Help me to choose which account type to open?

A broker offered me these account type and I am not clear how they are different and which one to choose, any help would be appreciated:

  • How different between floating spread and fixed spread?
  • Market execution and instant execution
  • swap free
  • EA trading allowed
  • 4digit vs 5 digit

This is not good. I think there are brokers that allow you to trade both the 4 digit and 5 digits with one account type. With my Profiforex Micro account, I can use the 4 and 5 digit quote. All type of quotes are available on their mt4 platform whether it is a Standard or Micro account. This means both account type enjoy the same benefits and the only difference is trading in Micro and Standard lots. And with a Micro account, you can start trading with Cents or at least one $1.

I am wondering if you use both account types, if yes what benefit do you derive from the Micro account?
