tala
A zero-dependency TypeScript library of stock indicators with a fluent chain API.
tala is a technical analysis library written in TypeScript. You give it an asset’s price history and chain the indicators you want, such as moving averages, RSI and MACD. It gives the data back with those indicators added. It has no runtime dependencies for normal use. A chart() method draws the indicators against the price, so you can see what they are telling you instead of reading raw numbers.
