Several years ago before I had found a way to demonstrate this methodology, I had a meeting with a former CEO. I had mentioned to him the idea of using something like this methodology to trade against a longer-term position. Most longer-term position traders are most likely holding a LONG position. So, if you could determine the short-term direction, you would be able to trade against that position and make small gains as the market went against your longer-term holding.
The idea is not to be right, but to be on the right side of the market.
