From peer into my NIC [assuming a very fast switch so that its time is negligable], less than 20 microseconds. Most people prefer to measure "end to end": from market data =>NIC , and NIC <= order data. So Peer MD=>NIC=>Trading Algo=>Order=>NIC=>Peer From NIC to NIC. Doing it from Peer to Peer requires nano/micro synchronization of clocks that is not so trivial to do. But this has nothing to do with retail trading. In that scenario, probably 250 Millis is fine. In other words, a THOUSAND times worse than I am willing to tolerate in an arbitrage situation.
I would like to know where does Rithmic, Zen-Fire, and CQG fill in amongst the ones you mentioned. I am only interested in the lowest latency datafeeds possible, but is it even important if the computer from which trades are generated is in New York and not in Chicago? Thanks
Nitro, can you please define what Peer MD, NIC, Trading Algo, Order, NIC, Peer stand for. As I understand it, Nic is the network card in the computer (hardware device) Trading Algo is the software you use to generate orders (NinjaTrader, Tradestation, Etc) Order is the order that is placed by the Trading Algo. Then you have NIC again?? Why? Then peer again ?? How much $$ are you spending a month to get less than 20 microseconds lag? 250 milliseconds is way to much of a lag. I was thinking of 50 microseconds at most, but based on what you are saying it may not be possible to achieve with NinjaTrader as the Trading Algo and Rithmic as the datafeed, correct? Thanks
