Hey thanks everyone for the input .
I am currently testing Deltastock's L2 module however I have a query (for your Deltastock representative who posted previously ):
When I am at the L2 module I find that I can choose from the various counterparties as detailed here on your website:
http://www.deltastock.com/english/platforms/level2.asp. What I cannot figure out though is why orders are only revealed when I've chosen'Delta' as the counterparty (or'SMART')??? In other words: should I choose IB (that from what I gather is really Interactive Brokers)...
