Are the conditions really correct?

Hi, this is my first contribution to Wikipedia. I just have a question regarding the conditions stated in the article, reproduced below.

if ((High[j – 2] < Close[j - 7]) && (High[j - 2] < Close[j - 8]) && (High[j] < High[j - 5]) && (High[j] < High[j - 6])) $n_{j}=0$

  else $n_{j}=1$

if ((Low[j – 2] > Close[j – 7]) && (Low[j – 2] > Close[j – 8]) && (Low[j] > Low[j – 5]) && (Low[j] > Low[j – 6])) $m_{j}=0$

  else $m_{j}=1$

I see that you compare the High at j with the High at j - 5 and j - 6, as well as the Low at j with the Low at j - 5 and j - 6. DeMark does not do this in his 1994 book (cited in the References of the article). Rather, he compares the current High with prior Lows and the current Low with prior Highs. It is true that he compares the current Low with prior Lows on page 95 of the book, but this appears to be a typo because he compares the current Low to prior Highs in the sample code on page 98. His description of the indicator on page 25 of his 1997 book "New Market Timing Techniques" agrees with this code.
