Please see the chart on the left. Note the points marked 2 and 3.
When a grey candle low touches the Macro Wave, a Green marker is placed. This grey candle is the first candle to touch the Macro Wave after Macro Wave red line crosses over the blue line. A buy trade above this red candle high with the stop loss placed on the Macro Wave blue line may be considered for a low risk long entry.
A "U" turn of the Fast Wave inside the Macro Wave is also a good entry point for a long trade with the stop loss placed on the Macro Wave blue line for a low risk trade opportunity.
Observe the Yellow Zone of the Fast Wave in the chart. When the Fast Wave red line curves down but does not cross below the blue line, it is a sign that price might resume the upward move again. This is a pattern worth looking at for possible long entry as well.
