How position sizing works
The single biggest difference between traders who survive multi-year market cycles and traders who blow up is position sizing. The math is simple: decide a small fraction of your account (usually 1–2%) you're willing to lose on any one trade. Pick an entry and a stop-loss. Divide the rupee risk budget by the per-share risk (entry minus stop). That's the maximum number of shares you can buy and still keep the blow-up bounded.

Frequently asked
What is position sizing and why does it matter?
Position sizing is the decision of how many shares to buy on a given trade. The standard rule is to never risk more than a fixed percent of your account on any single trade — typically 1% to 2%. If you risk 1% per trade, you can be wrong 50 times in a row and still have over 60% of your account. If you risk 10% per trade, ten losses can wipe you out. The math is brutal.
How do you calculate position size from a stop-loss?
Risk amount = account size × risk %. Per-share risk = entry price − stop-loss price (for a long position). Position size = risk amount ÷ per-share risk, rounded down to a whole share. This formula guarantees that hitting your stop-loss costs you exactly your chosen risk amount — no more, no less.
What are R-multiples and why use them?
R is the per-share risk (entry − stop). An R-multiple is a profit target expressed as a multiple of that risk. 2R means a target where the profit equals 2× the risk you took; 3R means 3×. Thinking in R-multiples lets you compare trades fairly — a winning trade that returned 2R was twice as good per unit of risk as one that returned 1R, regardless of the underlying stock price.
Does this account for NEPSE's broker commission?
No — the sizer computes the gross position. NEPSE's broker commission is small (~0.3%) relative to typical stop distances (usually 2–5%) so it doesn't materially change the position size. For tighter stops, factor commission into your stop price (move it slightly wider) or use the Capital Gains Tax calculator after the trade to see the net result.
