v2 到 v4，heikin ashi ema

如何解决v2 到 v4，heikin ashi ema

我正在尝试将此 v2 脚本转换为 v4，以便我可以添加更多内容，但我似乎无法像 v2 脚本那样复制移动的 heikin ashi 行。我做的一切都一样，所以我不确定问题是什么。

我尝试更改班次并查看参考资料，但我无法弄清楚我做错了什么。请帮忙

//@version=2
//Heikin Ashi F1

strategy("Heikin Ashi F1",shorttitle="HAS F1",overlay=true,default_qty_value=50,initial_capital=100,currency=currency.USD)
res = input(title="Heikin Ashi Candle Time Frame",type=resolution,defval="5")
hshift = input(2,title="Heikin Ashi Candle Time Frame Shift")

mhshift = input(0,title="Heikin Ashi EMA Time Frame Shift")

macdf = input(false,title="With MACD filter")
res2 = input(title="MACD Time Frame",defval="15")
macds = input(0,title="MACD Shift")




//Heikin Ashi Open/Close Price
ha_t = heikinashi(tickerid)
ha_open = security(ha_t,res,open[hshift])
ha_close = security(ha_t,close[hshift])
mha_close = security(ha_t,res1,close[mhshift])

//macd
[macdLine,signalLine,histLine] = macd(close,12,26,9)
macdl = security(ha_t,res2,macdLine[macds])
macdsl= security(ha_t,signalLine[macds])

//Moving Average
//THE PROBLEM IS FMA
fma = ema(mha_close[test],fama)
sma = ema(ha_close[slomas],sloma)
plot(fma,title="MA",color=lime,linewidth=2,style=line)
plot(sma,title="SMA",color=red,style=line)



//Strategy
Golong =  crossover(fma,sma) and (macdl > macdsl or macdf == false )
goshort =   crossunder(fma,sma) and (macdl < macdsl or macdf == false )

strategy.entry("Buy",strategy.long,when = Golong)
strategy.entry("Sell",strategy.short,when = goshort)
// strategy.exit("ExitLong","Buy",limit = close+atr)
// strategy.exit("ExitShort","Sell",limit = close - at)

解决方法

security 调用中的问题。对于 v2 security(ha_t,res,open[hshift])，v4 的等效项是 security(ha_t,open[hshift],lookahead=barmerge.lookahead_on)
