I often get questions from traders to check a chart they took a screenshot from. The first thing I do is look up the same currency pair in my own charting platform. Why do you think this is?
As a discretionary trader, I value my chart layout as much as the chart patterns I look for. For many traders, chart-based discretionary trading means finding things like support and resistance, candlestick patterns and trend lines. You discover patterns in how the price behaves. This is the basis of price action theory.
