If my memory serves me correctly, this indicator is a renamed version of the VQ.mq4 and I see on their Thread that they have improved the original quite considerably. The present Alaskin downloaded from your Thread, seems to behave like in the beginning of the VQ concept. You may want to look into this.
Secondly, I have an ADX Crossing indicator by Amir which I find extremely accurate almost to the point of disbelief.
It outperforms the 2 I have downloaded from your zipped file and I place it here for your perusal and comment.
Best wishes.
