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.adxr()
        self.latest_value = None

    def next(self):
        channel = self.value.adxr
        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.adxr(
    *,
    length=14,
    lensig=14,
    scalar=100.0,
    mamode='rma',
    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 14 Minimum: 1
lensig ADX signal smoothing period. int 14 Minimum: 1
scalar Multiplier applied to the formula output. float 100.0 Minimum: 1e-08
mamode Moving-average algorithm; choose one of the listed values. str rma Allowed values: ['sma', 'ema', 'rma', 'wma']
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: high, low, close.

Channel Meaning
adxr Adxr output
positive Positive-direction component
negative Negative-direction component

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.
