Does anyone know which platform I can use to get the fastest quotes and order execution? I currently use TradeStation and want to know if there is something faster out there.

CHoose one close to your exchanges, network wise, and you are pretty good to go.
Automated trading from home is - hm - "tricky" 24/7 thanks to - well - the fact that your SLA's all the way to the technical provider suck. I dont like 2 days without internet, having a diesel generator in my home for power outages etc.
