Instead of diving into the topic I will like to cover basics first. Lets first understand meaning of the terms Long and Short. Note You can also download Open Interest analysis excel sheet to make most of out of the chapter. The link is provided at the end of the chapter.

You have to Buy and Sell Futures and Options Monthly. For bank Nifty it is also weekly. When a person buys a derivative then but not sell it then the open interest is 1. The term open interest signifies number of derivative contracts open in market.
A contract is open if it is Bought only or Sold only. That is you have Bought a contract but have not sold it. You can also sell a contract but not buy it. In both conditions contract is open and open interest increases.
The contract is closed if it is bought and sold both. So open interest at a time shows number of contracts open or sold at a period of time.
What is Long?
Long or long position is bullish. It means person is expecting the stock prices to go higher. So they are buying the stock first with a view to sell it later.
What is Short?
Short position is bearish. It means person is expecting the stock price to go lower. So they sell the stock first with a view to buy it later.
Understanding Long and Short Positions
For Long position People buy at low price and sell at high price to make profit. The concept is same for Short as well. People are selling at high price and will buy at lower price. The sell action and buy action occurs at different points. This is the only difference.
For Short sell occurs at first high price and Buy occurs last at low price. The Sell occurs first and then Buy. For Long Buy occurs first at low price and Sell occurs last at high price. The Buy occurs first and sell occurs.
Understanding this basic difference is key to next part of article.
Long buildup means more people are expecting the prices to go up and creating Long positions. You can simply look at Price and Open Interest to get an idea. If the price and Open Interest goes up then it is Long buildup.
This signifies more traders are expecting the prices to go up.
Short buildup means more people are expecting the prices to go down and creating Short positions. You can simply look at Price and Open Interest to get an idea. If the price goes down and Open Interest goes up then it is Short buildup.
This signifies more traders are expecting the prices to go down.
Long Liquidation/ Long Unwinding
Futures and Options are one month affair as mentioned above.The concept remains the same. People who have Long positions will have to sell the positions.
The open interest will decrease if Long positions are sold off. The price will decrease and Open interest will also decrease. This signifies Long Liquidation or Long unwinding.
Note Long Unwinding causes the prices to go up.
If you understood concept of Long Liquidation then it is similar to above one. People having short position will have to Buy the positions. The open interest will decrease if the short positions are covered. The price will increase and open interest will decrease. This signifies Short covering.
Note short covering causes the prices to go up.
You can use above interpretation with Nifty Open Interest graph to decide whether to Buy Call option or Put option.
The Long Buildup and Short Covering at a particular price shows price will go up. In this case you can buy the call option.
The Long liquidation and short buildup shows the price will go down. In this case you can buy the Put option.
Not this is the strategy looking at the Open Interest. You should combine this with Global market condition and Technical to make it loss proof.
