I just noticed that Yahoo! Finance is still not accounting for the special ABBV share dividend in the ABT data. I can only suggest that users apply an on-the-fly script adjustment to the data as shown below.

Although this works for any provider that does not account for this dividend in their data, it will create a minor peeking effect on non-dividend adjusted data (like Fidelity) if you include dividends in the Backtest Settings. In this case, previous cash dividends are not adjusted, and therefore a backtest on ABT will be rewarded with approximately twice the dividends in real life.

A better long term solution will be to make the data adjustment in the binary wl file, which I will get to eventually.
