在strategy.exit之后等待

Question

在策略停止(退出)后，我想在进入新交易之前等待。

我试着使用but，但是我找不到一个满足最后一个退出的条件。

我希望在退出发生后等待4个小时才能进入一个新的交易。

//@version=3
strategy("ABC", shorttitle="ABC", initial_capital=1000, commission_type = strategy.commission.percent, commission_value = 0.075, overlay = true, linktoseries = true)
nominal = 1000/close
SL = 0.0
SLold = nz(SL[1])
SL :=  max(max(max(strategy.position_avg_price,ohlc4)-atr(10)*3, strategy.position_avg_price * 0.96), SLold)
buy = cci(close,40)<50
testPeriodStart = timestamp(2018,2,1,0,0)
if time >= testPeriodStart 
    strategy.entry("Long", strategy.long, nominal, when = buy)
    strategy.exit("Exit", "Long", stop = SL)
plot(SL, color = #006400)

Answer 1

尝尝这个。

//@version=3
strategy("ABC", shorttitle="ABC", initial_capital=1000, commission_type = strategy.commission.percent, commission_value = 0.075, overlay = true, linktoseries = true)
nominal = 1000/close

// create a variable with time of exit
timeExit = 0.0
timeExit := nz(timeExit[1])

msToHours(timeMs) =>
    timeMs / 1000 / 60 / 60

isMoreThan4H() =>
    msToHours(time - timeExit) >= 4

// detect the exit
if strategy.position_size < strategy.position_size[1]
    timeExit := time

SL = 0.0
SLold = nz(SL[1])
SL :=  max(max(max(strategy.position_avg_price,ohlc4)-atr(10)*3, strategy.position_avg_price * 0.96), SLold)
buy = cci(close,40)<50
testPeriodStart = timestamp(2018,2,1,0,0)
if time >= testPeriodStart 
    strategy.entry("Long", strategy.long, nominal, when = buy and isMoreThan4H())   // Here added a check that is more than 4h since last exit
    strategy.exit("Exit", "Long", stop = SL)


plot(SL, color = #006400)
