Display Horizontal Trendlines For Set Times

Hi! Thank you for your time. I'd like someone to code some horizontal indicator trendlines on MT5 please.

The lines are to identify key times on the chart at current or last price at 1 hour and below time frames for all charts.

Please refer to the attach picture as an example of what I'm after.

As you'll see in the example there are small labelled boxes for "Futures", "Forex" and "Price Levels". These represent show/hide toggle boxes for each corresponding horizontal trendline that can be toggled on or off. See below for the corresponding line labels. 

So for example; I'd like a horizontal trendline that paints at 8am GMT time with the label "London Open" for the current day only.  

I'd like the toggle buttons to be placed on the bottom left of the actual MT5 chart but not as large as the example, maybe 2px smaller.

Thank you!
