Weis & Wyckoff System v2.0 is an open-source trading indicator for the cTrader platform that visualizes market waves and volume based on the concepts of David H. Weis and Richard Wyckoff. It supports multiple chart types including Candles, Heikin-Ashi, Tick, Range, and Renko charts. The system numerically displays wave patterns and volume dynamics to assist in market analysis.

Key features include:
- A versatile Params Panel with four layout templates (Insider, Time, Volume, BigBrain) for quick and user-friendly customization.
- Enhanced ZigZag functionality with multi-timeframe support and multiple modes such as ATR, Percentage, Pips, and NoLag High/Low.
- Integration of order flow aggregation improvements, including custom moving averages, performance drawing, strength filters (MA, StdDev, or both), and high-performance tick volume and wick calculations.
- Dynamic TimeLapse feature showing time waves across various intervals from milliseconds to days.
- Compatibility with Mac OS and requires .NET 6.0 or higher.

The indicator is a C# adaptation and improvement of original PineScript concepts, designed to provide detailed wave and volume visualization without repainting options. It is maintained as open source, with code available on GitHub for transparency and further development.
