仅绘制交易视图历史数据

Question

我最大的问题是我只想要指标上的历史数据，因为实时变化太大，会打印出一堆我不想要的买入/卖出信号。以下是我到目前为止的代码。

基本上，我想要历史警报，并且我只想在加载电视时显示历史数据。

免责声明：我使用了 Mehdi 的这个开源代码，并且一直在对其进行编辑以修复它/从中获取我需要的东西。

感谢您抽出宝贵时间提供帮助。

plot(dn1, "Lower Band", color = #3286c3, linewidth = 2) // Lower Band
plot(mid1, "Middle of Bands", color = yellow, linewidth = 2) // Middle of Bands
plot(slowMA1, "Slow MA", color=green, linewidth=2) // Plot Slow MA
plot(fastMA1, "Fast MA", color=red, linewidth=1) // Plot Fast MA

if (crossover(fastMA1, slowMA1)) strategy.entry("sell", strategy.long, comment="Buy")

if (crossunder(fastMA1, slowMA1)) strategy.entry("Sell", strategy.short, comment="Sell")

Answer 1

您可以使用History reference operator 访问历史数据。

例如，你可以这样做

crossover(fastMA1[1], slowMA1[1]) 看看交叉是否发生在一个小节之前。
