Good for you Julian. Keep learning. Stay dedicated. Ignore the negative comments/ Ultimately you have to test your ATS on live data with real money. But you are amazing for your age, and I am very impressed.
Early on there was some concern about simulated fills with regard to your first system. There was a general consensus that that system could not make money in real trading.
Now you've gone much further and your results show some promise of eventual success. But let me remind you of those earlier concerns regarding simulated fills. Those concerns are always there. I have yet to see a really good simulated fill engine on any mainstream commercial trading platform --but I haven't seen them all by any means. I can tell you that the worst fill engines buy at the bid and sell at the ask-- the exact opposite of real life for most retail trades. In testing an ATS, always confirm that you are getting realistic fills. That is, if you are buying, make sure the bid moves down through your limit price before your simulated order fills. Vice versa for sell orders of course.
Good luck to you. You're going to be a great trader someday, and probably at a surprisingly young age.
