I'm using the CacheControl object in the REDI API to subscribe to trade events. There are 5 documented values of the "Action" parameter:
My question is: What is the purpose of the 'Delete' and the 'Release' actions? Why would I want to delete an order from the trade history? I can look at OrdStat to get the status of the order, to know what is active/completed/canceled, etc. So why would REDI tell me to delete it?
Also, what does 'Release' mean in this context?
Do you have further documentation on the "Action" parameter or the CacheControl object? There is very little context provided in redi_api_specification_6.pdf.
