That may be true AH, but when the markets are open and have high liquidity, what stops either the trader or broker from closing out the position?

Not to belabor this, but The broker doesn't take on a loss for closing out my position. The trader takes on the risk. I assume the margin requirements act as buffer to protect the broker, and that they would apply equally to options and Futures.
