With impending loss of the Fidelity provider, I have begun transitioning strategies to work without it. This involves finding equivalent sources for some symbols, such as symbols for market indices.

I don't know the best way to present this but here's a start...

Notes:
1. Values for .STI.N/^STI.N are similar, but do not match exactly (ex. 7/15/2020: .STI.N=0.79, ^STI.N=0.83)

2. Dot in a Fidelity stock symbol translates to dash in Yahoo's. Example: BRK.B to BRK-B

3. Most Fidelity specific market sentiment symbols are replaced with Wealth-Data like:

Here's dedicated topic to aid transition: Market Sentiment (Breadth) data in Wealth-Data

P.S. At a later stage we may consider adding automatic conversions of symbols across providers (e.g. .DJI > ^DJI, .MB_ADV.Q > $NASDAQ_ADVN etc.). The idea is to create a Yahoo or IQFeed DataSet for stock symbols, a W-D DataSet to transition existing market sentiment symbols and so on. But this is a potential, future task. Automatic conversion will not appear in upcoming release of the WLD Migration Tool.
