Enter your Dollar Risk ($) and Risk Level (stock price where you'd exit). Contracts are sized using Delta + Gamma:
Formula
stockMove = |currentPrice − riskLevel| optionMove = (Delta × stockMove) + (0.5 × gamma × stockMove²) exitBid = max(0, ((ask+bid)/2 − optionMove) − spread/2) lossPerContract = (ask − exitBid) × 100 contracts = ⌈ dollarRisk ÷ lossPerContract ⌉ (min. 1)
Example — TSLA CALL @ ask $2.50 / bid $2.30, Δ=0.50, Γ=0.005, stock $440, risk level $430, dollar risk $100
stockMove = |440 − 430| = $10.00 optionMove = (0.50 × 10) + (0.5 × 0.005 × 100) = $5.25 exitBid = (2.40 − 5.25) − 0.10 → $0 (worthless) lossPerContract = (2.50 − 0) × 100 = $250 contracts = ⌈90 ÷ 250⌉ = 1 contract
⚠ This is an estimation. Actual loss may differ due to wide spreads, delta-gamma moves, and slippage at exit.
