松树脚本多时间框架-我的策略是重新绘制，我不知道为什么

Question

我以为我知道如何避免重新绘制，但我仍然看到我的图表上的交易没有排队提醒，反之亦然。

我的脚本从60m图中获取数据，在15m图上进行交易。我正在访问6000万美元的历史数据(至少有4条)，而且我只在1500万美元的barstate.isconfirmed上进行交易。我看到交易触发警报，然后消失，或者从未触发警报的交易可以追溯性地出现。

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，但显然正在发生一些事情。我不知所措

i_stopPercent   = input(group="Trade Settings", title="Stop Percent", type=input.float, defval=0.05, maxval=1.0, minval=0.001)  // how much (percentage) can price fall before exiting the trade

// declare order variables

var stop        = 0.0   // the price that will trigger as stop loss
var entryPrice  = 0.0   // the price when the trade was entered

// build stochastic
sto = stoch(close, high, low, i_length)
K   = sma(sto, i_k)
D   = sma(K, i_d)

// get stochastic trend
stoch_upTrend = D > D[1]

// get stochastic trend for 60 minute
stoch_60         = security(syminfo.tickerid, "60", D)
stoch_60_upTrend = (stoch_60[4] >= stoch_60[8])

// entry
if (D < i_buyThreshold) and stoch_upTrend and stoch_60_upTrend and barstate.isconfirmed and strategy.position_size == 0
    recentHigh := close
    entryPrice := close
    stop       := (close * (1-i_stopPercent)) 
    strategy.entry(id="60-15-Long", long=strategy.long, comment='buy')

// update recent high, trailing stop

    recentHigh := close

我现在意识到这已经很老了，但我认为问题是(D < i_buyThreshold)可以重新绘制，而stoch_upTrend =D> D1也可以重新绘制。您可以尝试添加if barstate.isconfirmed作为父作用域，然后添加下面的其他if语句。

但是，如果这不起作用，则需要将D< i_buyThreshold)更改为D1 < i_buyThreshold)，并将stoch_upTrend =D> D1更改为stoch_upTrend = D1 > D2。这样，您就可以回顾以前的条形图，以检查是否满足了条件，并且这个栏已经关闭了。由于您正在查看的酒吧已经关闭，它不会改变。这要么是真的，要么不是真的。因此，您也不需要将barstate.isconfirmed作为if语句的一部分。
