Pine Script Multi Time Frame - 我的策略是重绘，我不知道为什么

如何解决Pine Script Multi Time Frame - 我的策略是重绘，我不知道为什么

我以为我了解如何避免重新绘制，但我仍然看到图表上的交易没有与警报对齐，反之亦然。

我的脚本从 60m 图表中获取数据以在 15m 图表上进行交易。我正在访问 60m（至少 4 个柱线）的历史数据，如果 barstate.isconfirmed，我只输入 15m 的交易。我看到交易触发警报然后消失，或者从未触发警报的交易回溯性显示。

据我所知，我编写了我的脚本，因此未来的数据不应影响历史决策，但显然有些事情正在发生。我不知所措
