We recommend you do not use a Browser-based broker, but rather brokers such as MBTrading, Cyber or Castle. They are fully integrated trading platforms with point and click order routing and execution. MBTrading is one of the biggest daytrading brokers offering excellent support and a highly developed trading platform. It's impossible to tell. We see ten traders with an identical mechanical system and their results vary considerably.

The psychological aspect of trading is so critical that we made it our main concern in your education. Knowledge and depth in understanding the processes behind market moves and behavior of market participants is what will make you profitable and successful in trading business. There is no single answer to this question. Daytrading is a process of learning of how to trade more consistently. You must learn how to lose, before you can win.
