How to read the chart

The solid line shows the value before expiry. The dashed line shows the first expiry date. Green is profit. Red is loss. The orange ring is the result that week.

Read the true maximum loss above the chart. Check each leg's before using a basket.

What time changes

An option loses its as expiry gets closer. Keep the index still and move the time slider. A later expiry still has time left when the front leg settles.

When it fits and when it does not

Choose the shape for the move you want to understand. A spread can cap both gains and losses. A sold option can leave a large loss. More legs do not make a basket safe.

Common mistakes

Check every leg, its ratio and its expiry. Finishing does not mean you made a profit. Subtract the premium and charges. A capped chart does not cap an unbounded loss.

Charges are shown separately. An option held to expiry is charged differently.
