Ask a new trader about their strategy and they'll describe entries. Ask a trader who's survived five years and they'll describe risk. Position sizing — how much you put on each trade — matters more to your long-term outcome than any entry signal.
Risk per trade, not share count
Decide what you're willing to lose on a trade (commonly 0.5–1% of your account), then let that and your stop distance determine share size — not the other way around. If a stock is $20 with a stop at $19 (a $1 risk per share) and you'll risk $100, you buy 100 shares. The entry doesn't set the size; your risk does.
Stops are non-negotiable
A position without a predefined stop is an open-ended bet. Define the stop before you enter, based on structure (below the setup's invalidation point), and size so that hitting it costs only your planned risk. TradeScaner ships every pick with an exact entry, stop, and two take-profit targets for this reason.
The max-daily-loss circuit breaker
- Set a hard daily loss limit (e.g. 2–3 trades' worth of risk).
- When you hit it, you're done for the day — no revenge trades.
- This single rule prevents the catastrophic days that end accounts.
Why it compounds
Good sizing turns a mediocre 40%-win strategy into a survivable one and a great strategy into a durable one. Bad sizing blows up even a profitable edge. Prove your process on paper trades first, size small, and scale only once the track record is real.
Nothing here is financial advice — trading involves substantial risk of loss. The point is simply that risk management, not entries, is where consistency comes from.
