After you bulk download the US Index Options dataset, new daily updates are available at 8 PM Coordinated Universal Time (UTC) two days after each trading day. For example, the minute resolution data for Monday is available on Wednesday at 8 PM UTC. To unlock local access to the data updates, open the Pricing page of your organization and subscribe to at least one of the following data packages:

• US Index Options Daily Updates by AlgoSeek
• US Index Options Minute Updates by AlgoSeek
• US Index Options Hour Updates by AlgoSeek

You need billing permissions to change the organization's subscriptions.

After you subscribe to dataset updates, to update your local copy of the US Index Options dataset, use the CLI Command Generator to generate your download command and then run it in a terminal in your organization workspace. Alternatively, instead of directly calling the lean data download command, you can place a Python script in the data directory of your organization workspace and run it to update your data files. The following example script updates all data resolutions:

import os
from datetime import datetime
from pytz import timezone

# Define a method to download the data
def download_data(resolution, overwrite=False):
    print(f"Updating {resolution} data...")
    command = f'lean data download --dataset "US Index Options" --data-type "Bulk" --resolution "{resolution}"'
    if overwrite:
        command += " --overwrite"
    os.system(command)

# Update data files
END_DATE = datetime.now(timezone("US/Eastern")).strftime("%Y%m%d")
latest_date = sorted([f for f in os.listdir(f"indexoption/usa/minute/spx")])[-1].split('_')[0]
if latest_date >= END_DATE:
    print(f"Your data is already up to date.")
else:
    download_data("minute")
    for resolution in ['hour', 'daily']:
        download_data(resolution, True)

The preceding script checks the date of the most recent minute resolution data you have for SPX. If there is new minute data available, it downloads the new data files and overwrites your hourly and daily files. If you don't intend to download all resolutions, adjust this script to your needs.
