fix(trader): add backend safety checks for partial_close (#713)

* fix(trader): add backend safety checks for partial_close After PR #415 added partial_close functionality, production users reported two critical issues: 1. **Exchange minimum value error**: "Order must have minimum value of $10" when remaining position value falls below exchange threshold 2. **Unprotected positions after partial close**: Exchanges auto-cancel TP/SL orders when position size changes, leaving remaining position exposed to liquidation risk This PR adds **backend safety checks** as a safety net layer that complements the prompt-based rules from PR #712. **Protection**: Before executing partial_close, verify remaining position value > $10 ```go const MIN_POSITION_VALUE = 10.0 // Exchange底线 remainingValue := remainingQuantity * markPrice if remainingValue > 0 && remainingValue <= MIN_POSITION_VALUE { // 🔄 Auto-correct to full close decision.Action = "close_long" // or "close_short" return at.executeCloseLongWithRecord(decision, actionRecord) } ``` **Behavior**: - Position $20 → partial_close 50% → remaining $10 ≤ $10 → Auto full close ✅ - Position $30 → partial_close 50% → remaining $15 > $10 → Allow partial close ✅ **Protection**: Restore TP/SL orders for remaining position if AI provides new_stop_loss/new_take_profit ```go // Exchanges auto-cancel TP/SL when position size changes if decision.NewStopLoss > 0 { at.trader.SetStopLoss(symbol, side, remainingQuantity, decision.NewStopLoss) } if decision.NewTakeProfit > 0 { at.trader.SetTakeProfit(symbol, side, remainingQuantity, decision.NewTakeProfit) } // Warning if AI didn't provide new TP/SL if decision.NewStopLoss <= 0 && decision.NewTakeProfit <= 0 { log.Printf("⚠️⚠️⚠️ Warning: Remaining position has NO TP/SL protection") } ``` **Improvement**: Show position quantity and value to help AI make better decisions ``` Before: | 入场价100.00 当前价105.00 | 盈亏+5.00% | ... After: | 入场价100.00 当前价105.00 | 数量0.5000 | 仓位价值52.50 USDT | 盈亏+5.00% | ... ``` **Benefits**: - AI can now calculate: remaining_value = current_value × (1 - close_percentage/100) - AI can proactively avoid decisions that would violate $10 threshold - Added MIN_POSITION_VALUE check before execution - Auto-correct to full close if remaining value ≤ $10 - Restore TP/SL for remaining position - Warning logs when AI doesn't provide new TP/SL - Import "math" package - Calculate and display position value - Add quantity and position value to prompt - Complements PR #712 (Prompt v6.0.0 safety rules) - Addresses #301 (Backend layer) - Based on PR #415 (Core functionality) | Layer | Location | Purpose | |-------|----------|---------| | **Layer 1: AI Prompt** | PR #712 | Prevent bad decisions before they happen | | **Layer 2: Backend** | This PR | Auto-correct and safety net | **Together they provide**: - ✅ AI makes better decisions (sees position value, knows rules) - ✅ Backend catches edge cases (auto-corrects violations) - ✅ User-friendly warnings (explains what happened) - [x] Compiles successfully (`go build ./...`) - [x] MIN_POSITION_VALUE logic correct - [x] TP/SL restoration logic correct - [x] Position value display format validated - [x] Auto-correction flow tested This PR can be merged **independently** of PR #712, or together. Suggested merge order: 1. PR #712 (Prompt v6.0.0) - AI layer improvements 2. This PR (Backend safety) - Safety net layer Or merge together for complete two-layer protection. --- 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: tinkle-community <tinklefund@gmail.com> * fix: add error handling for markPrice type assertion - Check type assertion success before using markPrice - Return error if markPrice is invalid or <= 0 - Addresses code review feedback from @xqliu in PR #713 * test(trader): add comprehensive unit tests for partial_close safety checks - Test minimum position value check (< 10 USDT triggers full close) - Test boundary condition (exactly 10 USDT also triggers full close) - Test stop-loss/take-profit recovery after partial close - Test edge cases (invalid close percentages) - Test integration scenarios with mock trader All 14 test cases passed, covering: 1.
