I ask the broker directly in a phone call whether they allow scalping.
In surprise I found that quite a few people do not know what you mean. You have to explain this term to them and explain what you are trying to do.
I have asked this question of CMC markets, GFT forex and Hallifax and Kinetic Securities in Australia. They all say basically the same thing - if the price is on the chart and you click it, then it is a legitimate trade.
They say it does not matter if you only make one pip - as long as they make their spread - which they will if you are clicking on their prices !
But how many times, and at what leverage? Again there is no problem - as many times as you like - just click on the prices on the chart is their reply.
Everyone who knows me on this forum knows that I specialise in scalping.
I think that these are fair answers and I have not had a problem in this area with my broker. Too many rumours float around, I think.
