here's an image - shows some testing I'm doing on the QQQ ETF for the Bear Long sub system - you can see I have a test running on the right - still almost 3 hr left. Hopefully I can finally finish this one system today - been messing with it since weekend.  This is ONE sub system on one ETF - the point is, it's gonna take a while guys to complete these -though the Bear long is a real bitch to backtest, there's some weird complicated math in one of the indicators that Tradestation struggles to run - puts TS on it's knees basically, and so even small backtests can take hrs.

anyway the process I go through is pretty methodical. I test tons of different parameters, and I do them in parts. First testing entries, doing multiple versions. I don't just pick the ones with the highest profits -I focus a lot of a higher profit factor and draw down - I look at every past trade to see if there was any big gotchas. I make multiple versions and try and decide between like 10 versions. Then I test things like hold conditions, scale ins. At the end I have to try and pick the best version maybe out of 20 versions. It's a VERY tedious process, my brain starts to hurt and I need to take breaks lol
