I dont think it exists, I couldnt find it any way I searched, maybe it is part of a bigger indicator. This is a really basic code, all it does, it shows the tick/pip size of the candles forming. You can adjust on how many candles should it show. Also because the code counts the point size of the candles from high to low, you can adjust that how many ticks are in one point, like for ES and NQ 4 ticks to a point, which is the basic setting. It helps me with entrys when I calculate the contract size so my risk/reward stays pretty much the same depending on the candle size for my entrys.
