Do you know what brokerage firms offer: - the best or highest interest rates - the best or lowest margin rates Say any firm which you think the "best" in your own definition. Thanks.
If you're talking about a retail account, just leave your money in short term treasuries. Solid rates and still get at least 80% buying power. If you're talking about a prop account, I think the difference in interest rates between firms would be negligible (maybe 1% difference).
Here's reail firms forum, so yes, I'm talking about retail firms. What retail firms offer the most attractive interest & margin rates?
