Gone through it and nothing special. The only thing worth to mention is what I already know. It is scaling in when you are in profits. They used the word pyramiding but the author meant that with a 30 pip trailing stop e.g. he would double he is initial position size every 30 pips when the market moves in his favor (and not adding half size of it like it is common on pyramiding). It is just the law and power of compounding. That is why you also should never add to a loser. All other things mentioned in this pdf are highly questionable. You only need to ride a trend with scaling in and your trailing stop. But the question is still open how to find those trends where you can make a fortune. It is not solved or answered sufficiently in any way in this pdf thread. But that would be the other main key.
