CQG or ZenFire...whats the difference? Anyone have any suggestions?
- it is still in Beta
- they seem to have stopped development on it.
- you have to get your broker to advise ZF that you are allowed to login twice with the same password ie once on NT and once via the Web Trader.
- the Web Trader has an option for access via the iPhone. There is no app - just save the web address to the iPhone. It is cluncky to login on the iPhone, but once in the formatting is not bad for the phone.
- on Web Trader (on a PC) you can have multiple DOMs going, you can have a quote board and monitor live and completed orders plus your account balance. Putting instruments on the quote board is a pain - you have to know the full exchange code/path for each and change at each contract rollover.
Can you help answer these questions from other members on NexusFi?
I thought that both feeds supply 10 levels (not 100% sure, though), but NT only shows five.
If so, this can't be the reason for the difference. Maybe the difference has to do with how exactly the data is structured. E.g. when price ticks 1 up, taking the offer 1 up with it and thus revealing the number at offer+10 levels, simultaneously someone submits an order 5@offer+3, how many data ticks would that be in the two feeds?
The difference in the QuoteManager with ZenFire versus CQG is only for best bid, best ask and last trade. So for that comparison it doesn't matter how many levels the data feed provides, since only the first levels are saved for each data feed. (Of course, for actual trading it might matter )
They don't look completely different (see below), but they're perhaps different enough to give different results (depending on the strategy type used).
For example, the opening bar from CQG is very different from ZenFire. Besides that, there are some smaller differences (see for example the bar high's and close).
I'm not sure what I should make of this. CQG provides more updates, but if I look at the wide range opening bar from CQG I'm more inclined to think ZenFire has a better feed. But that's still quite subjective and circumstantial.
EDIT:
You've raised a good point vvhg, in real-time trading the charts may be quite different. For example, the following example taken from real-time might give two traders, both looking at the same instrument on the same platform with the same chart settings, a slightly different bias about the price:
Also note that the volume for both charts is different, with the ZenFire chart displaying the same volume as IB TWS, while the CQG has a lower volume. For the people not familiar with this instrument, the exchange opened about 1 hour 45 minutes ago and the total session lasts 14 hours. I find it troubling that there's already a difference in the volume when we're just in the beginning of the session.
