如何在 hline 上方或下方的随机交叉上设置多头条件

Question

我是 pinescript 的新手，我很难为随机交叉编写条件

• 进入80以上交叉点的空头头寸
• 输入交叉点低于 20 的多头头寸

longCondition = crossover(sma(stoch(close, high, low, 13)), sma(15, 5) iff(close <=20))

*短句Condotion的副词

Answer 1

此代码示例将带您上路。

//@version=4
study("SO", overlay=true, scale=scale.left)

var loLevel = input(20, "Level Low",            minval=0, maxval=100)
var hiLevel = input(80, "Level High",           minval=0, maxval=100)
var stLen   = input(13, "Stochastic Length",    minval=1)

st      = stoch(close, high, low, 13)
hiCross = crossover(st, hiLevel)
loCross = crossunder(st, loLevel)

shortCondition  = hiCross
longCondition   = loCross

hline(loLevel)
hline(hiLevel)

plot(st)

bgcolor(hiCross ? color.red   : na, 80)
bgcolor(loCross ? color.green : na, 80)
