Most options blow-ups are not caused by bad math. They are caused by behaviour — too much size, the wrong stock, a trade nobody should have put on. So before any tactics, here is the philosophy this whole site is built on. It is deliberately narrow, and that is the point.
The Options Bench house rules
- Cash-Secured Puts first. Start with the one strategy that is fully backed by cash and easy to reason about.
- Sell only what you can cover. Never sell an option you could not honour — cash for Puts, shares for Calls.
- No Naked Calls. Selling a Call without owning the shares has theoretically unlimited loss. We never do it.
- No 0DTE selling. Same-day-expiry options swing violently near the close. Beginners stay away.
- Only stocks you would own. Sell Puts only on companies you would be happy to hold for years at the strike.
Why these rules
Cash-Secured Puts first because they are the one strategy where the worst case is simple and survivable: you buy a stock you already wanted, at a price you chose. Everything else — the Wheel, spreads, Covered Calls — builds on understanding that one trade well.
No Naked Calls, ever. Selling a Call without owning the shares means that if the stock keeps climbing, your loss climbs with it — with no ceiling. Picture selling a Call on a $50 stock that gets taken over overnight and jumps to $90: you’d have to buy the shares at $90 to hand them over at the strike, a loss far bigger than the premium you collected. No premium is large enough to justify an open-ended risk like that.
No 0DTE selling — that is, options that expire the same day. Their price whips around violently in the final hours, so a quiet morning can flip to a brutal afternoon in minutes. It is a coin-flip dressed up as income, not a beginner’s trade.
Only stocks you’d own ties it all together: the worst case of a Cash-Secured Put is being handed the shares, so if that would upset you, you picked the wrong stock in the first place.
The part nobody warns you about: yourself
The hardest risk to manage is psychological. Three traps catch almost everyone:
- FOMO. A stock rips and you feel late, so you sell a Put far too close to the price for a fat premium. The premium is fat because the risk is high.
- The "easy income" trap. After a string of wins, selling feels free, so you size up — right before the trade that gives it all back.
- Panic. A red day arrives, you abandon the plan, and you turn a temporary paper loss on a stock you’d own into a permanent realized one.
The rules above exist to make these mistakes hard to commit. Consistency, not excitement, is the entire edge. When in doubt, size down — and let the position-sizing tools keep you honest. The trading psychology guide goes deeper on all six common traps and how to counter each one.
Common beginner mistake
Chasing the premium instead of choosing the stock. Beginners scan for the biggest yield and sell a Put on a company they’ve never researched. Pick the stock you’d own first; let the premium be whatever it is.
Key takeaways
- The approach is narrow on purpose: CSP-first, defined-risk-first, own-the-stock-first.
- Two hard bans — no Naked Calls (unlimited risk) and no 0DTE selling (gamma roulette).
- Most blow-ups are behavioural; the rules exist to make FOMO, over-sizing and panic harder.
