Hi, I have a question.

Assume I have data for two forex pairs (EURUSD_custom, USDRUR_custom) from some data provider.

I want to use both of them in one strategy for Lean, How can I do this, if in OnData function I can receive only one of them (e.g.  public void OnData(Bitcoin data),  OnData(EURUSD_custom data)  etc. )?
