What it is

This is a Wealth-Lab static and fundamental provider for free daily data from Tiingo.com. The feed makes available the data for 37,000 U.S. and Chinese (Shanghai/Shenzhen exchanges) stocks, mutual funds and ETFs.

If you're familiar with the built-in Yahoo! provider, you're going to get common with the Tiingo provider very quickly. Its features include:

Setting it up

Before you're able to download any data, you have to register a free account at Tiingo.com, verify it (click on link you get by email) and type in the credentials in the Data Manager's Tiingo tab that appears after installation of the extension and restarting WLP/D.

Working with Dividends

The Tiingo Fundamental Provider always returns split-adjusted dividends for a chart's dividend popup as well as when accessing the "Dividend (Tiingo)" fundamental item in Strategy code. While the dividend adjustment factor maintains proper percentage relationships between prices, it's possible that new dividends affect previous backtest results (trades) for some strategies. Disable "Apply dividends" in the Backtest Settings Preferences when using dividend-adjusted data for backtesting. If you don't, the dividend effect could be duplicated in the Performance results, especially for the Buy & Hold Strategy.

Data Editing

To edit bar data, open a chart and either:
  1. double-click the bar to edit, or,
  2. right-click the bar and select Edit Bar Data.

When editing Tiingo data, be aware of the Perform Dividend Adjustment selection since the chart values will reflect this adjustment. Deselect this option and refresh the chart to edit raw price and volume.

With the "Ignore splits and dividends which fall out of the range" option selected (disabled by default), only deleting bars is possible.
