How tightly regulated is investment margin lending in the US?

[quickthrowman]

You can get SPAN margin if you have enough money, margin is calculated dynamically based on implied volatility and other metrics. I’m not very familiar with how it works, I have a regular margin account.

Standard margin accounts allow 2x overnight leverage and 4x day trade leverage (must close below 2x leverage at market close)
