Pitchfork indicators can be a good way to isolate long term trends over an extended 12-18 month time frame.
Additionally, you can use a pitchfork on a shorter term to give you a feel for price movement in a 4-6 week time frame.
In combination, they can provide a good way to isolate a specific target price/date where you might expect to see a cycle top.
Take a look at my Gold chart and you will see a projected price of 1300 that should occur around March 20th.
I plan to hold my positions until then, and make a decision to either close my longs if the sentiment turns negative, or hedge my longs if the sentiment remains somewhat bullish.
