Initial Balance (IB) Extension Indicator

Hey all,

I’ve been working on a custom indicator that draws IB extension levels automatically after the IB seals at 9:30 AM CT. Specifically I’m trying to plot horizontal lines at IB High, IB Low, IB Mid, the 0.2 extension above and below (TP levels), and the 0.1 level above and below (SL levels). Lines should persist until the next session resets at 8:30 AM CT.

I’ve been using AI to help me write the JavaScript but I keep running into issues; either syntax errors, the indicator not appearing in the list or it showing up but not drawing anything on the chart.

Has anyone built something similar or can point me in the right direction? Appreciate any guidance.
