Trend Conditions

Trend conditions evaluate whether a price or indicator series is in a sustained uptrend or downtrend over a specified number of days. These conditions are useful for capturing momentum and trend-following strategy logic.

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

UptrendForXDaysCondition

Returns True if the specified trading series is in an uptrend for a consecutive number of days.

Arguments

UptrendForXDaysCondition(series: TradingSeries, number_of_days: int)
  • series: A trading series (indicator or price) to evaluate.
  • number_of_days: Number of consecutive days where the condition must hold for the trend to be confirmed.

DowntrendForXDaysCondition

Returns True if the specified trading series is in a downtrend for a consecutive number of days.

Arguments

DowntrendForXDaysCondition(series: TradingSeries, number_of_days: int)
  • series: A trading series (indicator or price) to evaluate.
  • number_of_days: Number of consecutive days where the condition must hold for the trend to be confirmed.

Examples

condition = UptrendForXDaysCondition(
    series=EMA("AAPL", SourceType.CLOSE, 20, 0),
    number_of_days=5
)

This example triggers if the 20-day EMA of AAPL has been increasing for the past 5 days.

condition = DowntrendForXDaysCondition(
    series=CLOSE("AAPL"),
    number_of_days=3
)

This example triggers if the closing price of AAPL has been falling for 3 consecutive days.
