By drawing this price trap box what you see on the chart, the grey area shows where you will be making profit from the market. For a BUY STOP you will enter your trade at the top of the RED box and take your profit at the top of the GREY box. The same technique applies for a SELL STOP.
You will be able to notice that price always moves through the GREY box each time which is basically creating you LOW RISK trades and MAXIMIZING PROFITS.
Always be aware of your RISK MANAGEMENT.
