Hello, I was wondering if anyone could point me in the direction of an indicator, for any platform, MT4, thinkorswim, ninjatrader, etc, that can calculate the implied volatility for a given time period (i.e. week, day, hour, 15 minutes, etc) and then provide standard deviation levels for that time period. I.e. it calculates the last 4 hours implied volatility and gives me standard deviation deviation levels for the next 4 hours time period. Any help would be appreciated.
