The Greeks measure how the price reacts when something changes. Numbers are per share. The dollar amounts are for one contract. Each small line shows the Greek if IWM moves up to 20% either way, with a dot at today's price.
If IWM rises $1, this call gains about $54. That's like holding 54 shares.
How delta worksEach $1 move in IWM shifts delta by about 0.066. So gains build faster as it rises, and losses slow as it falls.
How gamma worksLoses about $20 a day as time passes. With 7 days left, the loss is speeding up.
How theta worksIf implied volatility rises from 16.5% to 17.5%, this call gains about $14. A 1-point drop does the reverse.
How vega worksIf interest rates rise 1 point, this call gains about $2.52. Rates rarely move that much in 7 days.
How rho worksBuy one contract at today's price, then move the stock, the calendar and implied volatility. The gold line is the profit or loss on that day. The grey line is the result at expiry.
Right now this call is worth about $268 ($2.68 a share). Move the sliders to see how that changes.
