Pine 脚本用于多个时间范围内的一些 EMA

Question

我正在尝试构建一个脚本，该脚本多次显示相同的 EMA 长度但在不同的时间范围内运行。我无法弄清楚时间表部分。无论我做什么，它都只能让我将所有 ema 调整为 1 个时间范围，我真的希望在许多不同的时间线上拥有相同的 ema。

例如，我想让 AAPL 在 1 分钟图表上显示 6 个不同的 20 个 EMA，但每个 6 个 EMA 都在不同的时间范围内。即1分钟、10分钟、60分钟、240分钟等。

Answer 1

使用secutiry()函数。

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

plot(ema(close, 10))
plot( security("AAPL", "1", ema(close,10)))

其他时间段依此类推。

Answer 2

需要在每个时间段的安全调用上下文中调用 ema() 函数

ema20_1 = security("AAPL", 1, ema(close, 20))
ema20_5 = security("AAPL", 5, ema(close, 20))
ema20_10 = security("AAPL", 10, ema(close,20))

plot(ema20_1)
plot(ema20_5)
plot(ema20_10)

此外，在这种情况下，图表的时间范围必须为 1 分钟（或更短），以便安全调用参考的时间范围不会低于图表的时间范围。
