Fix critical balance validation and add comprehensive trading features
- Fixed CoinGecko API rate limiting with fallback SOL price (68.11) - Corrected internal API calls to use proper Docker container ports - Fixed balance validation to prevent trades exceeding wallet funds - Blocked 0.5 SOL trades with only 0.073 SOL available (~2.24) - Added persistent storage for positions, trades, and pending orders - Implemented limit order system with auto-fill monitoring - Created pending orders panel and management API - Added trades history tracking and display panel - Enhanced position tracking with P&L calculations - Added wallet balance validation API endpoint - Positions stored in data/positions.json - Trade history stored in data/trades.json - Pending orders with auto-fill logic - Real-time balance validation before trades - All trades now validate against actual wallet balance - Insufficient balance trades are properly blocked - Added comprehensive error handling and logging - Fixed Docker networking for internal API calls - SPOT and leveraged trading modes - Limit orders with price monitoring - Stop loss and take profit support - DEX integration with Jupiter - Real-time position updates and P&L tracking Tested and verified all balance validation works correctly
