*Spits beverage at screen*
If you buy $500,000 worth of stock with your own cash, why would they liquidate you? The most you can lose is $500,000, if all the stocks in yer account drop to 0 and you sell all those positions at 0. Even then, there is no reason for them to "liquidate" you.
How often does that ever happen, anyways?
My utmost sympathy to your screen. I hope you gave it a good wash.
