The proper charting techniques and indicators are necessary to define the trading style. A strategy can be the same for everyone because if you are doing price action trading or day trading some other person is also using the same technique. The difference between the two is that (or the matter of fact in everyone) the indicators, the charts or the timings of the trade will be different. The broker then comes into play when all of these things are sorted. For example I need low spreads, high leverages and mobile trading, so I choose multiple brokers i.e. Fxview and XM because it gives me the features which I want according to my ‘trading style’.
