Ultimately its about trying to automate as much as possible to quickly have an awareness of what might be happening on the timeframe above without having to manual enter levels.
I concluded I don't like the results of this script - whilst i clearly see price interacting with on the current timeframe and higher timeframes there is too much screen clutter on the screen for me.
Rather than delete the script I thought I'd make it available for other people to use. I hope its useful to people. Good luck
(For the record it actually takes a little thinking outside the box to make so many display - you can't just plot hlines. If your a pinescript geek you might like the code)
