In case this helps others when using EMA's on multiple timeframes, I decided to publish this script I modified.
It adds the EMA for 20/50/100/200 timeframes and gives them the color white, orange, red, green respectively.
The weekly timeframe will get the corresponding weekly EMA.
The monthly timeframe will get the corresponding monthly EMA.
The daily timeframe, and all timeframes below this, will get the daily timeframe. The idea that that a ticker symbol might respect with strength the daily EMA's - you'll be able to move to a smaller timeframe and still view the daily EMA's in an effort to better view how close the ticker came to taking a specific EMA.
