- My professional advice for choosing the right library
By the end of this guide, you‘ll have the insights to pick the perfect library for your app and team. Let‘s dive in!
Why Use a Charting Library?
Here are the main reasons to use a charting library instead of coding finance charts yourself:
Save Significant Development Time
Specialized finance charting libraries provide tons of built-in functionality like:
- Candlestick, line, bar, and other chart types
- Technical indicators – MACD, Bollinger Bands, RSI
- Date-based axes for time series data
- Draggable trendlines and shape tools
You get these features out-of-the-box, avoiding the complexity of developing them from scratch.
Faster Time-to-Market
With a robust charting library, you can build and launch your finance app faster. The library handles the complex charting capabilities so you can focus on your app‘s unique value.
Improved Visualizations
Advanced libraries use GPU acceleration and WebGL rendering to deliver smooth, highly responsive chart interactions. You can offer users an immersive native app-like experience.
Easier Adoption and Use
Leading charting libraries come with thorough documentation, tutorials, and developer support. This enables your team to integrate charts and start development quicker.
Regular Feature Updates
Established libraries like TradingView and AnyChart continuously add new features and improvements. Your app can leverage these latest capabilities without additional coding.
Overall, integrating a dedicated finance charting library significantly accelerates development. Even large enterprises like SoFi, E*Trade, Robinhood, and Coinbase use libraries to power their charting.
Now let‘s explore how to pick the right library for your needs.
How to Choose the Best Financial Charting Library
With dozens of JavaScript charting libraries out there, how do you determine the right one?
Here are the most important criteria to evaluate:
Chart Types
The library should support the essential chart types including:
- Candlestick – The most common chart for technical analysis with open, high, low and close data.
- Line – Typically shows closing price over time. Good for long term trends.
- OHLC – Shows open, high, low and close as separate points.
- Heikin Ashi – Smoothed candlesticks to filter noise.
- Bar – Vertical bars indicate trading range for timeframe.
- Area – Shaded area visualization for quantitative comparisons.
- Scatter – Plots price changes against volume or other factors.
Advanced libraries will also offer more exotic types like Renko, Kagi, Point & Figure charts. But the above are a must-have for most finance apps.
Technical Indicators
Indicators help traders identify trends, momentum shifts, volatility, support/resistance levels and more. I recommend libraries with essential indicators like:
- Moving Averages – SMA, EMA, VWAP, etc.
- MACD
- Bollinger Bands
- Relative Strength Index (RSI)
- Average True Range (ATR)
Bonus points if the library supports adding custom indicators.
Responsiveness & Interactivity
The charts should work flawlessly across desktop, tablets and mobile. Responsiveness ensures the right layout and sizing on all screen sizes.
For interactivity, look for features like zooming, panning, crosshairs, tooltips and annotations. These create engaging experiences for users.
Speed & Performance
Finance apps need to render charts with streaming real-time data quickly – even thousands of data points per second.
Prioritize libraries that offer GPU acceleration and WebGL rendering. These leverage the graphics card for smoother visualizations.
Framework Support
Your library should integrate easily with JavaScript frameworks like React, Angular and Vue.js. This enables syncing chart data and behaviors with the rest of your app code.
Learning Resources
Look for extensive documentation, API references, tutorials and developer support. This helps your team get up and running faster.
