Logical Conditions

Logical conditions are used to combine multiple other conditions using boolean logic. They allow you to construct complex condition trees that can be evaluated as part of a trading strategy.

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

AND

Combines two or more conditions and returns True only if all of them are satisfied at the same time.

Arguments

AND(*conditions: Condition)
  • conditions: A variable number of Condition instances to be combined with logical AND.

OR

Combines two or more conditions and returns True if any of them are satisfied.

Arguments

OR(*conditions: Condition)
  • conditions: A variable number of Condition instances to be combined with logical OR.

Example

condition = AND(
    CrossOverCondition(
        first_series=SMA("AAPL", SourceType.CLOSE, 50),
        second_series=SMA("AAPL", SourceType.CLOSE, 200)
    ),
    GreaterThanCondition(
        first_series=RSI("AAPL", SourceType.CLOSE, 14),
        second_series=CONST(30)
    )
)

This example evaluates if the 50-SMA has crossed above the 200-SMA and the RSI is above 30.
