How can I be liquidated?

[belisarius1043]

The exchange I trade on gives me 20% of my principal if I'm liquidated. I profit from this by hedging on another exchange. Tell me the easiest way to get liquidated, but for me to profit, my trade on the other exchange needs to be profitable. In this case, I profit 20%.If I'm going to open a $1,000 short position, I'm also going to open a $1,000 long position on another exchange, and my money there needs to be liquidated and reset to zero.
