Quote from MrPowerBallad:
For the most part, yes. In trying to figure out why certain signals look much clearer from the short side rather than the long side (trend pullbacks being a good example for me), I've concluded that the bias must be buried deep in my (our) subconscious and/or genetics. It does make some sense when you consider that we witness things falling everyday throughout our lives (leaves falling from trees), but how often to we witness things shooting up toward the sky -- unless you visit Yellowstone, not much. Maybe there's a better reason, but for now, that's the best I can come up with.
Also, if you are really monitoring all of the contracts listed in your first post, then I don't think you'll have a problem only going short. But if you're only monitoring one or two at a time, then you may not get as many signals as you need. I usually monitor about 3 contracts.
