Language reference
AlgoCode includes a large set of built-in functions for indicators and strategies. The table below lists tracked language features and their support level on Algocrab.
Coverage legend
- full — implemented and usable
- partial — limited or demo data
- transpile — syntax transforms to JS bar loop
- planned — on roadmap
- none — not supported yet
AlgoCrab supported surface: 100% full (65/65). TV Spec forever-gaps tracked separately: 6. ta.* aliases 175 → 137 targets / 141 impl.
KPI: npm run audit:pine:kpi — corpus pass-rate. Gaps (cloud libs, tick varip, full Spec AST) are explicit — not claimed as full TradingView parity.
