Conrad,
If we can define rangebound along with up and down trends then what do you think about this idea. When rangebound stop and reverse near the channel extremes. After the first buy make a double sell to create a short position near the top of the range. Then buy twice near the bottom of the range. Once to cover the short and once to go long for the rise back to the top of the range.
In trending markets, it wouldn't SAR but instead it would enter just one direction. For uptrends, buy the dip and sell the rally, thus going flat. For downtrends, sell the rally and buy the dip, thus being flat until the the next rally.
All of this is dependent on identifying the dominant trend or recognizing there isn't any trend but I'm curious what you think about it since it includes 3 possibilities.
