I'm sorry. But, I do not understand what you are trying to say.
You have described a system that took trades, got stopped out on some subset, then took additional trades. If backtesting for the same time period over which that system was run, then the backtester should show the same results as what would have taken place when live trading the system.
I still don't understand what you mean by applying the stop after the backtest has completed. What are you referring to as a "backtest"? Are we talking about the same thing? I'm referring to clicking on the Backtest button from the AA window. Are you perhaps referring to calling the Equity() function from within code before an ApplyStop() function call?
Running a backtest is for a pre-determined period; start to finish. If you want the backtest to reflect some additional actions taken beyond the original finish date, then extend the finish date. Trying to compare trading results for one (longer) period to the backtest results of a second (shorter) period is comparing apples to oranges.
I fail to see why you would ever need to export trades and manually alter them.
If it's not imporant to you, feel free to let the thread die. Otherwise, it might help if you provided a detailed scenario that captures exactly what you're trying to express.

But if you performed a backtest, and then applied stops after the fact, you would have the same number of trades but then have the stops - the performance could be quite different, and the number of trades will logically go up when you're using stops in AB. Now one way around this is to export the trades to, say, Excel and then manually apply the stops, but I'm wondering if there is anything in AB to deal with this issue.
