I think scalping is the last risky strategy. I judge that it is not goodish understanding not allowing professionals to manipulate with scalping only since computer involving broker couldn't handled assemblage. Perhaps that occurred throughout short broker agents which commonly used worsened server when compared with commonly broker agents. Perhaps scalping will slow down their server because of too many traders coming in at the same time and getting filled and more opened again almost immediately. This is the main reason I think that it will slow down the trading server of the broker.
