Quote from slacker:
Given the same internet connection, only trading 4 instruments, how much better is ZenFire over InteractiveBrokers? Is the difference between ZenFire and IB noticable if trading only a few markets? Or, is the difference only hype?
My personal experience with trading both of them live is that they are very comparable. The supposed Zen 'advantage' is unbundled ticks, you see the actual individual prints a little better. It SEEMS faster. IB groups them up slightly so you see bigger block prints. It SEEMS slower.
It is really a matter of preference. Some people like the Zen because it is a little more precise, others like the IB because it is a little easier to follow on the DOM. This was my experience and others have said much the same thing.
Both have had an OCCASIONAL freeze or glitch - which is probably the CME anyway, it is not perfect and transmits its lag through any platform sometimes - especially at news releases.
I can say for sure that IB has overall had more disconnects than Ninja Zen, at least through my broker's setup - I can't speak to other broker's setups. But mine has it down very well. Nearly flawless, which is as good as it gets.
There is another choke point. There may ALSO be an issue with delays between front-end platform and the 'back office" system (trade confirmations) of certain brokers, their servers, etc.
I would go so far as to say there is no data feed or platform that is completely immune to this. If the parent source of the data freezes, so will everything downstream.
Again, you have ISP hubs, routers, servers and other issues that will make freezes/lags also.
