Are you trading/taking Buy or Sell decisions based on 20 day EMA. The below picture will tell you how 20 EMA is inefficient in picking up the trends.
A Buy Signal(Green Arrow) is produced if the candle closes above 20 Day EMA
A Sell Signal(Red Arrow)is produced if the candle closes below 20 Day EMA
When there are too much of crowded mixed signals it is difficult to take the correct signal obviously we will fail to capture the correct trend. More over a sideways trend results in too much distortion in the signal.
If you are a believer of considering 20 day EMA as supports/Resistance for your trades then you need to rethink about modifying your strategy
Now visualize yourself Crossover of the Candle with 20 day EMA cant be the right strategy to trade/invest
