talib.version // TA-LIB version string
talib.functions // Array of all available functions
talib.functionUnstIds // Function unstable period IDs
talib.execute(params[, callback])Execute a technical analysis function.
Synchronous:
const result = talib.execute({
name: 'SMA',
startIdx: 0,
endIdx: data.length - 1,
inReal: data,
optInTimePeriod: 20
});
Asynchronous:
talib.execute({
name: 'SMA',
startIdx: 0,
endIdx: data.length - 1,
inReal: data,
optInTimePeriod: 20
}, (err, result) => {
if (err) return console.error(err);
console.log(result);
});
With Async/Await:
const result = await new Promise((resolve, reject) => {
talib.execute(params, (err, result) => {
if (err) reject(err);
else resolve(result);
});
});
talib.explain(functionName)Get detailed information about a function's parameters.
const info = talib.explain('ADX');
console.log(info);
// {
// name: 'ADX',
// group: 'Momentum Indicators',
// hint: 'Average Directional Movement Index',
// inputs: [...],
// optInputs: [...],
// outputs: [...]
// }
talib.setUnstablePeriod(functionId, period)Set the unstable period for a function.
talib.setUnstablePeriod(talib.functionUnstIds.TA_FUNC_UNST_EMA, 30);
// Simple Moving Average
const sma = talib.execute({
name: 'SMA',
startIdx: 0,
endIdx: prices.length - 1,
inReal: prices,
optInTimePeriod: 20
});
// Exponential Moving Average
const ema = talib.execute({
name: 'EMA',
startIdx: 0,
endIdx: prices.length - 1,
inReal: prices,
optInTimePeriod: 12
});
// Relative Strength Index
const rsi = talib.execute({
name: 'RSI',
startIdx: 0,
endIdx: prices.length - 1,
inReal: prices,
optInTimePeriod: 14
});
// MACD
const macd = talib.execute({
name: 'MACD',
startIdx: 0,
endIdx: prices.length - 1,
inReal: prices,
optInFastPeriod: 12,
optInSlowPeriod: 26,
optInSignalPeriod: 9
});
// Bollinger Bands
const bbands = talib.execute({
name: 'BBANDS',
startIdx: 0,
endIdx: prices.length - 1,
inReal: prices,
optInTimePeriod: 20,
optInNbDevUp: 2,
optInNbDevDn: 2,
optInMAType: 0 // SMA
});
// Average True Range
const atr = talib.execute({
name: 'ATR',
startIdx: 0,
endIdx: prices.length - 1,
high: highs,
low: lows,
close: closes,
optInTimePeriod: 14
});
When an indicator accepts optInMAType:
const MAType = {
SMA: 0, // Simple Moving Average
EMA: 1, // Exponential Moving Average
WMA: 2, // Weighted Moving Average
DEMA: 3, // Double Exponential Moving Average
TEMA: 4, // Triple Exponential Moving Average
TRIMA: 5, // Triangular Moving Average
KAMA: 6, // Kaufman Adaptive Moving Average
MAMA: 7, // MESA Adaptive Moving Average
T3: 8 // Triple Exponential Moving Average (T3)
};
