charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #818 ## 问题 传递给 AI 决策的持仓盈亏百分比只计算价格变动,未考虑杠杆倍数。 例如:10倍杠杆,价格上涨1%,AI看到的是1%而非实际的10%收益率。 ## 改动 1. 修复 buildTradingContext 中的盈亏百分比计算 - 从基于价格变动改为基于保证金计算 - 收益率 = 未实现盈亏 / 保证金 × 100% 2. 抽取公共函数 calculatePnLPercentage - 消除 buildTradingContext 和 GetPositions 的重复代码 - 确保两处使用相同的计算逻辑 3. 新增单元测试 (trader/auto_trader_test.go) - 9个基础测试用例(正常、边界、异常) - 3个真实场景测试(BTC/ETH/SOL不同杠杆) - 测试覆盖率:100% 4. 更新 .gitignore - 添加 SQLite WAL 相关文件 (config.db-shm, config.db-wal, nofx.db) ## 测试结果 ✅ 所有 12 个单元测试通过 ✅ 代码编译通过 ✅ 与 GetPositions 函数保持一致 ## 影响 - AI 现在能够准确评估持仓真实收益率 - 避免因错误数据导致的过早止盈或延迟止损 --- trader/auto_trader.go | 26 ++++---- trader/auto_trader_test.go | 118 +++++++++++++++++++++++++++++++++++++ 2 files changed, 131 insertions(+), 13 deletions(-) create mode 100644 trader/auto_trader_test.go diff --git a/trader/auto_trader.go b/trader/auto_trader.go index 8eec4a42..0df685b1 100644 --- a/trader/auto_trader.go +++ b/trader/auto_trader.go @@ -622,14 +622,6 @@ func (at *AutoTrader) buildTradingContext() (*decision.Context, error) { unrealizedPnl := pos["unRealizedProfit"].(float64) liquidationPrice := pos["liquidationPrice"].(float64) - // 计算盈亏百分比 - pnlPct := 0.0 - if side == "long" { - pnlPct = ((markPrice - entryPrice) / entryPrice) * 100 - } else { - pnlPct = ((entryPrice - markPrice) / entryPrice) * 100 - } - // 计算占用保证金(估算) leverage := 10 // 默认值,实际应该从持仓信息获取 if lev, ok := pos["leverage"].(float64);
