This is a combined indicator of: ICT Killzones + Pivots [TFO] by tradeforopp Marks FVGs by MarkTools
and my own custom indicator that automatically marks out the 50% of the daily range from the high and low at the 6pmEST open to current time. Dynamically updating as the day progresses.
This line is a solid yellow line with no way to customize it because I am too lazy to adjust the code.
