Question

的ATR TP / SL编码问题

我需要使用过去的平均真实范围来编码止盈和止损。我有一个问题，我的代码正在计算最新的ATR，但我找不到从条目中锁定ATR号码的方法。蜡烛关闭后，ATR正在计算，这意味着蜡烛处于活动状态时不存在。将图片添加到我已标记了我要寻找的内容以及松木正在计算的位置。

strategy.exit("TP3", "Long", qty_percent = 20, limit=atrPlus3)
strategy.exit("SL", "Long", stop = atrStop)
strategy.close ( "Long", when = exitCondition)

Answer 1

我只是保留入口处的atr值，就像这样：

entryAtr = entryAtr[1]

if (longCondition)
    strategy.entry("Long", strategy.long)
    entryAtr := atrBand // save the value to use it for exit
