Options Essentials: Greeks, IV and Payoffs

Three steps into options pricing: what each Greek measures in dollars, how implied volatility becomes an expected move, and how to read a payoff diagram.

New to trading? Work through Trading Foundations first — this path assumes you can already size a position from a stop.

What you’ll be able to do

  • Read delta, gamma, theta and vega as daily P&L rather than abstract sensitivities
  • Convert implied volatility into the move the market is pricing
  • Cross-check an IV number against the straddle price
  • State the maximum loss on a position before opening it

The path

  1. Attach a dollar figure to each Greek on a real position.

    Practice

    Read the Greeks on a 30-day at-the-money call, then shorten it to 7 days and watch theta.

    Open the Option Greeks calculator →
  2. Turn an IV percentage into the range an option is pricing over a set number of days.

    Practice

    Find the 30-day expected move at 20% IV, then double IV to 40% and compare.

    Open the Expected Move calculator →
  3. Compute the worst case on a short put before the position is opened.

    Practice

    Chart a 95-strike cash-secured put collected for $2.50 and read the breakeven.

    Open the Options Profit calculator →

Start with step 1

The steps build on each other — the position sizing in step three depends on the stop placement in step two.
