another thing to add to take out the bias in a pivot is that you dont draw a set of median lines until "after" the pivot is made... really this is true for ALL charting programs... whether its Elliot wave, fib lines/spiral/circle/wedge, gann box, xabcd, or time based patterns is that they are all based on proven pivots and only then are the tools used. when you try to place the tool ahead of a proven pivot you will get sporadic results. 

the only way to find a pivot is to watch for sellers or buyers to be broken in the correct timeframe OR look for repeatable patterns surrounding the past few pivots.

nothing is easy and at best with markets you are sill left to increased odds.
