I am trying to identify markets makers within an (options-)orderbook. Of course, this is far stretched, but I was wondering what kind of characteristics / patterns I should look at. I got the following sofar:
- likely, but not necessarily best bid and best offer
- symmetry; a similar amount of contracts bid and offered. This can change due to delay in "reloading"
- changing quote as underlying price/fair value changes
- more likely to quote on odd ticks than round numbers
Below is an example of the orderbook I will be looking at. This represents all the information available
What are additional things I can look at? Thanks in advance,
