Note: I limit my short trades to 25-30% of capital (not including margin), and only short QQQs (don't like options for reasons stated here by syl)..on rare occasion, (this may be one!), I will go 50% short...as a matter of fact, if we ramp hard from here, likely scenario.
So I have plenty of gunpowder, but for me, 25% (of capital) is a "full" position short..
