Is there a way to filter out European Options only in the on demand Time Series request.
Currently the way I use to get options data is to get options chain using historical chain request, and then use the RIC I get the request settlement price.
However, for Crude Oil contract only, CME CL, I get more than 100,000 contracts, which I believe contain all kinds of option with CL as underlying asset. Is there a way to filter out just European Options rather than get all kinds of Options.
Also, is there a way to set a limit of range for strike price based on ATM price when we get the RIC. Really surprised that Reuters provide strike that are really deep in the money and out of money which would not have any trade during the whole year.
What do you mean by "European options" ?
There is no such filter on data extraction requests, so you would first have to filter your RIC list using the results of a T&C request. Adding the T&C request brings some overhead, so following this route will only be effective if the following data request is for a large number of fields or a big date range.
As explained in this separate thread, there is no possibility to limit the results to options where the strike price is around the ATM price (a definition of "around" would be quite subjective by the way).
It might seem surprising that we provide strike prices that are really deep in the money and out of money, but that is simply because we deliver all the data from the exchanges. You can consider that as a "gold copy", which entirely represents and respects what market participants did, without any bias. Data filtering must be done by the consumer, following his own rules.
