Quote from AFJ Garner:
In a profitable trade, TF takes the middle out of a trend - it will go long after the market has started moving up and will exit after the market has started coming down. The reverse for a short.
A losing TF trade may well (in retrospect) have bought at a high or shorted at a low. But its a number game as you should know.
Try reading Perry Kaufman, Way of the Turtle, or some other book which explains the mechanics of TF. Out of all the books I have ever read about trend following the most helpful was: Chuck Le Beau and David Lucas in their book Technical
Traders Guide to Computer Analysis of the Futures Markets.
If you want to understand TF, I fear that you have to get technical.
