Fibonacci Retracement Conditions

Fibonacci retracement conditions are used to detect price reactions at key Fibonacci levels during uptrends or downtrends. These are commonly used in technical analysis to identify potential reversal or continuation zones.

All Fibonacci retracement conditions inherit from the base Condition class and implement the standard evaluate, get_graphs, and to_dict methods.

UptrendFibRetracementLevelCondition

Returns True if the price pulls back to a specified Fibonacci level during an uptrend.

Arguments

UptrendFibRetracementLevelCondition(fib_level: FibonacciLevels, length: int)
  • fib_level: The Fibonacci level to test. Supported levels are linked here.
  • length: Lookback period for detecting the local swing high and low.

DowntrendFibRetracementLevelCondition

Returns True if the price bounces back to a specified Fibonacci level during a downtrend.

Arguments

DowntrendFibRetracementLevelCondition(fib_level: FibonacciLevels, length: int)
  • fib_level: The Fibonacci level to test. Supported levels are linked here.
  • length: Lookback period for detecting the local swing high and low.

Examples

condition = UptrendFibRetracementLevelCondition(
    fib_level=FibonacciLevels.LEVEL_50,
    length=20
)

This condition is met if the price retraces to the 50% Fibonacci level during an uptrend over the past 20 days.

condition = DowntrendFibRetracementLevelCondition(
    fib_level=FibonacciLevels.LEVEL_61_8,
    length=30
)

This condition is met if the price retraces to the 61.8% Fibonacci level during a downtrend over the last 30 days.
