Be a Bookie

Most retail option buyers behave like lottery players: small stakes, low probability, occasional big payouts. The other side of every option ticket is the seller — and sellers, statistically, look a lot more like bookies than gamblers.

A bookie sets odds, takes wagers from both sides, and keeps a small edge on every line. They lose individual bets all the time. What they care about is expected value over many tickets.

Option sellers play the same game.

• They collect a known premium up front.
• They pay out only when a specific contract finishes in the money.
• Over hundreds of trades, the premium collected slightly exceeds the payouts — that's the implied-volatility-risk-premium edge.

This article walks through the mechanics of running an "options book": how to size positions, when to roll, how to recover from a loss, and how to think about variance over a year of selling.

The reality of selling options is that you will lose on individual trades — sometimes badly. The job is not to avoid losses but to keep them small enough that the long-run premium-collection edge wins.
