Morning Straddle Session Highlight

First draft of this indicator.

This indicator marks the range between midnight and 6am UK time for the morning straddle strategy.

Better used in currency pairs, it will colour code the box based on how big the range is, blue being quite narrow, green the expected neutral range, orange if range is bigger than average and red if there was a big range of movement already overnight.

It will work in other assets, but it may always show a red box.
