Release Notes
I’ve made a couple of upgrades to my London Session range indicator to make it more flexible and customisable:Line Extension Control
- Instead of hardcoding the session range lines to extend 30 bars forward, I’ve added a setting where I can choose how many bars the lines extend. The default is still 30 (which works well for the 15-minute chart), but I can adjust it to suit different timeframes or personal preference.
Editable Capture Window
- Originally, the script was locked to just the first 15 minutes of the London session. I’ve now made that adjustable too. I added a setting that lets me choose how many minutes I want to track the range for — whether it's 15, 20, 30 minutes, or even longer. This is great for tweaking the indicator based on how volatile the open is on any given day.
These changes make it more useful for testing, adapting to market conditions, or just tailoring the session range to fit my own trading style.
Release Notes
No need to chnage the line extension bars they are now dynamic based on the capture time frame - they will always now extend to the end of the London session.Release Notes
