Does anyone know how to convert an IBKR paper trading account's fee structure from Fixed to Tiered? There appears to be no obvious settings to change it. Seems odd that there wouldn't be a way to change it, but maybe they simply don't want to simulate third party clearing house fees.
Too many exchange fee variables which can't be accurately simulated in a paper account and thus not really worth it as the paper trader is there test functionality and tools. In short, there are better uses of resources.
