As a forex nebie in London, I have looked at the Turtles. By defination they were quite long term traders, compared to us intraday wallahs. You cant put those turtle principles into short term trading and hope to see it work. They used large amounts of OPM to trade, so the % profit may have been small as aratio, but the £$ amounts were big.
They were right to be trend traders though, irrespective of time frame.
No software or system can replace knowledge and discipline.
The Tao of trading is Price Actiom w/ Volume. Enjoy...
