There are many broker that do not allow scalping and hedging. I also faced the same problem with many broker. After a lot of searching Like you I also found Eurotrader broker that allows scalping and hedging. Moreover they have very low spreads as low as 0 pip and flexible leverage starting from 1:50 to 1:500. Their trade execution is also instant without any re-quote. They have over 100 trading instruments including forex, future and CFDs.
Brokers are an important issue in trading. If the broker is not good, the money you have invested will not be safe. Therefore, it is always better to trade in a safe broker. You will feel a lot of joy trading in it. I had a lot of trouble with brokers when I was a new trader. I didn't understand which broker was safe for me. After much searching, I joined the Tpglobalfx broker. That broker helps me a lot with any problem.
