I'd like to visualise time-based opening range directly on my DOM chart

Please take a look at my current DOM configuration, I highlighted in pink hypothetical opening range with low of 13777.25 and high of 13784.25 and I'd like to have it visualised by either some vertical lines above range high and below range low or by different background color for all rows in range.

I've seen some guys posting their sierra DOM's with additional lines drawn, but I'm not sure how to replicate this.

Any ideas?

On a chart apply one instance of Initial Balance study.
On the study settings page:
Set it to Daily
Set your Start time
Set your End time less on second than the time you actually want as an end time. Trust me on this or read the manual as to why this is so.
Set Use Start/End Time as your method

On Subgraphs, set SG7 to the line type/size you want plus Name and Value for IB Hi
On Subgraphs, set SG9 to the line type/size you want plus Name and Value for IB Lo
Set all other Subgraphs to Ignore or Hidden.

Apply the Study to the chart. You should have the IB lines and values appear on the your chart.

On the DOM, under Chart menu select Studies
Select Study/Price overlay and apply it.
Under settings for the Study/Price overlay select the source Chart number and the Study ID number for the IB Study on the source chart you just built.
Hit Apply and OK.

You will have the IB lines and info from the source chart on the DOM.
