Trading options without relying on traditional price charts might seem counterintuitive to many, but there exists a strategy that simplifies decision-making by focusing on the premiums of at-the-money (ATM) options and changes in open interest (OI). This approach allows traders to determine whether the market is likely to be directional or non-directional, guiding their strategies accordingly.

When the market is directional, traders can benefit from setups that profit from buying options. However, if the market is expected to be non-directional, avoiding directional strategies can save money, while deploying non-directional strategies can earn profits. The challenge lies in accurately predicting whether the market will be directional or non-directional. The good news is, you only need to track two key indicators to make this determination.

The first key indicator involves analyzing the premiums of ATM options, known as the straddle chart. Many traders, especially sellers, are familiar with this concept, but it is equally valuable for buyers. By applying a simple indicator like the Volume Weighted Average Price (VWAP) to the straddle chart, traders can gauge the momentum in the market and decide whether to adopt a directional or non-directional approach.

Let’s delve deeper into how this works. Imagine you are trading Bank Nifty, an index in the Indian market. Instead of looking at the index chart, you focus on the premiums of the ATM call and put options, combined as a straddle. For example, suppose the combined premium of the call and put options at the strike price of ₹47,600 at 9:20 AM is ₹421, and the VWAP at that time is ₹428. This close proximity suggests that the market is near equilibrium, indicating a lack of strong momentum.

To understand the market movement, observe the price action of the call and put options individually. If the call option’s price is falling, it signifies that the market could either be moving sideways or downward. Conversely, if the put option’s price is also falling, it indicates that the market could either be moving sideways or upward. When both call and put premiums are dropping, it signals a sideways market with little to no momentum.

This information is crucial because it helps traders decide their strategy without needing to analyze the traditional price chart. If the market shows signs of being non-directional, as indicated by falling premiums in both call and put options, it’s a cue to avoid directional strategies that rely on market trends. Instead, traders can focus on non-directional strategies like straddles or strangles, which profit from time decay and volatility changes rather than price movements.

The second key indicator is the change in open interest (OI). Significant changes in OI can signal impending market moves. For instance, a large increase in OI for call options at a specific strike price could indicate bullish sentiment, suggesting that traders expect the market to rise. Conversely, a significant increase in OI for put options might indicate bearish sentiment. Monitoring these changes helps traders anticipate potential market shifts and adjust their strategies accordingly.

Combining the analysis of ATM premiums with changes in OI provides a comprehensive view of the market’s potential direction. This method bypasses the need for traditional price charts and allows traders to make informed decisions based on market sentiment and momentum.
For example, imagine that at 9:20 AM, the combined premium of Bank Nifty’s call and put options is ₹421, with the VWAP at ₹428. Throughout the day, you observe that both the call and put premiums are consistently falling, indicating a sideways market. Simultaneously, you notice a significant increase in OI for ATM call options, suggesting bullish sentiment. Based on this information, you might decide to hold off on deploying a non-directional strategy and wait for more concrete directional signals.

This approach not only simplifies trading but also enhances the accuracy of market predictions. By focusing on these two indicators – ATM option premiums and changes in OI – traders can effectively navigate the complexities of the market without relying on traditional price charts. This method is particularly useful for option sellers who trade throughout the day and need to make quick, informed decisions.

Momentum in financial markets refers to the tendency of an asset’s price to continue moving in its current direction. If the market is falling, this means there’s a strong downward trend. In options trading, a spike in the put options signifies increased buying interest in puts, suggesting that traders expect further declines. For instance, if the combined premium of a particular option was 421 and then jumped to 550 within the next five minutes, it indicates significant selling pressure in the market. This rapid increase in the premium points to a strong bearish sentiment.

On a typical trading day, if you observe the market price below the VWAP (Volume Weighted Average Price), it signals that the selling momentum is dominant. In such scenarios, it’s advisable not to initiate buying positions. Selling or taking short positions can be more profitable under these conditions. For example, if the market was at 421 or 428 at 9:20 AM and remained below VWAP throughout the day, it would indicate a consistent downtrend. By adhering to the strategy of selling when the price is below VWAP, traders could potentially avoid losses and capitalize on the downward momentum.

In contrast, if the market is above the VWAP, caution is necessary. An upward position might imply that either call or put options are actively traded. If you are holding a neutral position by selling both calls and puts (a straddle), the market being above VWAP could lead to stop-loss triggers due to increased volatility. For instance, if you sold straddles from 9:20 AM to 11:55 AM and observed the combined premium falling from 521 to 358, you could have earned a profit from the premiums melting.

Understanding the backend logic of these movements is crucial. Implied volatility (IV), calculated based on at-the-money options, plays a significant role. The at-the-money IV provides a benchmark for overall market volatility. If the IV decreases, the premium for the options will also decrease. This melting of premiums benefits sellers, as lower volatility typically leads to less aggressive price swings. Monitoring whether the premiums of both call and put options are decreasing while the market is below VWAP can reinforce the decision to maintain selling positions.

