v2 to v4, heikin ashi ema

Question

我正在尝试将此 v2 脚本转换为 v4，以便添加更多内容，但我似乎无法像 v2 脚本那样复制移动的 heikin ashi 行。我做的一切都是一样的，所以我不确定问题是什么。

我尝试更改班次并查看了参考，但我无法弄清楚我做错了什么。请帮忙

v2 代码：

//@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")
res1 = input(title="Heikin Ashi EMA Time Frame", type=resolution, defval="45")
mhshift = input(0,title="Heikin Ashi EMA Time Frame Shift")
fama = input(1,"Heikin Ashi EMA Period")
test = input(0,"Heikin Ashi EMA Shift")
sloma = input(40,"Slow EMA Period")
slomas = input(0,"Slow EMA Shift")
macdf = input(false,title="With MACD filter")
res2 = input(title="MACD Time Frame", type=resolution, 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, res, 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,res2,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,linewidth=2,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)

v4 代码：

// © zainali282000

//@version=4
strategy("HAF1v4", overlay=true, initial_capital=100,currency=currency.USD, default_qty_type = strategy.percent_of_equity, default_qty_value = 25, commission_type = strategy.commission.percent, commission_value = 0.04, margin_long = 4, margin_short = 4)

//Get Heikin Ashi Data
res = input(title="Heikin Ashi Candle Time Frame", type=input.resolution, defval="")
hshift = input(2,title="Heikin Ashi Candle Time Frame Shift")
res1 = input(title="Heikin Ashi EMA Time Frame", type=input.resolution, defval="45")
mhshift = input(0,title="Heikin Ashi EMA Time Frame Shift")
fama = input(1,"Heikin Ashi EMA Period")
test = input(0,"Heikin Ashi EMA Shift")
sloma = input(40,"Slow EMA Period")
slomas = input(0,"Slow EMA Shift")
macdf = input(false,title="With MACD filter")
res2 = input(title="MACD Time Frame", type=input.resolution, defval="15")
macds = input(0,title="MACD Shift")

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

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

//strategy
golong =  crossover(fma,sma)
goshort =   crossunder(fma,sma)

strategy.entry("Buy",strategy.long,when = golong)
strategy.entry("Sell",strategy.short,when = goshort)

Answer 1

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