Yes, Cboe Silexx will work with your firm on a custom, automated importing solution for your firm's start-of-day position & buying power files. We are able to seamlessly reload files intraday, immediately reflecting any changes in the trader's terminal.

Cboe Silexx uses a highly efficient proprietary compression and transmission protocol, and we do not employ any symbol subscription limitations. On a regular 3Mbit/sec DSL line, you can easily subscribe to several thousand symbols, and we have clients with large portfolios that are subscribing to more than 50,000 active tickers. As a rule of thumb, depending on the activity of the symbols you are watching, Cboe Silexx consumes ~15Kbit/sec per 500 symbols.

All those millisecond and microsecond numbers you see being thrown around in the press ignore multiple factors of latency and often are a result of incorrect/inadequate measurements. For a manual trader, the single biggest source of latency are your fingers, and if you can click more than 5 times per second, that's really good. If you put this in numbers, the average person has a 200ms to 300ms delay from thinking to clicking the mouse, to actually executing the click. The second biggest source of latency is introduced by your physical connectivity to our order gateways. Depending on your location, sending an order from San Francisco to New York, takes around 30-40ms. Now, for bragging rights, after our order gateway receives your order, we run all necessary risk checks, validate the order and send it out to the exchange. Our mean-time latency is ~150µs (microseconds), which is ~3,000 times faster than the time it takes for the order to travel to us. Bottom line, yes, our systems are insanely fast and deliver your orders to the exchanges with negligible overhead.
