Is the setup different for crypto vs stocks?

The mechanics are the same; the assumptions around them aren't. Three to think about. There's no session close, so anything that implicitly relied on the day ending — a flat-by-close rule, a daily reset. Has to be made explicit. Liquidity varies by time of day and by venue far more than in equities, so a threshold tuned during active hours can behave differently at 4am. And unattended running is the norm rather than the exception, which raises the importance of hard position caps and time exits. Same tool, stricter defaults.

"Same tool, stricter defaults" is the sentence I'd give every stock trader moving over.

The one I'd add is on the sizing side: if you carry over a fixed dollar-per-trade habit from stocks, your actual risk per trade goes up a lot, because the same dollar buys you a position with a much wider daily range. Easier to size off volatility — pick the dollar amount you're willing to lose, divide by the stop distance measured in something like an ATR multiple, and let the share/coin count fall out of that. Second thing, and people miss it more than the vol: most crypto names move together, so five "different" positions is often one bet at five times the size you intended, so cap the total not just the line item.
