Pound vs Dollar - 30 minute chart - Action and reaction linesGBP/USDOANDA:GBPUSDPrinciplesofmathprobAfter all that decline, the market had trouble making new lows. It reached up to a previous range (blue lines) and started making swings to the upside. This area is a buy zone for me. There are 2 rectangles on the chart. The small one is a 15 pip stop, the big one is 25. They are examples of valid stops placed below previous lows. The take profit is a minimum of 3:1.
