I modified the indi again by creating an "Open-Close" Adaptive ATR version (no gap)
Instead of using HIgh and Low in the calculation MathMax(o, c) and MathMin(o, c) are used
not sure if that's really useful, but more tuning variables the better i think
so here is v1.20
EDIT : sorry I posted in the wrong thread, it should've been in Volatility Indicator Thread (I put latest V1.30 there)
