Function reference

Every Dovee indicator and built-in — signature, parameters, return value, and examples — is maintained in the shared Dovee reference on charting.in. Algocrab uses the same Dovee runtime vocabulary on the chart.

Core indicators (quick list)

• ema(source, length), sma, wma, hma
• rsi(length), macdline, macdsignal, macdhist
• supertrend(atrLen, factor), atr(length)
• bbupper, bblower, basis (Bollinger)
• vwap, adx(length), stoch, cci, williamsr
• keltnerupper, donchianupper, Ichimoku lines (tenkan, …)

Series helpers

• crosses above, crosses below
• change(x), barssince(cond), valuewhen(cond, x)
• mask(series, cond), highest(x, n), lowest(x, n)
• replaceMissing(x, y) / nz

Platform on Algocrab

How scripts compile, backtest, publish to algo trading, and connect to brokers is covered under Getting started and Strategies. Legacy Pine-style AlgoCode may still compile for existing scripts; new work should use Dovee English syntax from the language tour.
