Most of the traders who trade in the futures market end up in losing money in the futures and options market. The most common mistake they make is that they do not analyze the open interest. Open Interest is one of the important parameters while trading in the futures market. If we start working on open interest strategy with respect to volume and price then the traders will have a high probability of success in their trades and also increase their profitability in the futures and options market

Understanding Open Interest with respect to Volume
Open Interest is a statistic unique parameter while trading in futures and options market. Open Interest is the total number of contracts which is presently in existence and is not offset by the closing of trades. Open Interest is different than volume. Volume is the number of contracts traded per day.
If you are buying a future/option then you are opening a position and the person who sold you is also opening a position. The volume is increased by one and open interest would also increase by one. If you sold your future/option to someone else who did not have a position in the market then the volume will increase but the open interest strategy will not change as you have transferred it to someone else that did not have any position in the market earlier.

Open Interest would have decreased if you had sold the position to someone who already had a position in the futures/options market. Since you are closing positions, open interest goes down where as the volume increases by one.
How to analyze open interest data?
Open Interest is important for both stock futures traders as well as option traders. Open Interest shows up where the traders are putting their money in. Therefore analyzing and creating open interest strategy is very important. Let’s analyse the open interest data with the help of a stock in the futures market.
Due to the inherent time decay of premium of options, there are generally large numbers of option sellers in the market. For option sellers, the profit is max the premium value of the option sold, while loss possibility is unlimited. Hence these option sellers are generally very nimble-footed and agile to square off their positions in case of any adverse movement.
Now if we observe in the market, we will find that the bullish players sell put options as they get premium if the prices don’t go below the strike price. Similarly, the bearish players sell call options as they look out for gain if the prices don’t go above the strike price.
If there is high build up in the open interest in any particular strike price of calls and puts of a stock, that means market participants see those levels as potential support or resistance zones, depending on the option being call or put.

Suppose we take up a stock, say Adani Enterprises. We need to examine at which price the maximum open interest is build up and whether in the call or in the put. We can get the option chain data of any particular stock from the NSE website. In the example, the stock price was 123.80. The stock was already in an uptrend as we can see from the below chart below. From this data table we can see that the maximum open interest is build in the call at Rs. 130. Therefore there are possibilities that if Adani goes to 130, call sellers might want to defend their position by creating more resistance around 130 levels. On the other hand, if price breaches the 130 level, the short covering of call writers can push the stock even higher. Let us see, what happened next.

As we can see after breaching the 130 mark, the stock temporarily took support around 130 and eventually moved fast in an upward direction. Two days later we can see, call open interest at 130 has gone down due to short covering, while there has been huge put addition in 130 strike making it a near term support. Also, we can notice that now Adani has huge call build-up at 140 and a150 strike price. Hence if Adani goes higher, price action and open interest behaviour in options around 140/ 150 will be crucial.

Now let us another example:-
Let’s take up another stock, say Axis bank. In the example the stock price was Rs. 523.3. This stock is broadly a range bound stock as we can see from the chart below. From this data table we can see that the maximum open interest in Put side is build in the put at Rs. 500. Therefore there are possibilities that if Axis Bank goes down to 500, put writers might want to defend their position by creating more support around 500 levels. Similarly, we can see very large amount of open interest build-up in 530 and 540 calls. Hence there is a possibility that the stock may remain broadly range-bound in the 500-540 range.
Let us see what happened next
We can see 4 days later that the stock still remained in the range, as could be predicted from OI data analysis. If we look at the open interest data after 4 days we can see that OI remained more or less same in 500 puts and 530 and 540 calls.

Option chain analysis using StockEdge
We can get this data from StockEdge also. Suppose we want to find option chain data of Adani Enterprises in the StockEdge. We can go to the stock sections and in the search panel write the name of the stock, say Adani Enterprises. Then in the option chain tab we will get the call data of the present month expiry. Here in one glance only we can see that maximum open interest strategy is build up at Rs. 130. We can also the put data of open interest of the present month. Here the maximum open interest is build up at Rs 100 but is less than open interest build up Rs. 130. So we can expect an uptrend by analyzing this.

Traders usually give more importance to technical and fundamental analysis and they ignore the open interest analysis which can increase their profitability while trading in the futures market. Volume and open interest are both important aspects which they should equally consider, especially when they look at very short-term supports and resistances. This should add an extra edge to their analysis and increase their profitability.
Could you kindly let me know if StockEdge is available ONLY as an App… or also available
on the PC Desktop. If it is available on the Desktop.. how is to be accessed? Thanks
It is only available in the app version.
Can i compare 3 different CE and PE options on single screen? Lets say the price is 100 and options plus or minus 5 and CE and pe (total 6 including the SP). So CE and PE of 95,10010 105.
You can compare different CE and PE of different tables from the NSE option chain table of that particular stock.
