If you know of an OCD competition, here's my application obsessing over orders, but for those ready, kidding aside, there's some actual useful stuff.
I would wager that everyone can benefit from trying cls_opn_crs() in their own algo to do one thing when an order is opening a position (partially filled) and something different if it is a closing order. Handles both long and short. Took a lot of effort to figure out that complex puzzle. In the bigger picture, probably everyone already knows this is classic overfitting. Incidentally, most of my code is off here using the break, I wanted to beat Luca's result heh.
