Pine-Script 中是否有可用的 FORCAST 函数？

Question

I am trying to convert an existing script into Pine-Script, and I am currently stuck in a function which is FORCAST, where I don't know what it is trying to do. Possible if I post the partial script here and if there is anyone that is able to interpret it?

Answer 1

if what you're looking for is indeed a linear regression like the Excel FORECAST function, please have a look on this example:

https://www.tradingview.com/pine-script-docs/en/v4/essential/Drawings.html#linear-regression

Normally such functions should have (at least) the following inputs:

1. known vector of X values (inputs)
2. known vector of Y values (outputs)
3. user X value for which the function will return a forecasted Y value

The example in the link will give you a fairly complete implementation of linear regression in Pine-script, but note it is meant to draw a line instead of making forecasts. You'll need to get some hands-on if you want to convert it into a function that returns you a certain Y value instead of the line.
