options question for tos users

  1. I have a question regarding spread hacker, say I input my parameters and I sort by probability of profit, what is that actually looking at to calculate prob of profit? Standard deviations? Also, can these be backtested? I'm just wondering how accurate these have been. I know it depends a lot on market activity, volatility, etc. but is it safe to say high probability of profit percentages are pretty accurate in the position finishing up that way. Do people take positions just using prob of profit and are successful with it?
