It is assumed that Fibonacci levels help to determine possible levels of correction in the price of a trading pair. Key levels are thought to be 38.2%, 50% and 61.8% as they represent the strongest support/resistance levels. Levels for a corresponding direction in the price movement will appear in the "Uptrend" and "Downtrend" fields.
How to use
In the appropriate fields, type in the lowest and the highest price of a considered price movement and press "Calculate". The calculator will return expected correctional levels for this movement.
