Scanner for Multipe EMA Crossover 5/20/50

Hello usethinkscript community!

I would like to get help with coding for creating a script that combines the 5/20 ema crossing above and below the 50 ema to scan for potential breakouts during premarket and during the regular trading session. I am specifically looking for all three moving averages to cross at the same point in time or at least within 15 minutes. I like the 5 and 15 minute timeframes to spot early entries into big movers. Thanks again.

Go Big and Godspeed

i don't scan , so i don't make scans.
here is a lower that should work.

this looks for 2 crossings,
..ema5 crossing above ema20
..and ema5 crossing above ema50.

if the 2 crossings happen within x minutes, then the output is true.
can pick the max minutes...

set the chart/scan time to be less than the max minutes.

I love your upper study but I haven't been able to modify it for SELL signals. How could I?

First time I try any coding (if you can call it so) but here is the modification of the original from @halcyonguy, I added warn and sell signals for shorting and the option to show warn-sell or not. I hope I'm posting this correctly:
