Quote from empee:
interesting. I have been using 350 day ma's for my systems before the turtle book came out, just because it seemed to be a better indicator (through backtesting) than 200, it gave more trades and still avoided the big selloffs (the ones that occur after a downtrend has started) Maybe they found that as well.
Another similar conclusion he drew (I've seen this in my own backtesting), is that most typically advocated ATR based stops are worse than having large to no ATR based stops at all. In other words, systems with wide stops (large to no atr stop or wide MA period), generally perform better.
Pretty much refuting/clarifying a lot of problems with many authors (van tharp, etc...) advocating 2-3 ATR type stops in their books.
Another great example of theory vs. reality.
