Soul I know it is possible and I even have one, i will post it when I find it, but it will work only on real time data, it doesnt look on historical data... on the other side I believe it calculates on up/dn ticks and not real bid ask volume on TS... Linnsoft its about the only soft that has reliable performance on this type of data until now... and has the abilty to recalculate historical data and plot it... maybe the most near competitor its topgunsoftware thought their aproach is quite diferent... cheers Walter.
