I keep reading all these money management tips by various pros and trading coaches, and they sound logical but make no sense, yet everyone seems to buy into them. If you go in with multiple cars and try to scale out, especially if it's at a reversal point that may or may not happen (most people using indicators do this), you take the worst exposure when you are the most vulnerable.
I like to do what I do on the beach: I dip one toe, and pull it out quickly if it doesn't feel good. If it does, I enter with both feet. In other words, risk 1 car, then add more when the trend is established, and more if it strengthens. That way you have the most cars in when the going is really good and just flatten to exit them quickly with the most profit when you see a reversal signal. If the trade doesn't work, you take a small loss on only one car.
