NEW YORK (TheStreet) -- Natural gas futures have been on a tear in recent weeks. The market has been trending higher on a steep angle but it is now showing signs of cracking.I think many people have been wondering just how much natural gas has left in the tank. Although the market is trading well off its 2013 lows, the fact is that the market remains very well supplied. Now don't get me wrong -- I think the future for natural gas looks good. That being said, trading should not be based on trying to predict the future, but rather trying to take advantage of what price is doing -- nothing more. I am a big fan of trading chart patterns and have found them to be very useful. In terms of the current natural gas market, I do not intend to go into great detail about the market fundamentals. Fundamentals don't pay -- price does. Looking at the June natural gas futures contract, it appears to me that the market is putting in a double top. This is generally considered a reversal pattern, and in this case it could be a bearish topping pattern and at times can provide potentially good trade signals.
