npm install financial-toolkitOr with yarn:
yarn add financial-toolkit- Simple Moving Average (SMA): Calculate the SMA over a specified period.
- Exponential Moving Average (EMA): Calculate the EMA for trend analysis.
- Relative Strength Index (RSI): Measure the speed and change of price movements.
| Function Name | Description | Example Usage |
|---|---|---|
sma(data, period) |
Calculates the Simple Moving Average (SMA) over a specified period. | const smaValues = sma(prices, 5); |
ema(data, period) |
Calculates the Exponential Moving Average (EMA) over a specified period. | const emaValues = ema(prices, 5); |
rsi(data, period) |
Calculates the Relative Strength Index (RSI) for a given dataset. | const rsiValues = rsi(prices, 14); |
Here’s a quick example of how to use the Financial Toolkit:
import { sma, ema, rsi } from "financial-toolkit";
const prices = [
22.27, 22.19, 22.08, 22.17, 22.18, 22.13, 22.23, 22.43, 22.24, 22.29,
];
const smaValues = sma(prices, 5);
const emaValues = ema(prices, 5);
const rsiValues = rsi(prices, 14);
console.log("SMA:", smaValues);
console.log("EMA:", emaValues);
console.log("RSI:", rsiValues);Contributions are welcome! If you have any ideas, improvements, or new indicators that you’d like to see, feel free to submit a pull request.
