No specific advantage in new wine when stored in old bottle. When everyone moves to REST companies do find lost out.treand2009-We do not offer a REST API. What is the advantage in using them?
REST is stateless, like html, no two way communication management.Is REST two way with respect to market data or only for order entry?
not sure how these rest apis are implemented but they should accept batches of orders, so post one batch consisting of 200 orders... takes a second. rest api gets the batch and submits each order takes a second. continually poll the api to see if you're filled.IB, as well as tdameritrade, etrade, have rest api for trading. anyone has experience using them? is it possible to submit 200 orders in one minute and track if the orders are filled or not?
How about WebSocket?REST is stateless. So you would need to POST the orders and either get the results back as a response (unlikely since orders need to be worked), or be given temporary order IDs you can continuously poll. Not very effective.
This is probably why the industry as a whole hasn't moved off FIX.
It’s better, but it’s not guaranteed to be lossless like FIX. So recovering automatically after bounce/outage/gap is a bit tricky and still REST based.How about WebSocket?
