Hello, and thank you for reading and hopefully answering the following:

looking for a couple weeks for an indicator that will plot a predefined zone after a HTF ema crossover based off the bar of the crossover and then continue to plot those horizontal lines until another cross over (from a HTF data series)

no joy so far in finding one. incase I am looking at the wrong key words or just in
the wrong place: so far looked through zone drawing/plotting, channel drawing/plotting
high/low auto drawing/plotting.

if someone hopefully knows where to find one or atleast some correct keywords would
be certainly appreciated.

Thank you for reading and have a good weekend.

Here are a couple of suggestions.

Visual EMA Multi-Timeframe

Another way is shown in this link on Futures.io
I have not tried this but you can check it out.

HTF Ema

Good Luck in your search.