For a practical approach, traders can observe the IV of at-the-money options, as this reflects the market’s overall sentiment. Selling strategies like straddles (selling both calls and puts) become more manageable with a clear understanding of IV and its impact on premiums. If the at-the-money IV is decreasing, indicating lower volatility, premiums will melt, favoring sellers. As a result, maintaining a selling strategy while the market is below VWAP can be highly profitable.

Active traders should also consider the concept of “change in open interest (OI).” This metric indicates the number of outstanding options contracts and can provide insights into market dynamics. For instance, on April 3rd, observing the change in OI for Bank Nifty from 9:15 AM to 7:30 PM could reveal shifts in market sentiment. If there was a significant increase in call OI but a decrease in put OI, it would suggest a bullish sentiment, while the opposite indicates bearishness.

In the world of options trading, understanding and interpreting the change in open interest (OI) is crucial for making informed decisions. Let’s delve into how the change in OI, specifically in the context of call and put options, can indicate market sentiment and help traders like you strategize effectively.

Imagine you’re a seller who needs to open contracts worth Rs. 500 crores. When you sell call options, this action adds to the open interest. If previously, other traders had shorted call options worth Rs. 1,000 crores, and it has now decreased to Rs. 200 crores, this fluctuation is a significant indicator of the market’s direction. The change in OI shows the net change in contracts traded, which traders closely monitor to predict market movements.

When analyzing OI, it’s essential to consider whether it has increased or decreased for the day and in which direction. An increase in OI for put options typically suggests that the market is expected to rise, as sellers are betting against a market decline by selling puts. Conversely, an increase in OI for call options indicates a bearish sentiment, as traders are positioning themselves for a market drop by selling calls. This is where the put-call ratio (PCR) comes into play. The PCR is calculated by dividing the change in OI for put options by the change in OI for call options. A higher PCR, such as 1.4, signifies that more puts are being sold than calls, indicating a bullish market sentiment.

To stay ahead, traders need real-time data. For example, if at 10 AM you observe that there are 93 lakh puts and 60 lakh calls, with the volume-weighted average price (VWAP) around Rs. 30-31, it suggests a sideways market. This insight can help you decide your trading strategy. If the OI for puts is higher than for calls, you might consider selling in a ratio that reflects this dominance. For instance, selling two put options for every call option, assuming a sideways to bullish market.

Monitoring OI changes throughout the day is crucial. Suppose at 2 PM, you notice that the put side’s dominance has waned, indicating a potential market shift. As a conservative trader, you might then adjust your position by closing out the extra puts sold earlier, thereby mitigating potential losses.

Let’s consider a scenario where the market is at 47,600 points. Based on your strategy, you decide to sell the 47,400 puts and 47,800 calls, each priced around Rs. 95 at 10 AM. Setting a stop-loss (SL) at 35% of the price means you will exit the trade if it reaches approximately Rs. 130. Throughout the day, if the SL is not hit, you continue to monitor the market. At 2 PM, if the data shows a shift in put dominance, you close the extra put positions. By the end of the day, if the puts are priced at Rs. 84 and calls at Rs. 62, your strategy yields a significant profit despite minor fluctuations.

In this example, the put options sold at Rs. 95 are closed at Rs. 84, giving you a profit of 10 points. Similarly, the calls sold at Rs. 135 are now at Rs. 62, providing a 50% decay and a profit of 73 points. This consistent approach of aiming for a modest profit of 50-60 points per trade, rather than expecting unrealistic returns, ensures steady gains.

To optimize this strategy, it’s advisable to wait for about 30 minutes after the market opens at 9:15 AM. This waiting period allows the OI and price data to stabilize, providing a clearer picture for analysis. If the OI data supports a sideways market, position your trades accordingly. If there’s a significant disparity in OI, like 1 crore on one side and 50 lakh on the other, adjust your strategy to leverage this imbalance.

Trading in the stock market can be simplified with a passive strategy, especially if you automate certain processes. For a passive trader, investing becomes easier by focusing on two daily tasks: monitoring your investment and executing a straddle or strangle strategy. By incorporating a VWAP (Volume Weighted Average Price) indicator through an algorithm, you can automate your trading decisions. The key is to set your algorithm to trigger based on the closing candles. If the combined candle closes below the VWAP, the trade should be exited. This automated approach allows you to relax and let the algorithm manage your trades. However, if you incorporate changes in Open Interest (OI) into your strategy, manual intervention is required since these two elements—VWAP and OI—cannot be mixed in an automated system. Therefore, for passive traders, it is advisable to avoid using changes in OI.

This concept might be new to many, though experienced traders are likely familiar with reading straddle charts in this manner. For those new to this approach, it’s an excellent way to streamline your trading strategy.
