This makes a lot of sense. I remember a day when naturalgas prices were falling. I had been bullish in the morning -- and right -- as the early trade was higher. But as the day progressed, a weather pattern changed and the sellers took over.
I foolishly decided to defend my position. (That's a very bad idea, as no one is bigger than the market -- a golden rule to successful traders). As prices tumbled, I added to my long positions, assuming that I would need only a small bump up in price to "get back to even."
The price continued to fall, and I continued to add, still only needing a small turn north in price and I could get "back to even."......
