How Traders Can Identify Smart Trading Opportunities Using Option Chain Analysis


The option chain may simply look like a collective data grid at first glance. Most traders simply use it to compare option premiums and never look beyond this data. However, if you know how to use the information in the option chain to your advantage, you can quickly identify smart trading analysis using option chain analysis and find favourable market movements easily.

In this article, we delve into the details of how option chain analysis can be pivotal to identifying support and resistance levels and explore its other lesser-known practical advantages. We also recommend downloading Samco. Its trading app offers comprehensive option chain and F&O insights, making it an invaluable resource for traders looking to implement these strategies.

Identifying Support and Resistance Through Option Chain Analysis

Traditional technical analysis relies on price action to determine the support and resistance levels for a stock or security. However, option chain analysis offers a more sophisticated alternative to identify these critical market points. This approach essentially relies on the collective wisdom of options traders and gives you valuable insights into potential price barriers and breakout points.

Unlike static price-based support and resistance levels, those identified using option chain analysis are more dynamic. They shift as market participants adjust their positions. This fluidity gives you real-time insights into how the market sentiment is evolving and what the potential price inflection points are.

  • Identifying Key Levels Using the Maximum Open Interest (OI)

You can analyse the distribution of open interest (OI) across different strike prices to pinpoint possible support and resistance levels. The strike price with the highest call OI often indicates the resistance level because this is the point at which most traders expect the price to stop rising and reverse. Conversely, the strike price with the highest put OI may be a possible support level where the majority of traders expect the buying pressure will emerge and cause a bullish reversal.

  • Short Squeeze Potential

The infamous GameStop phenomenon that occurred during the pandemic highlighted how short squeezes can fuel rapid price movements. Option chain analysis can help you identify if a similar opportunity is on the horizon. To find a potential incoming short squeeze, look for short positions that are heavily concentrated. For instance, if the stock price breaches a level with significant call OI buildup, it may trigger a cascade of short covering as call writers rush to exit their positions. This, in turn, could accelerate the price rise.

  • Identifying Squeeze Scenarios

To use option chain analysis to identify potential squeezes, you need to track changes in the open interest and trading volume at key strike prices. For instance, say you have identified the resistance level at 24,000 because of high call OI. If this level is breached, there will be a sudden decrease in the call OI coupled with an increase in put OI. This shift indicates that call writers are exiting their positions and put writers are entering the market. It could support further upward movement and signal a squeeze in progress.

  • Applying the Concept to Support Levels

You can also apply the above concept to identify a squeeze scenario triggered by a breach of the support level. If a strike price with high put open interest is broken on the downside, you need to verify if there is a decrease in the put OI and a rise in the call OI at that strike price. This will signal that put writers are leaving the market while call writers are opening new positions. The result of this option chain analysis could essentially tell you that the price may continue to fall.

More Ideas to Harness Option Chain Analysis to Find Strategic Trading Opportunities

Option chain analysis can help you with more than just identifying support and resistance levels and anticipating squeeze scenarios. Here are more ideas that you can use to improve your trading plan with option chain analysis.

  • Insights From Volume and Open Interest

You can use volume and open interest data to assess the level of liquidity in the market and gauge activity levels. High volumes coupled with significant open interest may indicate high liquidity. This potentially reduces the risk of an unsuccessful market entry or exit. Sudden spikes in the volume and OI may also signal emerging opportunities or shifts in market sentiment. Watching for these signs can help you position your trade smartly before the market moves.


  • Implied Volatility as a Predictive Tool

Evaluating the implied volatility (IV) across different strike prices and expiry dates is another important aspect of option chain analysis. It allows you to assess how the market expects the prices to move in the future. Any divergence between the IV of related options can reveal possible mispricing or present opportunities for volatility-based strategies. You can even use this information to adjust your existing positions based on IV changes or set up new trades that capitalise on such volatility divergences.


  • Sentiment Analysis Using the Put-Call Ratio

You can also rely on option chain analysis to assess the prevailing sentiment in the market. The put-call ratio, in particular, serves as a barometer of the market mood. Extreme levels of the PCR can indicate overbought or oversold conditions, so you can use this data to identify contrarian trading opportunities. Also, by combining the put-call ratio with other technical and fundamental indicators, you can obtain a more comprehensive overview of the market sentiment and potential shifts in the mood.

  • Term Structure Analysis

Term structure in option chain analysis refers to the relationship between the implied volatilities of options across different expiration dates but the same strike price. By comparing the IV across different expiries, you get to assess how the market expects the price to move over different maturity periods. You can then align your strategies with these expectations and capitalise on the current sentiment. Term structure in option chain analysis can also reveal how the market feels about upcoming events or regulations.

  • Leveraging Options Greeks

Options Greeks present in the option chain offer a wealth of information about the behaviour and sensitivity of these derivatives to different factors. For instance, the delta can help you assess the probability of an option contract expiring in-the-money. You can use this information to finetune your risk management techniques in each trade. You can also use the Greeks to make smart decisions about position-sizing and risk control — both of which are crucial to optimise profits and cut losses.

  • Finding Arbitrage Opportunities

While pure arbitrage opportunities are rare in efficient markets, relative value trades based on option chain analysis may be possible. So, as you gain more experience in option chain analysis, you can even carefully examine the data to uncover temporary divergences or mispricings between related options. You can then capitalise on these inefficiencies using arbitrage strategies that could potentially generate profits without increasing the risk too much.
