What's your current latency to the Chicago area? Perhaps you could improve it with a different internet provider? Just a thought.
I was referring to your office or home internet provider. While you may use generictrade you still have to connect to their servers from your location. Can you improve the latency between your workstation and generictrade?
The slippage depends on the strategy you use. 99% of the algos out there will still have the same results regardless if you have a VPS or not....the main question is what type of slippage you experiencing and if it is really a slippage or just the mechanics of the market/first come, first serve...what specific market?
Slippage could depend on your size, frequency, instrument, and your proximity to that data center. If you'd like a test server, send us a message via our live chat on our website.
Personally I dont think a VPS will help but might be worth exploring, especially a free trial. If you can share some examples of slippage with what the order was doing, time placed, fill time and fill price I can shade more light.
