I have been working on systems with tradestation for years already, but the things that work in my discretionary trading on the minidow and seem so simple are hard to code, or at least they never seem to work when coded (maybe not properly). The result is that if I am not in a good state of mind, I lose, because I haven't coded my ideas, and the recipe for a good trade. On the other hand, after months of work, I always end up with a very elaborate system, with a lot of inputs, which is not what I originally had in mind, and, something I don't even understand, trust or that I can use, even if it seems to make money on paper. There are just a few simple concepts that I consider when trading and that I can't code in a simple way which at the same time will show good results when tested, such as: - buy rises in an uptrend, sell declines in a downtrend, buy/sell breakouts in a range - decide the trend/range based on a 30 minutes graph - reversals tend to happen at 9.35, 10, 3.30, 3.55. Can anyone help me, work with me or give me advice?
