Problem:
- Users could input arbitrary initial balance when creating traders
- This didn't reflect the actual available balance in exchange account
- Could lead to incorrect position sizing and risk calculations
Solution:
- Before creating trader, query exchange API for actual balance
- Use GetBalance() from respective trader implementation:
* Binance: NewFuturesTrader + GetBalance()
* Hyperliquid: NewHyperliquidTrader + GetBalance()
* Aster: NewAsterTrader + GetBalance()
- Extract 'available_balance' or 'balance' from response
- Override user input with actual balance
- Fallback to user input if query fails
Changes:
- Added 'nofx/trader' import
- Query GetExchanges() to find matching exchange config
- Create temporary trader instance based on exchange type
- Call GetBalance() to fetch actual available balance
- Use actualBalance instead of req.InitialBalance
- Comprehensive error handling with fallback logic
Benefits:
- ✅ Ensures accurate initial balance matches exchange account
- ✅ Prevents user errors in balance input
- ✅ Improves position sizing accuracy
- ✅ Maintains data integrity between system and exchange
Example logs:
✓ 查询到交易所实际余额: 150.00 USDT (用户输入: 100.00 USDT)
⚠️ 查询交易所余额失败，使用用户输入的初始资金: connection timeout

Major fixes:
1. Trade History data loss issue
- Root cause: Open records outside analysis window caused close matching failures
- Solution: Pre-populate position state by reading 3x window of historical records
- Ensures long-term positions (>5 hours) generate correct trade records
2. P&L calculation errors
- Remove incorrect leverage multiplication from absolute P&L
- Correct calculation: Futures P&L = quantity × price difference
- Leverage only affects P&L percentage (relative to margin)
3. Other fixes
- Break-even trades (pnl=0) no longer misclassified as losses
- Perfect strategy shows Profit Factor as 999.0 instead of 0.0
- Expand analysis window from 20 to 100 cycles (5 hours)
Files changed:
- logger/decision_logger.go: Core matching and calculation logic
- api/server.go: API analysis window
- trader/auto_trader.go: AI decision analysis window
