For the SFE EAs, enter some seconds before of after don't have to be relevant.
I use this cheap VPS Cloud Ram 1 and I have 6 metatraders in the VPS without problem 24x7 and without restart the VPS never. You can chose a datacenter in canada, that is very near of NY, where a lot of brokers have his datacenters.
