Additional instructions:
- IMPORTANT: You MUST fill gaps. Without this, the strategy lines will look like a staircase (visual glitch) because the strategy calculates on the weekly timeframe. Use gaps=barmerge.gaps_off or fillgaps=true in request.security() calls.
- The indicator uses request.security() to fetch weekly data. Preserve this timeframe logic in the strategy version.
- Set plot offsets to 0 to preserve visual alignment.
Overview
Bull Market Support Band requests weekly values of the close-based averages so the band stays aligned with the weekly timeframe even on lower charts. The two inputs change the SMA and EMA lengths, which default to 20 and 21. It does not generate buy or sell signals, entries, exits, or risk rules.
- Weekly 20-period SMA
- Weekly 21-period EMA
- Shaded band between averages
- Adjustable SMA and EMA lengths
- Price-chart overlay
