This is Blau Tsi which originally uses a form of momentum in it's calculation, in this version it's using velocity instead, seems alright as far as smoothness and not to much lag. For the Tsi and it's signal moving averages there are the 37 options available and the velocity price has the 30+ price options.

ps) upon further testing some of the averages don't go well with this mod will eventually weed out all those that don't work and post an updated version.
