TradeBeagle now has three scanners: Opening Reversal and Short Reversion for stocks, plus Overnight Crypto beta events. The stock examples below illustrate chart-review principles; crypto events are descriptive and ordered by bar time, not ranked by strength. Review crypto liquidity, exchange pricing, and risk separately. See the day/night scanner schedule.
A common mistake is treating a strong-looking scanner flag as a reason to size up. It isn't. Two separate decisions are at play in any trade — whether the setup is valid, and how big the position should be — and keeping them separate is most of what disciplined risk management actually is.
Size comes from your stop, not your conviction
The standard approach works backward from risk, not forward from excitement. First, decide how much money you're willing to risk on the trade — a fixed dollar amount or a percentage of your account, whatever fits your own plan; that number isn't prescribed here. Second, find your stop on the chart — the price level where the setup is simply wrong. Position size falls out of those two numbers: risk amount divided by the per-share distance to your stop. A tighter stop supports a larger position for the same dollar risk; a wider stop means a smaller one.
The stop distance decides the size, not how confident the setup looks. Wider stop, smaller position; tighter stop, larger position — same dollar risk either way.
Why “the scanner flagged it” isn't a sizing input
The scanner's job stops at flagging an unusual pattern — an abnormal opening range, or a seven-timeframe stack. It has no visibility into your account size, your existing positions, or your risk tolerance, the same point the morning workflow article makes about the decision step that closes out every trade. Sizing up because a flag looks especially strong is exactly how otherwise-disciplined risk plans quietly break down over time.
Key takeaway: how exciting a setup looks is not a sizing variable. Only your predetermined risk amount and your stop distance are.
A rule that travels well
Decide your position size mechanically, from the formula, before you let yourself react to how promising the chart looks. Precommitting to the math is what keeps a good setup from turning into an oversized bet on a morning when everything feels obvious — which, in hindsight, is usually the morning it wasn't.
