Traderly

Traderly is a browser trading desk for small-cap momentum traders. You can type scanner rules naturally, like "rvol > 3, price < 20," view 1-second candles, and get alerts explaining why they fired. Panels link by color and can pop out to other monitors. It covers US stocks from 04:00 to 20:00 ET, with market data delayed by 15 minutes. Replay is the focus. Missed a breakout? Replay the entire session second by second and trade it again at your own pace without risking money. Reverse splits don't appear as fake runners, and halted stocks never trigger alerts. It is invitation only for now, with 14 days free.
