当执行另一个条件时，如何仅首次越过

发布于 2025-02-12 03:30:23 字数 501 浏览 0 评论 0原文

我需要编写此指标： MFI不到20岁，然后越过20个（这是主要条件）当RSI与RSIMA首次交叉时，出现了买信号，

我编写了此代码：

    var sessionStart = false
if ta.crossover(mf,20)
    sessionStart := true
var rsicross = false
if rsi < rsiMA or rsi > rsiMA or ta.crossunder(rsi,rsiMA) 
    rsicross := false
if ta.crossover(rsi,rsiMA)
    rsicross := true
//====
buyCondition = sessionStart and rsicross

问题是：所有RSI RSIMA十字架都会给出购买信号，因为MFI MFI以前越过20个。我需要在MFI交叉20之后，首先是RSI，RSIMA Crossing提供购买信号。有人可以帮我吗，

谢谢

原文

I need to write this indicator :
MFI be under 20 and then cross over 20 ( it is main condition)
the buy signals appears when first cross up of RSI to rsiMA

I write this code :

    var sessionStart = false
if ta.crossover(mf,20)
    sessionStart := true
var rsicross = false
if rsi < rsiMA or rsi > rsiMA or ta.crossunder(rsi,rsiMA) 
    rsicross := false
if ta.crossover(rsi,rsiMA)
    rsicross := true
//====
buyCondition = sessionStart and rsicross

the problem that : all the rsi rsiMA crosses give buy signals because the main condition MFI crossed 20 before.
I need after MFI cross up 20 , just first rsi , rsiMA crossing give buy signals.
can someone help me please

thank you

在购买条件发生时，您将不得不将买入条件重置为false。因此，在MF交叉发生之前，它不会再次提供购买条件。

if buyCondition 
    sessionStart:false

You will have to reset the buyCondition back to false when buy condition has occured. So that it will not give buy condition again until mf crossover occurs.
