Frequently Asked Questions

What is 0DTE options trading?

0DTE (zero days to expiration) options expire on the same day they are traded. SPY has daily expirations, making every trading day an expiration day. These options have extreme theta decay and gamma, creating rapid profit/loss potential.

What is max pain in options?

Max pain is the strike price where option holders would lose the most money at expiration. Market makers may hedge toward this level, causing the stock to 'pin' near max pain. It's most relevant on high-volume expiration days like monthly OpEx.

Is 0DTE trading dangerous?

0DTE options have extreme risk characteristics: gamma is very high (positions can double or go to zero quickly), and there's no time to recover from adverse moves. Use defined-risk strategies like spreads and size positions very small (0.5-1% of account).
