Are you algo trading? Have you written a custom trading bot? Did you buy into an MT4 or MT5 expert advisor? Or maybe you just want to collect data without running your home PC 24 hours a day? If so, a VPS might just be for you! Main considerations: Latency - This is a measurement of time, specifically the time it takes requests from your VPS to be received by your desired broker or exchange. Often overlooked is the latency measured between your data source and your VPS, which may add to overall delay in executing your strategy. For example, you might be lightening fast executing trades, but if price data is delayed by a tenth of a second that will slow down your algos ability to made decisions in live markets. It’s a good idea to start with a month long contract with more than one VPS providers (or use a free trial) and test out latency should your strategy be sensitive to execution delays. RAM - Your custom code might run right, or it might gobble up RAM like cookie monster at a bake sale… Picking a cheaper VPS package that starves your code of RAM will cause the VPS to temporarily store data that should be in RAM to the storage drive which will slow down performance across the board. If you are using off-the-shelf software, make sure to check your software vendor’s RAM requirements and choose an adequate VPS setup accordingly. Any modern install of Windows Server should have 2-4Gbs of RAM minimum. A command line app running on Linux might only need 512Mb of RAM. A good rule for mission critical software is to err on the side of caution and get a little more than you think you need just to be safe.
