It is common in trend-following and exit management systems.\n\n## Formula\n\nPSAR iteratively projects a stop-and-reversal level using the current trend direction, acceleration factor, and extreme price.\n\n## Parameters\n\n- `period` - default `2`\n- `af` - default `0.02`\n- `afmax` - default `0.2`\n\n## C++23 API\n\n```cpp\n#include \u003Cnonabt\u002Findicators\u002Fpsar.hpp>\nauto psar = std::make_unique\u003Cnonabt::PSAR>(data(), 2, 0.02, 0.2);\n```\n\n## Common Usage\n\n- Use PSAR as a trailing stop.\n- Use a price cross through PSAR as a trend reversal trigger.\n- Works best when the market is already trending.\n\n## Practical Pattern\n\nBuy while price stays above PSAR and exit or reverse when price falls below it.\n"]
