I have a question about the so called "survivorship" bias.

When backtesting strategies I backtest only symbols which exist at the moment. So I do not backtest symbols which where delisted in the past. Does anybody knows how to get stockdata of delisted symbols?

There is a similar problem with for example the sp100. Which symbols where in the SP100 in 1999?

How do you solve these problems with wealthlab?

Thanks for your answers
