Hello,

I have traded for a few years intraday only QQQ and only on ISLD.

Now with recent changes I decide to look on ARCA as an alternative since I need to see depth of the market. What I have found is that on QQQ on ARCA there is almost all the time spread about 4-3cents, while on ISLD spreads very often were even 1 cent and were rarely were more than 3 cents . I know that ISLD is more popular than ARCA, but the steadiness with which the spread on ARCA is maintained looks more like a work of a market maker rather than an ECN at which people shooting orders in front of each other.

Are there any explanations to that?

Thank you.
 
Today spread is better on ARCA - mostly 2-3 cents, sometimes even 1 cent. Probably more players switched from ISLD.
 
personally, i default to redi, the instinet secondarily b/c they have been the most reliable. what have other traders' experiences been?:)

Can you explain what does "write in to the FIX API" means, and elaborate more on this issue if possible.

Thank you.:confused:
