Hikyuu is a high-performance open source quantitative trading research framework based on C++/Python, for quick strategy analysis and backtesting. Compared with other quantitative platforms or backtesting software, it has:

1. Ultra-fast backtesting speed (million-level K-line completes A-share market calculation in 1-2 seconds);
2. Abstract the complete system trading concept and decompose it into different components. By reusing different aspect strategies, the burden of writing strategies can be minimized.
