Modified on 2018/03/31 06:43 by Eugene — Categorized as: Providers

This is a static and streaming provider that downloads daily and intraday historical price data from Google Finance.

Intraday backfill

Starting from v2011.01, intraday historical data can be downloaded from Google. Supported time frames: 1 minute, 2 minute, and 5 minute. The data loading depth is only 2 months for 5-min bar scale (and less than that for 1- and 2-minute charts).

Streaming

Starting from version 2011.01, the provider supports free Streaming intraday and daily data. To enable, open the Wealth-Lab's Preferences dialog > "Streaming Data" and tick "Google Streaming Provider". Effective v2016.06, provider supports streaming updates in Accounts window for Paper Trading.

To conserve bandwidth and reduce server load, partial bars are updated once every 10 seconds for snapshot quotes.
