Can I use DOM information from Interactive Brokers? Does it make sense? I assume that it makes sense to apply some volume based algorithms only then when you know this order book, that you can get info about is really market book. If it represents the main part of the market, otherwise this information is negligible in front of all big names doing trading and in light of their orders which you are not aware of.

What information gives me volume info from IB? Can I make assumption about FX order flow based on their data feed?

We can see here that IB covers all important exchanges, but what is their volume? The sum of the all noticed volumes on exchanges? Please could you clarify this issue a little as it was always confusing to me.

Assuming your question is about using the FX 'volume' you see in a broker's DOM or T&S window, you probably can't infer much about order flow in the way you can with other instrument types. FX volume and tick data are not equivalent to what you will see for other instruments. That is, unless the feed is coming from a FX ECN like HotSpot or Currenex, the volume and ticks you're seeing are just quotes, not completed trades.

  • $\begingroup$ how can I see completed trades not at the BID or ASK? ofcourse these are not completed but only limit orders put there. trade may be done only at BID, ASK, but we still can see depth of the market - so these are quoted, right? question is if I can treat these data from IB as from "all the market", after my edit I think maybe yes (?) $\endgroup$

  • $\begingroup$ @cf16 - I'm not positive, but part(s) of Freddy's answer in this question (How is historical data for forex collected or computed?) might shed some light. $\endgroup$ May 4, 2013 at 21:25
