The strategy consist in every time that price failed to break any of the EMAs, we need to wait for the right price action and make a buy or sell when it bounce from it to keep surfing on the trend (using the stochastic oscillator and the 5-13 EMAs cross as an additional confirmation).
When do we start looking for a change on the trend? When it repeats the blue tracer (high or low of the previous day) without breaking it and bouncing from it, there will be our signal to start looking for a change of direction on the trend.
