I've always been at exchange minimum with them. Their commissions are probably not the lowest, though. For my trading, less important than stability of platform.
AMP Futures is now doing their own clearing. Isn't there increased risk on our part with going with such a small clearing firm? And if Zen-Fire uses Rithmic's servers then why is Zen-Fire having all these data feed issues and Rithmic isn't?
Geez. I was sloppy in my description. I *meant* to say ZenFire licenses Rithmic's server application... not their application/server. They run on different hardware, hosted at different data centers. And so far (knock on wood), Rithmic seems to be doing a better job of engineering. I would venture to guess this is probably because ZenFire is run by former traders, while Rithmic is run by engineers.
I did side x side with Pats and XTrader applications against ZenFire feed through Dorman, which hosts those servers, and they were neck and neck, so, so much for zen-freeze rofl
i did the same test. you will see the freeze when the market moves fast. try it today on FED (it could be also a Ninja problem...)
