Isn't that a good answer enough? I mean if the missing data is made up or modeled differently each time new data is available, running a test over the same time period would obviously give you different results ...
Why do you believe this is not the reason for the problem?
Patrickwhat new quotes will come in to the history? new quotes will only be updating the most recent days. How will new quotes have any effect on old data?
If this is the answer then the question again is, "why doesn't it model the old data which isn't changing, why does it model that differently?"
Aragorn, I just read through this entire thread. First, gotta give you props for sticking with this. About a year ago, I spent every waking moment trying to come up with the holy grail of advisors. Fib levels, pivot points, stochastics, MA's, etc... Two lessons learned - a) the strategy tester is a complete waste of time. b) the demo account functions differently than a live account. I was able to come up with some code that traded with about 90% accuracy --- in the backtesting. On the demo account that dropped to 75% or so, and when I tried it live I was under 50% (which, with proper money management should still be usable). My point is, don't beat yourself up trying to optomize to the strategy tester, or demo account. It looks like you've got a good thing going. I'm going to take your advisor home, read through the code this weekend - and set it up on my live account trading .01 lots. That's the only way you will know if it works or not. Thanks for sharing your code!
