Pine script TradingView PinScript值当不使用for迭代器变量（i）时
我想用valuewhen获得最新的五个curPosition。但它不起作用。 我认为用for I迭代器调用valuewhencurPosition>0，curPosition，I是个问题。你能帮我吗Pine script TradingView PinScript值当不使用for迭代器变量（i）时,pine-script,Pine Script,我想用valuewhen获得最新的五个curPosition。但它不起作用。 我认为用for I迭代器调用valuewhencurPosition>0，curPosition，I是个问题。你能帮我吗 //@version=4 strategy(title="Test", shorttitle="Test", overlay=true) // curPosition // 0 == "-" // 1 == "LONG" // 2 == "SHORT" curPosition = 0 longC

plotchar(longCnt, "LONG CNT", "", location=location.top)

plotchar(noneCnt , "NONE CNT", "", location=location.top)
我找到了根本原因。别针脚本引擎工作异常 请参阅pine脚本文档，参见下面的说明
//@version=4
study("SMA in for loop")
sum = 0
for i = 1 to 2
sum := sum + sma(close, i)
plot(sum)
