@Dan, Yes it is may be 90% true for Expiry Range. This 90% is based on my last three months observation. So even as per the Statistical theory we need minimum 7 points for the law of averages to work. So my 90% is debatable. May be I will be able to tell you with enough conviction when I have the data for 4 more months
It also acts as the Centre of gravity. That way if nobody knows where the market will go they can ask Mr. MAX Pain for some direction. For example in Aug-13 Series, if you notice the NIFTY movement, you will see how many times it went near 5500 (MAX Pain in Aug-13 was at 5500 for 80% of the days)
6000 - 5508 (08 Aug) - Down 500 points MAX Pain at 5500
5508-5754 (14-Aug) - UP 250 points MAX Pain at 5500
5754 - 5500 - 5308 (20-Aug) 450 points MAX Pain at 5500
5308 - 5504 (21-Aug) - 250 points MAX Pain at 5500
5504 - 5254 (22-Aug) - 250 points MAX Pain at 5500
5254 - 5528 (26-Aug) - 250 points MAX Pain at 5500
5528 - 5119 - (28-Aug) - 400 points MAX Pain changed from 5500 to 5400 to 5300
5119 - 5400 - 5500 - 5579 (03-Sep) - 450 points. MAX Pain changed from 5300 to 5400 and MArket expired on 29-Aug at 5409.
SEP-13 Series MAX Pain was at 5500 and 5600 was also peeking sometimes and so MAX was between 5500 and 5600 to 5579.
So you can see that 5500 was crossed 5 times starting from 01-Aug-13. If somebody was blindly taking a 250 position away from 5500, then he should have theoretically made 1250 points in NIFTY. Market in Aug-13 made around 1900 points and 1250 points out of 1900 is 66%.
So there is something in this MAX Pain.

If you have this data and want to show them, I mean that is fine. I did compare your OI you posted about Nifty with a program I use on probability math and where you had your max pain, I had with other numbers the same range or level/targets. I do not know how the software is build up, but one of the most important data to put in is Vola and time. An other program I use is the Mc Millen calculator. Also not a bad tool to use in combination with OI from options.
As far as my experience goes, for every thing in trading there exist different methods with similar results. If we can combine such tools, we have some times some % more of odds in our favor to look at the market.
Thanks for the chat and have a nice evening

Edit: As I not trade your market live, I only compare tools which I use in my market (CME). So some times it is really interesting to do so and opens a traders mind to other stuff or even seconds the use of some stuff we do use in our trading.
