Rolling the warehouse is truly daring; I no longer have that courage. Previously, I shorted from 29,000 to 25,000, rolling from 6,000 to 800,000, and there were also a few times with a hundred times leverage. I didn't dare to continue after being liquidated. Just last night, I rolled a little, from 100 to over 3,000; I don't have the courage to keep doing that.
