Variable Moving Average (VMA) by Chande?

[Antares66]

Hello , couldnīt find the original VMA indicator by Chande.
I know in NT8 there is a so called "VMA" indicator but which seems to be the VIDYA by Chande.
I donīt mean the ViDYA indicator which is often mistaken for the VMA.
Someone programmed the VMA for tradingview and Tos which isnīt original in their systems.
Is there a way to implement it here?


Thanks

Hello Antares66,

If you have the code or equation for what you want in another platform you can likely transition that over to NinjaScript. There is not a specific conversion process in that case however very often the different trading platforms have very similar code that can be used in similar ways.

The NT8 VMA can be duplicated so you could use that as a starting point if the equation you want is not far off from that. To make a duplicate you can open the original script in the NinjaScript editor and then Right click -> Save AS.



I look forward to being of further assistance.

Hi guys.

I do have it's code from another plataform, but I don't know how to use NinjaScript yet. In any case, that's the code and if someone manages to have it on NinjaScript, please, send it over.
