You picked a strike because it “felt” safe — maybe 10% out of the money, decent premium, three or four weeks to expiry. Then price ran straight through it in two days flat, and your “safe” trade turned into a stressful one. If you’ve sold options for more than a few months, this has happened to you. Most strike price selection isn’t really a plan — it’s a guess dressed up with a delta number. A proper options selling strategy doesn’t guess. It looks at the chart, finds the levels where price has struggled before, and sells there on purpose.
Why Picking Strikes by “Feel” Keeps Burning You
Here’s what usually happens. You open the option chain, sort by premium, and pick something that pays well without looking too scary. That’s not a strategy — that’s shopping by price tag.
The problem is that every strike sits on a chart whether you look at it or not. Price has a memory. It’s bounced off certain zones before, and it tends to hesitate there again. Ignore that, and you’re selling into a level price has already broken through twice this year.
So what does “looking at the chart” actually mean in practice, beyond the vague advice you’ve probably already heard?
What Support and Resistance Actually Tell You
Support and resistance are just zones where buying or selling pressure has shown up before. Support is where price has stopped falling more than once. Resistance is where it’s stopped rising more than once. Nothing mystical — just a record of where the crowd changed its mind.
For an option seller, that history is gold. If you’re selling a put, you want your strike sitting below a support level, not floating in open air where nothing has ever stopped price before. If you’re selling a call, you want your strike above a resistance level that’s actually held.
This is the core of support and resistance trading for income sellers: you’re not predicting where price will go. You’re identifying where it’s historically had trouble going — and letting the option premium pay you for that observation. Simple in theory. So why doesn’t everyone trade this way already?
The Support & Resistance Strike Selection System
Because most traders never turn it into an actual process. They eyeball a chart once, feel good about it, and move on. Here’s a tighter checklist to run before you sell anything:
- Pull up a daily or weekly chart and mark the two or three most obvious support and resistance zones — the ones price has touched at least twice.
- For puts, look for a support zone with room underneath your intended strike — not a strike sitting right on top of it.
- For calls, do the same thing above a resistance zone.
- Check how recently that level was tested. A level from years ago carries less weight than one tested last month.
- Confirm the strike still pays a premium worth the risk — a “perfect” level with no premium isn’t a trade, it’s a chart exercise.
Notice what’s missing here: no fixed delta rule, no “always sell 30 days out.” The level comes first. The mechanics fit around it. That’s a different order of operations than most beginners use — and it changes how a trade actually plays out.
A Worked Example
Say a stock is trading at 148. Looking back over the last several months, it’s bounced off the 138–140 zone three separate times — each time buyers stepped in and pushed it back up. That’s a real, tested support zone, not a guess.
You sell a put at the 135 strike, 30 days to expiration, collecting 1.40 in premium. Your strike sits a few points below the tested zone, giving price some room to wobble without threatening your position. Two outcomes tend to play out from here:
- Price holds above 138 through expiration, like it has before. The put expires worthless, and you keep the 1.40 — roughly 1% return on the capital at risk for the month, without ever needing to be right about direction, only about the zone holding.
- Price breaks below 138 anyway — support zones aren’t guarantees, they’re just the best evidence you had. Now you’re either assigned shares at 135 (effectively 133.60 after premium) or you manage the position, depending on your plan going in.
Compare that to selling the 143 strike instead, just because it paid more premium. That strike sits inside the danger zone, not below it. You’d be collecting extra income in exchange for selling exactly where price has already proven it can go. That’s the trade-off most sellers make without realizing it.
The Catch: Levels Aren’t Guarantees
Now, you might be thinking — support breaks all the time, so what’s the actual edge here? Fair point. A support zone is a probability marker, not a wall. Stocks blow through “obvious” levels regularly, especially around earnings or broad market shocks.
The edge isn’t that price can never reach your strike. It’s that you’re stacking the odds by selling where price has historically needed real pressure to reach — instead of a random point in space. Over many trades, that difference in strike quality tends to matter more than most beginners give it credit for.
The other catch: levels shift. A support zone that held for months can turn into resistance once price breaks below it. This is one more reason strike selection isn’t a “set it once” decision — it’s something you check trade by trade, not something you memorize forever.
The Takeaway
Stop picking strikes based on premium size or a delta number alone. Before your next trade, mark the real support and resistance zones on the chart first, then place your strike a comfortable distance beyond them — let the level justify the trade, not the other way around. Do this consistently, and strike selection stops feeling like a guess and starts feeling like a process you can actually repeat.
