[RESEARCH] Rate of Change

22 พ.ย. 2018

Hello traders and developers!

I was wondering how built-in "roc" function in Pine is defined and calculated so I made a little research.

I examined 4 samples:
1) "roc" function itself
2) "roc" according to its description
3) price change ratio
4) price percent change ratio

The results of the first and fourth samples are identical.

So, TV built-in roc(source, length) = 100 * change(source, length) / source[length].
And it's description is incorrect.

If you didnt know it - now you know it.

Good luck!
