What is GEX (gamma exposure)?

It estimates how much dealers must buy or sell to stay hedged as price moves, which tells you whether moves get dampened (positive gamma) or amplified (negative gamma).

What is max pain?

The strike where the total value of options expiring is minimized, often a magnet into expiration. The guide above explains how to use it.

When should I upgrade?
