追踪止损未在交易视图中触发（松树脚本）

Question

我是 pinescript 的新手，正在尝试编写代码，在 longcondtion（ema 交叉）之后进入，如果初始止损触发，策略退出 100% 数量。第一个目标的 50% 数量和剩余 50% 的数量应跟随超级趋势。当超级趋势改变方向时，它应该以剩余的 50% 退出，但即使超级趋势交叉，它也不会退出剩余的 50% 数量。短条件反之亦然

如果有人做过类似的代码，请建议我，提前谢谢。

if (longCond )
    strategy.entry("BUY",strategy.long)
    
if (shortCond )
    strategy.entry("SELL",strategy.short)


tar=input(defval=30.0,title="TARGET")

sl=input(defval=30.0,title="STOP LOSS")
tar:=tar/syminfo.mintick
sl:=sl/syminfo.mintick

 //adding stoploss and target option
strategy.exit("x1", from_entry="BUY", qty = 50, profit = tar,loss = sl)

strategy.exit("x1", from_entry="SELL",qty = 50, profit = tar,loss = sl)


if strategy.position_size>0 and abs(strategy.position_size)==50 and crossunder(close,atrStop)
    strategy.exit("x2", from_entry="BUY", qty_percent=100)
    

if strategy.position_size<0 and abs(strategy.position_size)==50 and crossover(close,atrStop)
    strategy.exit("x2", from_entry="SELL",qty_percent=100)

试试这个版本：

//@version=4
strategy("SLtrail", overlay = true,calc_on_every_tick=true,default_qty_value=100)

// === LOGIC ===

ratio = input(type=input.integer,defval=3,title="Multiplier (3x length, 4x length, etc)",options=[3,4,5,6,7,8,9,10])
longOnly = input(type=input.bool,defval=false,title="Long Only")
fast = ema(hl2,length)
slow = ema(hl2,length * ratio)
plot(fast,linewidth=2,color=color.orange,title="Fast")
plot(slow,linewidth=2,color=color.blue,title="Slow")

longCond = crossover(fast,slow)
shortCond = crossunder(fast,slow)

//length = input(10, "Length", minval = 2)
src = input(close, "Source")
factor = input(3, "Multiplier", minval = 0.25, step = 0.25)
st(src, atrlen, atrfactor) =>
    var max     = src

    [stop, uptrend]

    strategy.close("BUY", qty_percent=100)
