openalgo-chart-indicator

Add or author an indicator. Read indicators for the full built-in catalogue with exact ids, inputs and defaults before writing code - do not guess an id. There are 91 built-ins and the ids are hyphenated lowercase, not derivable from the display name (williams-percent-r, not willr).

Arguments

• $0 = indicator id, or a plain-language name to resolve to an id.
• $1 = target pane. Default: whatever the descriptor's placement says.

Step 0 - the tier must be imported

import 'openalgo-charts/indicators';   // side effect: registers the 91 built-ins

Without it chart.addIndicator throws. Add this import once, at the app entry, not in every module. Verify it is present before adding an indicator:

rg -n "openalgo-charts/indicators" src app
