我想将长短策略转变为长策略

Question

我如何才能长期做这种策略，关闭多头头寸而不是做空呢？

非常感谢！

len        = input(21, minval=1)

mult       = input(3, minval=1)

//Line

atr        = wma(atr(1), len)

highestC   = highest(len)

lowestC    = lowest(len)

hiLimit    = highestC[1] - (atr[1] * mult)

loLimit    = lowestC[1] + (atr[1] * mult)

ret = 0.0

ret := close > hiLimit and close > loLimit ? hiLimit : close < loLimit and close < hiLimit ? loLimit : nz(ret[1])

plot(ret, color= blue , title = "Trend Trader")

//Trading

if low > ret and close < open

    strategy.entry("L", strategy.long)

if high < ret and close > open

    strategy.entry("S", strategy.short)

Answer 1

您的策略在满足条件（high < ret and close > open时执行空头头寸，并自动平仓多头头寸。

要长期关闭而不是短暂执行，请更改第39行：

strategy.entry("S", strategy.short)

到

strategy.close("L", when = high < ret and close > open)
