Thanks @Petra.

Renaming History files: Will obviously work, but as a general practice would become a housekeeping nightmare! Do we really want to proliferate files whose data doesn't match their name? It would seem there has to be a better way. Shouldn't the History file be pulled based on the Symbol name, as when getting the data from the Broker?

Leverage: As always, a confusing topic. Are you talking about the Leverage the Broker may apply based on account size, type, whatever? Or are you talking about leveraged ETFs? If the former, and the latter is used, is then Leverage multiplied to 4x, 6x, whatever?

Thanks.
