Currently we don not offer any mobile trading platform, but you can access bitfinex.com from any browser, including a mobile browser.
Latency would not have any real meaning in this context, because you are accessing us over the internet. The scale of latency internally is dwarfed by the variation you will experience based on where you are coming from and what route you are taking. All of our information is "real-time", in that there is no delay on any price or trade information. As far as trading engine performance, our current engine has performed remarkably well so far, but as our volume continues to rise, we are upgrading our back end systems, and that process is nearing completion. This should give us the ability to handle millions of orders per second, as well as allowing us to offer many new features.
The maximum allowed margin is 3.3 to 1, or in other words, you must have 30% of the total position size as collateral, and in order to maintain the position, you must have 15% of the position, or your position will be in danger of being liquidated. There is no lot size, necessarily, in BTC. Our minimum order size varies based on account size, and in general is only there to avoid spammy orders.
