Original Summary

built this because every backtest i ran on other tools flattered me and i couldnt tell how much. you type a rule in plain english. "buy spy when the 20 day crosses the 50, stop at -8%, hold 10 days". it turns that into a real strategy, runs it on actual us market prices, and tells you what it would have done. then if you want, it runs on a paper desk against live data so you can watch it trade tomorrow morning. the whole point is the fills. it buys at the ask and sells at the bid, never the middle. it can't read a price that didnt exist yet when the signal fired. and it leaves take-profit out of the grade, because a take-profit makes every backtest look better than it will ever trade. free. no card. paper money only, i dont route orders and i never see any broker login. your ai agent can drive the whole thing too if you connect it, which is honestly the part i built it for. being honest about what it cant do: options data only covers feb 2024 to may 2026 so anything outside that comes back empty. daily bars by default. and before june this year the bid/ask on the options store is modelled not measured, which is written on the page. happy to take a beating on any of it.   submitted by   /u/QuanTradin [link]   [comments]
