在松脚本中逐条满足某些条件

Question

如何检查每个柱是否满足某些条件？我想在每个柱完成时（逐个柱）检查慢速和快速 EMA 的交叉，直到交叉发生。我对此一无所知，很高兴告诉您如何操作？

Answer 1

您需要使用 if 运算符和 crossover 函数

//@version=4
study("My Script")

ema10 = ema(close, 10)
ema20 = ema(close, 20)
plot(ema10, color = color.red)
plot(ema20, color = color.green)

if crossover(ema10,ema20)
    label.new(bar_index, high, text = "Crossover ema10 over ema20")

在松脚本中逐条满足某些条件
