Question: do strategies that find an edge in crypto keep it on US stocks? Most of my library is pure technical analysis, so it's venue-agnostic in code. Markets aren't.

The reality layer you need before results mean anything:

- **Regular hours only**, and reset every indicator at the open: no rolling windows across the overnight gap.
- **Flat at the bell.** No overnight positions in the first version.
- **Short-sale restrictions.** Respect the uptick rule (SSR) on short scouts.
- **Equity cost model.** Per-share commissions and real spreads, not crypto basis points.
- **A universe worth scalping:** liquid, volatile names in a sane price range, with tight spreads. In practice the screen keeps surfacing high-beta themes (space, quantum, AI).
- **Warm up on history.** Bar-based strategies need a couple of hours of 1-minute history at startup, or they sit silent after every restart.

Early read: a lot of crypto-tuned thresholds simply never fire on stocks, and the ones that do need [[The regime gate]] even more.
