Margin policies can be a little confusing to investors who have never used a margin account before, experienced traders, and just anybody else not a big fan of math. And as margin policies can vary from firm to firm, let’s just say confusion reigns.

But at TradingBlock, we maintain exchange minimum margin requirements to minimize the confusion (as best we can) and help our clients maximize their portfolio buying power. If you ever have any questions regarding margin and our margin policies, please contact our Trade Desk at 1-800-494-0451.
