Steve,
I can't speak for Stephane, but I do have a comment. In the example I gave, I was pyramiding by NOT liquidating the first position. Rather, when you pyramid, you ADD to an existing position by adding another unit. So, if your initial unit size were, say, 300 shares, if your profit goes to 1 ATR, you add another 300 shares, now making your total open position 600 shares (2 units). You keep doing this as your profit grows, moving your stop up to be even with the most recent position add-on. That's what I mean by pyramiding. Al Venosa
