How does risk-based position sizing work?

Position sizing starts with the maximum dollar amount your account can afford to lose if a stop-loss is hit, then divides that risk budget by the per-share distance between your entry price and stop-loss price to determine the maximum share count.

Example: risking 1% of a $50,000 account

With a $50,000 account and a 1% risk limit ($500 max loss), entering at $100 with a stop-loss at $95 ($5 risk per share) gives a position size of $500 ÷ $5 = 100 shares ($10,000 capital used), alongside 1:2 ($110) and 1:3 ($115) reward targets.

Method

Amount at risk = Account size × Risk %; Position size = floor(Amount at risk ÷ |Entry price − Stop-loss price|). Board lots vary by security; verify the actual lot. 1 means whole shares; no ticker-based guess is made.

FAQ

Why does capital used exceed my account size when risk is only 1%?
When the stop-loss is very close to the entry price (for example 0.5% away), the per-share risk is tiny, so the formula allows a large number of shares whose total purchase cost exceeds cash on hand.
What do the 1:2 and 1:3 target prices mean?
They show take-profit levels where potential gain per share is twice or three times your initial stop-loss distance.
