Pine Script背离策略入场延迟问题排查求助

我开发了一款基于背离（Divergence）的TradingView交易策略，能在指标图表上及时识别并标记背离信号，但实际入场操作会延迟若干K线。策略核心是捕捉价格与指标反向运行的背离形态，包括常规多空背离、隐藏多空背离，信号出现后会在图表上高亮显示，但交易不会立即执行，存在明显的延迟等待期。调整回溯范围参数后问题仍未解决，求入场延迟的原因及优化方案。

• 入场信号的双重滞后：代码中入场信号判断使用了bull = bullCond[lbR] or hiddenBullCond[lbR]，这里的[lbR]会让信号滞后lbR根K线（默认5根）。而图表标记用offset=-lbR把信号回溯显示到实际触发的K线，导致视觉上信号即时显示，但入场逻辑却额外延迟了lbR根K线。
• 枢轴点确认的叠加延迟：ta.pivotlow()/ta.pivothigh()本身需要等待lbR根K线走完才能确认当前K线是枢轴点，这是合理的延迟，但入场逻辑额外叠加的[lbR]引用，让延迟翻倍。

1. 移除入场信号的滞后引用：将bull = bullCond[lbR] or hiddenBullCond[lbR]修改为bull = bullCond or hiddenBullCond，同理修改bear的定义，让入场信号在背离条件满足的同一根K线触发。
2. 保留图表标记的回溯显示：继续使用offset=-lbR让标记显示在实际枢轴点K线上，保持视觉上的信号及时性，同时让入场逻辑与条件判断同步。
3. 平衡延迟与信号准确性：若想进一步降低延迟，可减小lbR（Pivot Lookback Right）参数，但这会增加假信号概率，需根据品种特性调整。
