To check if your forex broker is EA friendly read this carefully.
– is it an STP or dealing desk broker?
– is scalping allowed
– how are the executions
– did you check the data feed (tick data)
– how much is the up time percentage of the mt4 terminal
The questions above you should always check. EA friendly brokers should be in the category where there is no dealing desk and where they allow scalping. Executions are fast and they have no issue with providing tick data. And of course, they should offer a stable platform.
