在 Pine 中：如果价格达到低于入场价的 X 个刻度，如何完全关闭这个多头订单

Question

到目前为止我正在使用这段代码：

strategy.entry("My Long Entry ", strategy.long)
strategy.exit("My Exit 1", from_entry = "My Long Entry ", profit=15000, qty_percent = 50)
strategy.exit("My Exit 2", from_entry = "My Long Entry ", qty_percent = 50, trail_offset=10000, trail_points=15000)

但我想避免这种回撤：

那么，当价格达到刚好低于入场价的水平（我想用刻度指定）时，我怎样才能关闭整个交易（请注意，我在两个退出中都使用了 qty_percent）？

谢谢

Answer 1

您可以使用：

var Limit_Below_Entry_Price = 0.0
Limit_Value = 100 // Here you choose how many $$$ below your entry price trigger the close_all()

if (your logic to decide to long)
    strategy.entry("My Long Entry ", strategy.long)
    Limit_Below_Entry_Price := close - Limit_Value
    
    strategy.exit("My Exit 1", from_entry = "My Long Entry ", profit=15000, qty_percent = 50)
    strategy.exit("My Exit 2", from_entry = "My Long Entry ", qty_percent = 50, trail_offset=10000, trail_points=15000)

if close < Limit_Below_Entry_Price
        strategy.close_all()
