Here is a paragraph from Scott Carney’s ‘Harmonic Trading Volume One’:
It is important to note that the initial point (X) utilized an “intermediate point” to begin the pattern. The intermediate point, although not the clear low from the prior’s day action, was defined well enough to establish the appropriate alignment of Fibonacci numbers in the structure. This structure illustrates the importance of the relative alignment of ratios to define a pattern. The formation of various patterns do not have to initiate from an absolute low or high. Although XA legs that are well defined typically originate from an extreme price level, the symmetry and validity of a particular pattern are more dependent upon the segments that comprise each structure. In this example of the ES, both the XA and BC legs were distinct and effectively outlined the pattern’s completion, despite originating from an intermediate support point from the prior day.
I am not knocking TMB’s statement that the X point should be a price extreme, I merely wish to show that it’s not the only valid point. If you wish to use only extreme price points for your X placement, I can’t knock you for that. After all, that’s what TMB does and he certainly knows his stuff and is making excellent trades. However, I feel you may be losing out on several more trading opportunities by limiting your X placement in this way.
Anyone is entitled to take an established trading style or system and alter it in any way for their own purpose. TMB has not claimed to be trading a Scott Carney style or system, merely a harmonic one, so there is absolutely nothing wrong with his techniques.
Among many other things, Scott Carney is the one who introduced the 0.886 fib level to the trading world, so if you see this being used or mentioned by any other website or trading system, know that it has been ‘borrowed’, as have a lot of other harmonic ‘traits’.
I would highly recommend Scott’s three books. They will give you a thorough understanding of harmonic trading and a solid foundation from which to build your own trading system. Then I suggest following TMB to see how harmonic trading can be a solid and profitable style of trading. Even though I have read these books, I am still keen to follow this thread and TMB, as there’s nothing like seeing the art of successful harmonic trading in progress. And this I feel TMB accomplishes with style.
