Risk Management

Range-Based Position Size Calculator

Size a trade whose stop sits on the far edge of a known support/resistance range (rather than a multiple of ATR). Enter account size, risk per trade, the price width of that range, and a point value, to get the number of shares or contracts to trade.

Educational tool only, not financial advice. Position sizing does not eliminate loss; markets can gap beyond your stop. Check it against your own plan and risk rules before you trade it.
