I'm testing the idea of using option trading data to screen for insider knowledge being implemented.
I don't trade options myself so there are some things that are unclear. Would appreciate some help if someone knows, or if someone know if there is a million people already looking at this
"Open interest" is supposed to show the number of outstanding contracts:
- Can a data provider really provide a full overview of this (legislation?) or is it just a subset of all contracts out there?
- Does it make sense to assume that when a contract is opened, that is being done through a trader (who wants to implement an idea) buys the contract from a market maker? So +1 open call contract implies a positive interest?
I have also tested some things based on the actual trading volume ...
- How much of the trading volume would be traded against a market maker (which would then add/subtract to the number of open contracts by the end of the day), vs just being traded between two traders (which would keep the number of open contracts constant)?
So far I have a screening that looks for sudden extreme spikes in the # open calls, where there are no similar spikes in the # of open puts (or vice versa). Then filtering away some noise.
This will not be a quant trade strategy, just a qualitative screening
