TradingView-当我做多时，我希望我的止损位于上一个柱的低点

Question

我在TradingView中有一个策略，该策略根据特定条件会持续很长时间。如果我对StopLoss和TakeProfit使用整数或百分比，则效果很好。

但是，我真的想将之前的柱线的止损设置为低。

执行Long时，我似乎无法保存变量。

Below不起作用，因为在每个蜡烛上都会更新low [1]：

inpTakeProfit   = input(2.0, title='Take Profit %', type=float)/100
takeProfitValue = strategy.position_avg_price * (1 + inpTakeProfit)
inpStopLoss     = low[1]
stopLossValue = inpStopLoss
entry = strategy.position_avg_price
useTakeProfit   = inpTakeProfit  > 0 ?  takeProfitValue : na
useStopLoss     = inpStopLoss    > 0 ?  stopLossValue   : na

如何保存变量并使它保持静态？

Answer 1

//Stop as last bars low and profit as percentage
entry = strategy.position_avg_price
inpTakeProfit   = input(2.0, title='Take Profit %', type=float)/100
takeProfitValue = strategy.position_avg_price * (1 + inpTakeProfit)
useTakeProfit   = inpTakeProfit  > 0 ?  takeProfitValue : na
**inpStopLoss     = valuewhen(allConditions, low, 0)**
stopLossValue = inpStopLoss
useStopLoss     = inpStopLoss    > 0 ?  stopLossValue   : na
