Multi time frame EMA
This script will plot the configured EMAS on the current time frame (CTF) and also the same EMAS on a higher time frame (HTF).
Hard coded according:
* 5m EMAS will be plotted on TF bellow 5m
* Daily EMA will be plotted on TF above 5m and bellow 1D
* Weekly EMA will be plotted on daily TF
* Monthly EMA will be plotted on weekly TF
This configuration give us the opportunity to watch EMA support/resistance from HTF on the CTF
