I have been trading for a while but I still find it hard to read option chain data. I feel like I might be missing key signals.
The volume and open interest really confuse me. I am unsure how to use them to improve my decisions.
What should I pay attention to when looking at the chain?
Check volume patterns rather than just numbers for spotting real moves.
Volume shows contracts traded in a day. High volume can indicate more reliable price moves. Open interest tells you how many contracts are still open and shows where money is positioned.
Pay attention to unusual volume spikes; if volume is 3-4 times higher than normal, look deeper. The put/call ratio can indicate shifts in market sentiment if it’s too high or low.
Strike prices with the most open interest usually attract prices, especially near expiration. Stick to these basic tools before diving into more complex analysis.
My biggest mistake was ignoring delta values when I started. Lost $800 on AAPL options because I didn’t realize how much the strike price would move relative to the stock.
Now I always check delta first. A 0.30 delta means the option moves about 30 cents for every dollar the underlying moves.
Gamma acceleration near expiration caught me off guard too many times.
Max pain theory helps predict expiration behavior. Find strikes where option writers lose least money; prices often gravitate there.
• Track unusual option flow alerts
• Monitor skew between puts and calls
• Watch for block trades over 1000 contracts
Dark pool activity affects chains before stock moves.
Focus on the bid-ask spread first because wide spreads can eat into your profits quickly. When the spread is tight, there’s usually good liquidity.
Time decay becomes crucial as expiration approaches. Options lose value faster in the final days, so factor that into your timing.
Compare implied volatility across different strikes. If one strike has much higher IV than others, there might be specific news or events affecting that level.
