When combined with other indicators or strategies, I find that this increases their accuracy when used correctly. For those that believe in price action, this might be worth a try. The book has only a brief section on wicks but it is one of the most interesting ideas I found. The book likes to include a in its indicators with a certain length to provide a smoothing type of effect or a sort of extra indicator for the other to be above to give off quicker signals at the cost of accuracy. For this indicator it acts as a smoothing type effect which I put in because it is hard to see the slope and direction of where the moving averages of the wicks are going. The type of moving averages to use and the correct lengths are questionable and are not explained well in the book. If anyone can figure out a good use for this or know better settings or tips, please let me know.
