The contract you are about to buy, in numbers you can verify against your own screen — and the five things that actually take the money, answered before you are in it.
Reads nothing · places nothing
Everything here is arithmetic on what you typed. Nothing is fetched and
nothing is placed. If the numbers do not match your broker screen, your
broker screen is right and one of the inputs above is wrong.
Time decay is shown as time value divided by days left — the straight-line
figure you can check tomorrow, not a model theta you cannot. Real decay
accelerates into expiry, so on a short-dated contract treat this as the
optimistic case.
