我的策略难以解决，但无法在pine编辑器中出售

Question

我正在使用pine编辑器制定策略，即当绿色的D线跌破17.5时买入，然后在D线超过78时卖出。从图表中可以看出，我应该买入卖了几次，但只买了一次，什么也没做。我似乎无法弄清楚我所缺少的。代码的底部是我告诉该策略并在该策略中出售的位置。谢谢

strategy("stochastic")
length = input(21, minval=1, title="length")  
rsilength = input(21, minval=1, title="rsi length")  
smoothk = input(4, minval=1, title="smoothk")
smoothd = input(10, minval=1, title="smoothd")
rsi = rsi(close, rsilength)

sto = stoch(close,highest(length),lowest(length), length)
K = sma(sto,smoothk)
D = sma(K,smoothd)

//plot(rsi, title="rsi", color=color.black)
plot(D, title="%D",color=color.green)
plot(K, title="%K",color=color.red)

hline(78,title="upper limit", color=color.red)
hline(17, title="lower limit",color=color.blue)
//plot(sto, title = "sto",color=color.black)


// === INPUT BACKTEST RANGE ===
FromMonth = input(defval = 8, title = "From Month", minval = 1, maxval = 12)
FromDay   = input(defval = 5, title = "From Day", minval = 1, maxval = 31)
FromYear  = input(defval = 2019, title = "From Year", minval = 2017)
ToMonth   = input(defval = 9, title = "To Month", minval = 1, maxval = 12)
ToDay     = input(defval = 1, title = "To Day", minval = 1, maxval = 31)
ToYear    = input(defval = 9999, title = "To Year", minval = 2017)

// === FUNCTION EXAMPLE ===
start     = timestamp(FromYear, FromMonth, FromDay, 00, 00)  // backtest start window
finish    = timestamp(ToYear, ToMonth, ToDay, 23, 59)        // backtest finish window
window()  => time >= start and time <= finish ? true : false // create function "within window of time"

// === EXECUTION ===
shares = 10000/close
buy = crossunder(D,17.5)
sell = crossover(D,78)

strategy.entry("buy", shares, when = window() and buy)  // buy long when "within window of time" AND crossover
strategy.close("sell", when = window() and sell)                // sell long when "within window of time" AND crossunder         

这应该买卖两次，如图中突出显示。 https://ibb.co/37L0wSK这是链接，很抱歉，我没有足够的代表来发布图像。

您的strategy.close()呼叫与strategy.entry()呼叫使用的订单ID不同。我在最后3行中添加了标记（您可以通过输入将其关闭）以显示满足条件的位置。

  

注意：请确保您在脚本中包含第一行   传输Pine脚本。这是指定的编译器指令   代码使用的是哪个版本的Pine，因此很重要。

rsi = rsi(close, rsilength)

sto = stoch(close,highest(length),lowest(length), length)
