风险管理:如果已经做多,则不要下新订单 [英] Risk Management: If already long then do not place new order
问题描述
如果标志已经指示 long,则不应有新标志指示 long.如果标志不表示长计算表达式
If the flag is already indicating long, there should not be a new flag indicating long. If flag does not indicate long evaluate the expression
longCondition = if (strategy.long) ? false: (rsi<30) and (close>moving_avg)
shortCondition = if (strategy.short) ? false: (rsi>70) and (close<moving_avg)
处理脚本...
第 30 行:不匹配的输入shortCondition"期待行尾"没有续行'
line 30: mismatched input 'shortCondition' expecting 'end of line without line continuation'
推荐答案
我认为这是一个指标而不是策略.因为您可以使用 pyramiding
参数在策略中配置要在同一方向上拥有多少条目.默认为 0,所以如果这是一个策略并且您没有更改金字塔参数,那应该没有问题.
I assume this is an indicator and not a strategy. Because you can configure how many entries you want to have in the same direction in a strategy with the pyramiding
parameter. Default is 0, so if this is a strategy and you haven't changed the pyramiding parameter, it shouldn't be a problem.
对于指标,您可以使用这样的变量:
For indicators, you can use a variable like this:
//@version=4
study("My Script", overlay=true)
var isLong = false
var isShort = false
rsi = rsi(close, 14)
moving_avg = ema(close, 9)
buySignal = not isLong and (rsi<50) and (close>moving_avg) // Buy only if we are not already long
sellSignal = not isShort and (rsi>50) and (close<moving_avg) // Sell only if we are not already short
if buySignal
isLong := true
isShort := false
if sellSignal
isLong := false
isShort := true
plotshape(series=buySignal, title="BUY", text="BUY", style=shape.triangleup, location=location.belowbar, color=color.green, size=size.small)
plotshape(series=sellSignal, title="SELL", text="SELL", style=shape.triangledown, location=location.abovebar, color=color.red, size=size.small)
