If you know the Turtle System you will likely have the answer. I bought the stuff from the www.turtletrader.com a while back.... How to pyramid correctly? If I understand some of the calculations leading upto this point; Assume $10,000 to trade ATR = $4 Assume 2% risk Therefore risk = $200. # of contracts = $200/$8 (2 ATR) = 25 contracts. 25 contracts = 1 Unit Understanding the table; Unit # 1 is my initial position. Unit Accumulation of 2 ATR = what I used to establish the Unit #. Price = $100. Final Stop = $100. New profit needed to pyramid would then be 1/2 ATR or $2. Are you suggested then that in the second line of the table that as price increases to $102 ($100 + 1/2 ATR) I would accumulate an additional 14 contracts ($200 risk/3.5 ATR = 14 contracts)? Am I always basing my risk on the $200 (in this case) when I calculate the number of additional contracts to accumulate?
