The AlgoCorner DonchianPSAR indicator visualizes market price asymmetry by combining the Donchian Channel and Parabolic SAR techniques. It adapts automatically to price direction: during rising markets, it plots the bottom of the Donchian Channel to reflect steady upward movement; during falling markets, it switches to the Parabolic SAR to capture rapid declines. This dual approach highlights the typical market behavior where prices often climb gradually but drop sharply. For assets with inverse price dynamics, such as the VIX, the indicator offers a reversible mode to adjust its logic accordingly. Users can fully customize the parameters of both the Donchian Channel and Parabolic SAR components. The indicator supports various markets including Forex, indices, Bitcoin (BTCUSD), gold (XAUUSD), and NASDAQ (NAS100). It provides an intuitive visualization of market rhythm, helping traders understand not only price levels but also the nature of price movements.
