The FZ indicator for cTrader visualizes Fibonacci channel zones based on the highest and lowest prices over a user-defined number of bars (default 21). It calculates channel borders and key Fibonacci levels (0.236, 0.382, 0.618, 0.786) to identify trend zones and potential reversal areas. The indicator overlays these zones directly on the price chart, using color coding to distinguish market conditions: cyan for uptrend zones, gray for ranging zones, and orange for downtrend zones. This helps traders interpret market trends and make informed decisions about entering or exiting positions. The indicator supports various markets including Forex, indices, commodities, stocks, and cryptocurrencies. It is designed to be compiled and attached to any chart within the cTrader platform, with adjustable parameters for the calculation period.
