Increasing test (ta.increasing)

View Markdown

Test whether input increases over the specified period, optionally requiring consecutive increases.

Run this example

This complete script uses bundled data. It observes the selected output without placing trades.

import numpy as np
from openbacktesting import Backtest, Strategy
from openbacktesting.test import GOOG

data = GOOG.copy()

class Example(Strategy):
    def init(self):
        self.value = self.ta.increasing(self.close)
        self.latest_value = None

    def next(self):
        channel = self.value
        if channel.valid[-1]:
            self.latest_value = float(channel[-1])

result = Backtest(data, Example).run()
print(result["_strategy"].latest_value)

Call and parameters

self.ta.increasing(
    source=None,
    *,
    length=1,
    strict=False,
    asint=True,
    percent=False,
    drift=1,
    inputs=None,
    backend=None,
    required_outputs=None,
)

Register in init(). Read the returned channel in next() after checking valid[-1].

Parameter	Meaning	Type	Default	Allowed values
length	Calculation window in observations.	int	1	Minimum: 1
strict	Require every adjacent comparison in the window to satisfy the direction.	bool	False	No additional constraints
asint	Return numeric 0/1 flags instead of booleans.	bool	True	No additional constraints
percent	Percentage threshold for directional changes.	bool	False	No additional constraints
drift	Bar lag for differences.	int	1	Minimum: 1

source/named source arguments accept a column name or same-run single-channel handle. Alternatively, inputs maps each input below to a column or handle. backend selects a supported implementation; required_outputs selects channels for readiness diagnostics. See shared arguments and handles.

Inputs and outputs

Required inputs: close.

Channel	Meaning
increasing	Increasing test value

Reading values safely

Insufficient history or missing inputs can make a channel invalid. Check that channel's valid mask; ready is diagnostic and never suppresses next(). Multi-output results may have different valid channels on the same bar.
