I am looking for a backtesting package that will for any single signal I give it show the average price after for a time. So not entry and exit. Just entry. Nice to haves: (1) standard deviation bars on this (2) it will store every such graph so that I can click through and look at each individual price action a little before and after and it is close to instant between the click and showing the graph (3) millisecond precision on backtest tick data (4) level 2 quote based backtesting
