MRVL stock | 1 m | 5 m | 30 m charts

 How to tell if it is time to buy dip and catch rebound? 

1. One way is to check 30 min chart to make sure that 30 min bar is not a trend bar - candlestick pattern - STW pattern etc
2. Easy way is to compare EMA 8, and if the bar stays below EMA8 all the time, and just wait. 
3. 5 min chart - bar count 42 - Stay below EMA 8 all the time until bar count 42 - trend bar - green 
4. That is the time to get in - Bar count 42 or 43, and I think that bar count 43 is better to confirm the uptrend and rebound
