That’s very difficult to find a professional broker nowadays;because there are almost thousands online broker in retail market place and most of them are found to be scams.
Practically the professional broker does not cheating at all to theirclients and don’t restrict any kinds of trading techniques. In my trading career I am very lucky tochoose TempleFX which is real STP Execution trading platform and does not restrict any trading techniques with scalping and hedging. And they don’t have any kinds of hidden fees. So, I get all profit that I earn.
