我如何调用请求。

我需要在Heikin Ashi Security中致电Ta.Sar，这给了我一个买入/出售信号以在Japatin中执行蜡烛价值。

//SAR security example (not working)
start = input(0.02)
increment = input(0.02)
maximum = input(0.2, "Max Value")
out = (request.security(ticker.heikinashi(syminfo.tickerid), timeframe.period, close) ta.sar(start, increment, maximum))
sarColor = out < low ? color.lime : color.red
plot(out, "ParabolicSAR", style=plot.style_cross, color=sarColor)

I need to call a ta.sar in heikin ashi security, that gives me a buy/sell signal to execute in japanise candles values.

//SAR security example (not working)
start = input(0.02)
increment = input(0.02)
maximum = input(0.2, "Max Value")
out = (request.security(ticker.heikinashi(syminfo.tickerid), timeframe.period, close) ta.sar(start, increment, maximum))
sarColor = out < low ? color.lime : color.red
plot(out, "ParabolicSAR", style=plot.style_cross, color=sarColor)

request.security（）函数3rd paramter是您希望返回的expression。在您的情况下，您需要关闭，而您要获得SAR。您还使用额外的括号，可以从代码中删除：

//@version=5
indicator(title="Money Flow Index", shorttitle="MFI", format=format.price, precision=2, timeframe="", timeframe_gaps=true)
start = input(0.02)
increment = input(0.02)
maximum = input(0.2, "Max Value")
out = request.security(ticker.heikinashi(syminfo.tickerid), timeframe.period, ta.sar(start, increment, maximum))
sarColor = out < low ? color.lime : color.red
plot(out, "ParabolicSAR", style=plot.style_cross, color=sarColor)

如果您希望在以后使用关闭的情况下，可以同时获得关闭和SAR：

//@version=5
indicator(title="Money Flow Index", shorttitle="MFI", format=format.price, precision=2, timeframe="", timeframe_gaps=true)
start = input(0.02)
increment = input(0.02)
maximum = input(0.2, "Max Value")
[_close, out] = request.security(ticker.heikinashi(syminfo.tickerid), timeframe.period, [close, ta.sar(start, increment, maximum)])
sarColor = out < low ? color.lime : color.red
plot(out, "ParabolicSAR", style=plot.style_cross, color=sarColor)
plot(_close)

The request.security() function 3rd paramter is the expression you wish to return. In you case, you're requesting Close, while you want to get sar. You also use an extra parenthesis you can delete from your code:

//@version=5
indicator(title="Money Flow Index", shorttitle="MFI", format=format.price, precision=2, timeframe="", timeframe_gaps=true)
start = input(0.02)
increment = input(0.02)
maximum = input(0.2, "Max Value")
out = request.security(ticker.heikinashi(syminfo.tickerid), timeframe.period, ta.sar(start, increment, maximum))
sarColor = out < low ? color.lime : color.red
plot(out, "ParabolicSAR", style=plot.style_cross, color=sarColor)

You can get both Close and sar if you wish using Close at a later time:

//@version=5
indicator(title="Money Flow Index", shorttitle="MFI", format=format.price, precision=2, timeframe="", timeframe_gaps=true)
start = input(0.02)
increment = input(0.02)
maximum = input(0.2, "Max Value")
[_close, out] = request.security(ticker.heikinashi(syminfo.tickerid), timeframe.period, [close, ta.sar(start, increment, maximum)])
sarColor = out < low ? color.lime : color.red
plot(out, "ParabolicSAR", style=plot.style_cross, color=sarColor)
plot(_close)
