thinking about this strategy

I was thinking about my trading strategy, this strategy. Everyone says you can't time the market and that you can never hit the absolute top or pick the absolute bottom. This strategy concedes that fact. We don't try to pick the absolute top or the absolute bottom. What we do however is count on a change of $% to indicate we are past an absolute bottom or absolute top. We buy once an up trend has started, and sell once a downturn has started. If we "think" something is going to take off we add it to our pool and watch it, but only buy once a 5% up-tick confirms our thoughts. I like this strategy. I think it is going to pay off.
