    ta4j

    ta4j

    A Java library for technical analysis

    Ta4j is an open-source Java library for technical analysis. It provides the basic components for the creation, evaluation, and execution of trading strategies. Ta4j is available on Maven Central. You can also download example code from the maven central repository. The wiki is the best place to start learning about ta4j. For more detailed questions, please use the issues tracker. We can calculate indicators over this bar series, in order to forecast the direction of prices through the study of past market data. Then we have to build our trading strategy. It is made of two trading rules, one for entry, the other for exit. Ta4j comes with a set of basic trading rules/strategies which can be combined using boolean operators. Trading strategies can be easily compared according to a set of analysis criteria. Ta4j can also be used for live trading with more complicated strategies.

    Rust-Lightning

    Rust-Lightning

    Bitcoin Lightning library written in Rust

    Rust-Lightning is a Bitcoin Lightning library written in Rust. The main crate, lightning, does not handle networking, persistence, or any other I/O. Thus, it is runtime-agnostic, but users must implement basic networking logic, chain interactions, and disk storage. The project implements all of the BOLT specifications in the 1.0 spec. The implementation has pretty good test coverage that is expected to continue to improve. It is also anticipated that as developers begin using the API, the lessons from that will result in changes to the API, so any developer using this API at this stage should be prepared to embrace that. LDK/Rust-Lightning is a generic library which allows you to build a lightning node without needing to worry about getting all of the lightning state machine, routing, and on-chain punishment code (and other chain interactions) exactly correct. Note that Rust-Lightning isn't, in itself, a node.

    Bcoin

    Bcoin

    Javascript bitcoin library for node.js and browsers

    Bcoin is an advanced fullnode implementation built with JavaScript/C/C++/Node.js. It is easier to use, faster to learn, and more well-documented than competing implementations. Engineered from the ground up to create scalable, flexible, and efficient production-ready systems with unparalleled code readability. Bcoin is consensus-conforming and adheres to the strict security standards of the original implementation maintained by Bitcoin Core. Bcoin can be integrated into almost any desktop or browser application to enable native payments, on both Bitcoin and Bitcoin Cash networks. Bcoin is the first full node implementation built specifically for production systems at scale. Originally created to be used as backend infrastructure for Purse.io, Bcoin enables companies to spin up consumer-grade bitcoin applications/wallet systems without the long-term concern of scalability, and security.
