I couldn't find the reference to IOI's (indications of interest) on the pdf... I did find this, which gives hints of the formula... Buyers and Sellers are probably refering to the depth of market field which indicates the number of orders sitting in the queue. Volume could be either the executed volume, or the volume from the order book. You take this 2 to form a ratio... Who knows how they relate this ratio to price. it should be easy to reverse engineer this if you have a bloomberg terminal with the indicator so that you're able to compare it to your results from raw data.
Commitment of capital, may be contracts * face value of the contract? (e.g. taking the globex price?)
Thanks again for your response! I am convinced that this is the depth of the order book and not the executions. Yes, the next step is to look at the raw data and try to figure out. Good thing about bloomberg is that they have a vast datawarehouse and they save bids and ask sizes going back to 240 days!! That is they save each second the bids or asks change. It is not the face value of the contracts. This indicator is all about buyers and sellers from the depth of the market also known as order book. How they calculate this is what i am trying to figure out. I am pretty sure it has to be a moving average. I was interested in finding out what other people thougt of it after reading this user manaul.
