Crossing55 by Kloov

The strategy of using crossing emas was popularized by a youtuber.

This simple script uses the 8, 13, 21, and 55 EMAs.
When the 8, 13, and 21 cross OVER the 55 ema -- long.
When the 8, 13, and 21 cross UNDER the 55 ema -- short.

Alerts available for printing long and short indicators.

100 and 200 emas are added for simplicity but can be turned off in the options.
