I reckon that trading using VPS is the most valuable tip for you how to make most out of algo trading.
You know... you can have your computer run 24/7, with seamless execution speed and the main is to find proper expert advisors, cause... not all of them are that quality, you know.
It's better to spend more time on finding a good advisor rather than sorting out with vps, afaik it's easily set up here and connection happens within seconds.
Just make sure you meet all the requirements or be ready to pay some $$$ for acquiring access to it.

Hm... I have no particular tips, I can just say that you need to define platform first.
You know, you can algo trade using either MetaTrader or cTrader, since bots are available on both engines. Also, you can pay attention to the virtual private server offered by the broker. It ensures trading 24/7 without necessity to have your laptop/pc run all the time + execution is a bit faster.
