entry_lock` to serialize entry flow
+- Modify: `src/bot.py:405-413` — acquire entry lock around balance read → order
+- Test: `tests/test_risk_manager.py`
+
+The simplest fix: add an asyncio.Lock in RiskManager that serializes the entire _open_position flow across all bots. This prevents two bots from reading the same balance simultaneously.
+
+- [ ] Add `_entry_lock = asyncio.Lock()` to RiskManager
+- [ ] Add `async def entry_lock(self)` context manager
+- [ ] In bot.py `_open_position`, wrap balance read + order under `async with self.risk.entry_lock()`
+- [ ] Add test for concurrent entry serialization
+- [ ] Run tests
+
+### Task 2: #3 Critical — SYNC PnL startTime + single query
+
+**Files:**
+- Modify: `src/exchange.py:166-185` — add `start_time` param to `get_recent_income`
+- Modify: `src/bot.py:75-82` — record `_entry_time` on position open
+- Modify: `src/bot.py:620-629` — pass `start_time` to income query
+- Test: `tests/test_exchange.py`
+
+- [ ] Add `_entry_time: int | None = None` to TradingBot
+- [ ] Set `_entry_time = int(time.time() * 1000)` on entry and recovery
+- [ ] Add `start_time` parameter to `get_recent_income()`
+- [ ] Use start_time in SYNC fallback
+- [ ] Add test
+- [ ] Run tests
+
+### Task 3: #1 Important — Thread-safe Client access
+
+**Files:**
+- Modify: `src/exchange.py` — add `threading.Lock` per instance
+
+- [ ] Add `self._api_lock = threading.Lock()` in `__init__`
+- [ ] Wrap all `run_in_executor` lambdas with lock acquisition
+- [ ] Add test
+- [ ] Run tests
+
+### Task 4: #4 Important — reset_daily async with lock
+
+**Files:**
+- Modify: `src/risk_manager.py:61-64` — make async + lock
+- Modify: `main.py:22` — await reset_daily
+- Test: `tests/test_risk_manager.py`
+
+- [ ] Convert `reset_daily` to async, add lock
+- [ ] Update `_daily_reset_loop` call
+- [ ] Add test
+- [ ] Run tests
+
+### Task 5: #8 Important — exchange_info cache TTL
+
+**Files:**
+- Modify: `src/exchange.py:25-34` — add TTL (24h)
+
+- [ ] Add `_exchange_info_time: float = 0.0`
+- [ ] Check TTL in `_get_exchange_info`
+- [ ] Add test
+- [ ] Run tests
+
+### Task 6: #7 Minor — Pass pre-computed indicators to _open_position
+
+**Files:**
+- Modify: `src/bot.py:392,415,736` — pass df_with_indicators
+
+- [ ] Add `df_with_indicators` parameter to `_open_position`
+- [ ] Use passed df instead of re-creating Indicators
+- [ ] Run tests
+
+### Task 7: #11 Minor — Config input validation
+
+**Files:**
+- Modify: `src/config.py:39` — add range checks
+- Test: `tests/test_config.py`
+
+- [ ] Add validation for LEVERAGE, MARGIN ratios, ML_THRESHOLD
+- [ ] Add test for invalid values
+- [ ] Run tests
+
+### Task 8: #12 Minor — Dynamic correlation symbol access
+
+**Files:**
+- Modify: `src/bot.py:196-198` — iterate dynamically
+
+- [ ] Replace hardcoded [0]/[1] with dict-based access
+- [ ] Run tests
+
+### Task 9: #14 Minor — Normalize NaN handling for LightGBM
+
+**Files:**
+- Modify: `src/ml_filter.py:144-147` — apply nan_to_num for LightGBM too
+
+- [ ] Add `np.nan_to_num` to LightGBM path
+- [ ] Run tests
