Thanks for the prompt reply, I have already seen this very comprehensive moving average indicator.
I wanted to use the SMMA and I believe that the average indicator 9.4 and earlier with longer averages of the type 200 or 400 tends to twist on the price and then start, also in this case with not very long histories it tends not to give optimal values, in practice, the average starts from the candle, while the indicator I posted is like the standard moving average smoothed of MT, if possible I wanted to try to fix and maybe improve mine.

I hope there is more help

I also insert the vidya because it can be useful for someone
