How this works

Fixed-fractional risk. Dollar risk = account × risk %. Per-share risk = absolute distance from entry to stop. Shares = floor(dollar risk / per-share risk).

The R-targets show where 2× and 3× the per-share risk lands on the other side of entry. Useful for sketching where partial exits go before you ever look at a chart.
