Though the ability to do backtesting analysis of custom algorithms is not offered by IBKR software, historical data is available from the TWS API with corresponding market data subscriptions which can be received by an external third party API application and potentially used for backtesting studies. For information about which 3rd party API applications support backtesting it is best to contact the 3rd party software vendor directly.
