<<The above is not correct but the idea is there. OI is the number of open contracts. It matters not if the contract is short or long.>> At the risk of totally confusing the fellow who posed the initial query, what you have suggested is just an elaboration of my perhaps terse response. long = buying , short = writing . Also, the distinction between new vs. prior positions needs to be emphasized. Let me know if further elaboration is needed. :)

Glenn and Santhosh, my question(open interests) continues: Hey thank you guys. I got the key of the answer, which is whenever you open a new position(regardless long or short), it increases the OI. Now I got another related question: Often time, when a stock was depressed, people would start to blame MM to hold the price down becasue of high call/put OI ratial, ..., which makes sense in terms of calculation except that realisticly I don't think it is likely for a stock like COMS. Now according to your answer, both long and short will be contributing to OI, e.g. Fred long 5 contract call and Joe writes 5 calls, the OI will increases 5+5=10. Of course, if the MM conspiracy is true, they will only be interested in killing Fred's 5 long. Joe's 5 short will not hurt them at all if the stock price shoots up. By giving that, it is still true that the total OI is some reflection of MM's intention regarding the stock movement? What if the OI are all from call writer? Please help. Thanks in advance.
