Ideally one lightweight enough to run on a raspberry pi. Should at least be integrated with Alpaca, and support 1-hour intervals.

I've developed NextTrade (GitHub link), the worlds best open-source UI-based trading platform. It has functionality that no other trading platform can match including:

• Creating trading strategies using a simple, easy-to-use UI

Strategy Page

• Backtest those strategies using historical data

Backtest Builder

• Live-trade those strategies in the market

Deployment Settings

• Optimize the parameters of the strategies using advanced AI algorithms (NSGA-II multi-objective optimization)

Optimization Page

Being 100% open-source, users are able to

• download the code

• change whatever they want

• see how the advanced algorithms are implemented

• create new trading conditions

• EASILY connect the app for live-trading

It’s perfect for the novice trader looking to develop their own platform or trading strategy.

Why open-source it?

NextTrade is a great platform to give users inspiration to create their own platform or trading strategy. In practice, the app's backtesting functionality is too slow and memory-intensive for complicated trading strategies. This in particular makes the optimizations take orders of magnitude more time than they should. Moreover, the architecture for the "strategy" concept was implemented in a way that makes it too rigid. It's not configurable enough to implement extremely complicated ideas (think the 5Day SMA * 0.7 > 300 Day EMA + 0.3*SD).

That’s why I started from scratch and am working to implement the next evolution of NextTrade, called NexusTrade. NexusTrade is built off of the idea of NextTrade, but is A LOT faster, more configurable, and more accurate. Some of the features include:

• The ability to create ANY trading strategy you can imagine using a simple, easy-to-use UI

  • Ideas like the 5Day SMA * 0.7 > 300 Day EMA + 0.3*SD are super easy to implement without needing to know how to code at all!

More configurable condition page

• Backtesting the strategy over decades of historical data in seconds

• Optimizations are now A LOT faster

• You can create strategies with an AI-Powered Chat

• (Coming soon) the ability to live-trade in the app

• the ability to optimize the strategy using genetic algorithms

NexusTrade also has a Roadmap so you can see exactly what I’m working on, and offer suggestions for features you would use.

Both platforms are completely free. If you want to learn how to build your own trading platform or implement trading strategies, you'll get more value from NextTrade. If you want to create a trading strategy, but don’t have time to learn to use a complicated platform, you should check out NexusTrade.

I am looking for a open source trading platform that I can customize. My interest is in trading currency both fiat and digital.

I have narrowed my shortlist down to 6 github projects.

I would like to know which of the following projects is the most robust and closest to being production ready. And in the case of the 'standard currency' oriented platforms which is most easily extensible to able to do crypto trading also.

P.S. Programming language is not a big consideration for me. But execution speed might be.

Standard Currency

• Zipline (Quantopian Hedge Fund) - [5,281 Stars] [1,712 Forks] [88 Contributors] [Python] - https://github.com/quantopian/zipline

• LEAN (Quantconnect) - [972 Stars] [634 Forks] [58 Contributors] [.NET] - https://github.com/QuantConnect/Lean

• Backtrader - [753 Stars] [234 Forks] [26 Contributors] - https://github.com/mementum/backtrader

Crypto Currency

• Gekko [2312 Stars] [747 Forks] [77 Contributors] [JS] - https://github.com/askmike/gekko

• StockSharp [987 Stars] [435 Forks] [17 Contributors] [C#] - https://github.com/StockSharp/StockSharp

• Tribeca [830 Stars] [233 Forks] [18 Contributors] [JS] - https://github.com/michaelgrosner/tribeca

If there are some other open source platforms that should be on my radar I would be glad to hear about them.

Cheers.
