Support and Resistance for Options Traders: Where to Place Strikes
Support and resistance levels are the most heavily over-discussed and under-respected concept in retail trading. The honest version: they are zones where supply and demand have historically clustered, and they matter — but only as one input among several, never as a standalone trade trigger.
For options, S/R levels matter most for strike selection. Selling a put below a strong support zone stacks two probabilities in your favor: the option is OTM, and the price level itself has historical buying interest. Selling a call above a strong resistance zone does the same in reverse. The premium collected does not change based on the level — but the probability of the trade working does.
Common misuse: drawing dozens of lines on every chart and treating each as meaningful. Real S/R is rare — typically two or three significant levels per timeframe per stock. The lines that have been tested multiple times and held are the ones that matter; the rest are noise. Less is more in level identification.
Frequently Asked Questions
How far below support should I sell a CSP strike?
Common practice: at or below the next major support level, with a delta of 0.20–0.30. Deeper OTM strikes give more buffer but collect less premium.
Are moving averages reliable as support and resistance?
The 50-day and 200-day MAs are watched widely enough to act as self-fulfilling levels in liquid names. Less so in low-volume tickers.
