Hi Christian,
On 7/16/18, Valeant Pharmaceuticals (VRX) started trading as Bausch Health Cos. (BHC). Since BHC is in the symbols list in the algorithm, a backtest will look for any options data whose underlying asset has ticker VRX but then will look for the same options data but with the ticker BHC once the change is affected. If you run the attached code, you can see how the algorithm will take the user-provided symbol and if there has been a ticker change, will find and use the original until the change has occurred and then proceed with the updated symbol. The data type SymbolChangedEvents provides information about ticker changes and can help debug similar issues.
The first type of option ticker SMH 180817P00105000 contains details about maturity date, type of option, strike price, etc. When an options ticker is in the format XYZ | ABC it means that it has an underlying Option / Underlying Equity.
