Plots London Open Killzone and New Open Killzone as overlay boxes using current daily high / lows. Boxes verticle location will move as days range / high and low widens.
Middle fills can be turned on and off. Created this indicator because i didnt like highlighting the whole chart background as seen in other ICT Killzone indicators on tradingview and wanted something visually clearer.
If you want additional killzones such as london close / new close, add the indicator to the chart twice.
Boxes height can be changed. Positive number puts the box outside current days high and low, negative number puts box inside current days high and low.
