Technical Analysis

The calculateIndicator tool lets you compute technical indicators using an Excel-like formula syntax. It works across equities, crypto, and currencies with the same syntax.

Basic Usage

You: What's the 50-day moving average of AAPL?

Alice: [calls calculateIndicator(asset="equity", formula="SMA(CLOSE('AAPL', '1d'), 50)")]
       AAPL 50-day SMA: $189.42

The asset parameter determines which data source to use:

equity — Stocks (e.g. AAPL, MSFT, NVDA)
crypto — Cryptocurrencies (e.g. BTCUSD, ETHUSD)
currency — Forex pairs (e.g. EURUSD, GBPUSD)

Formulas support arithmetic: +, -, *, /

CLOSE('AAPL', '1d')[-1] / SMA(CLOSE('AAPL', '1d'), 200)[-1]

Examples

Moving average crossover check:

SMA(CLOSE('AAPL', '1d'), 50)
SMA(CLOSE('AAPL', '1d'), 200)

RSI overbought/oversold:

RSI(CLOSE('NVDA', '1d'), 14)

Bollinger Bands:

BBANDS(CLOSE('AAPL', '1d'), 20, 2)

MACD:

Daily (`1d`)	~2 years
Weekly (`1w`)	~5 years
