Simple 5-10-20 EMA crossover look in $BTCUSD

When the 5-day, 10-day, and 20-day EMA are all moving in the same direction, the trend is deemed to be strong (bears still in control)

Trend reversals are confirmed when the moving averages crossover and head in the opposite direction. When the 5-day and 10-day both cross up through the 20-day would be the first red flag to put on a possible long position.
