Inspect Cached Datasets in Redis for Errors — Stock Analysis Engine 1.0.0 documentation

Tool for inspecting cached pricing data to find common errors. This tool uses the Extraction API to look for dates that are not in sync with the redis cached date.

Note

This tool requires redis to be running with fetched datasets already stored in supported keys

Examples

Inspect Minute Datasets for a Ticker

inspect_datasets.py -t SPY

Inspect Daily Datasets for a Ticker

inspect_datasets.py -t AAPL -g daily
# or
# inspect_datasets.py -t AAPL -g day

Usage

inspect_datasets.py -h
usage: inspect_datasets.py [-h] [-t TICKER] [-g DATASETS] [-s START_DATE]

Inspect datasets looking for dates in redis that look incorrect

optional arguments:
-h, --help     show this help message and exit
-t TICKER      ticker
-g DATASETS    optional - datasets: minute or min = examine IEX Cloud
                intraday minute data, daily or day = examine IEX Cloud
                daily
                data, quote = examine IEX Cloud quotes data, stats =
                examine
                IEX Cloud key stats data, peers = examine IEX Cloud
                peers
                data, news = examine IEX Cloud news data, fin = examine
                IEX
                Cloud financials data, earn = examine IEX Cloud earnings
                data, div = examine IEX Cloud dividendsdata, comp =
                examine
                IEX Cloud company data, calls = examine Tradier calls
                data,
                puts = examine Tradier puts data, and comma delimited is
                supported as well
-s START_DATE  start date format YYYY-MM-DD (default is 2019-01-01)

analysis_engine.scripts.inspect_datasets.inspect_datasets(ticker=None, start_date=None, datasets=None)[source]¶

Loop over all cached data in redis by going sequentially per date and examine the latest date value in the cache to check if it matches the redis key’s date.

For IEX Cloud minute data errors, running this function will print out commands to fix any issues (if possible):

fetch -t TICKER -g iex_min -F DATE_TO_FIX

Parameters:

• ticker – optional - string ticker
• start_date – optional - datetime start date for the loop (default is 2019-01-01)
• datasets – optional - list of strings to extract specific, supported datasets (default is ['minute'])
