8,21,40 EMA by gmubird
Best used with 1 min time frame. On a solid trend usually the candles with stay above the 8 ema while retesting it every 5-15 bars. If it breaks the 8 ema then look for it to test the 21 ema . The 21 is useful on the 5 min as well because a trending stock with sometimes test the 21 for support and bounce off. However if it breaks the 5min 21 ema it's probably going to break it's short term trend and maybe go side ways or reverse. The 40 ema is mainly useful in the 1min because it helps visualize the 5min 8 ema . This is the main tell for a solidly trending stock/ spy because they love to test this over and over through a trend. Just watch for a break of it because it means a kinda good chance of the end of a trend and a good time to sell.
