使用 heikin ashi 的策略进入和退出，但它在 longcondition 中显示错误

Question

在长条件下显示错误。我也添加了错误

错误：

Add to Chart operation failed, reason: line 16: Syntax error at input 'openHA'

有什么办法可以纠正这个错误

我在下面添加了代码-

//@version=4 

strategy("Heikin Ashi Strategy on normal candles", shorttitle="HA Strategy", overlay=true)

openHA  = security(heikinashi(syminfo.tickerid), timeframe.period, open)
closeHA = security(heikinashi(syminfo.tickerid), timeframe.period, close)
highHA  = security(heikinashi(syminfo.tickerid), timeframe.period, high)
lowHA  = security(heikinashi(syminfo.tickerid), timeframe.period, low)

fromYear = year > 2019
toYear = year < 2021

longCondition = openHA = lowHA and closeHA[2] > openHA[2] 
if (longCondition and fromYear and toYear)
strategy.entry("Long 1", strategy.long)

closeCondition = closeHA = highHA
if (closeCondition)
strategy.close("Long 1")

plot(close)

Answer 1

这是因为你在语句中有两个=变量赋值。对于“等于”逻辑运算，您使用两个：openHa == lowHA。 closeCondition 行出现相同的错误，您需要在 if 语句中进行 indent/nest 操作。

if (longCondition and fromYear and toYear)
    strategy.entry("Long 1", strategy.long) // <-- this line one tab indented

使用 heikin ashi 的策略进入和退出，但它在 longcondition 中显示错误

strategy entry and exit using heikin ashi but it shows error in longcondition
