LoggingRetry

API documentation for tradingstrategy.utils.logging_retry.LoggingRetry Python class in Trading Strategy framework.

class LoggingRetry

Bases: Retry

In the case we need to throttle Coingecko or other HTTP API, be verbose about it.

Example how to use:

# Set up dealing with network connectivity flakey
if retry_policy is None:
    # https://stackoverflow.com/a/35504626/315168
    retry_policy = LoggingRetry(
        total=5,
        backoff_factor=0.1,
        status_forcelist=[ 500, 502, 503, 504 ],
    )
    session.mount('http://', HTTPAdapter(max_retries=retry_policy))
    session.mount('https://', HTTPAdapter(max_retries=retry_policy))

(Based on allowlists and control variables such as the number of total retries to allow, whether to respect the Retry-After header, whether this header is present, and whether the returned status code is on the list of status codes to be retried upon on the presence of the aforementioned header)
