How about people claiming they have PhDs in math when they don't? Shouldn't they get called out?Quote from fletch2:
Agree. ET is 99.9% a waste of time. But maybe if people who go around slinging insults and calling people liars get called out from time to time, they'd behave better.

Cynical? Do you really believe that Fletch has a PhD in math? LOL!!!!Quote from Raystonn:
You're pretty cynical, Trader666. Perhaps having been burned before has caused you to disbelieve every single thing anyone has to say when it might support an argument contrary to your beliefs.
I was about to post a mathematical proof on the subject of profit factors and position size, but you know what...
You're really not worth the time.

I agree with those who feel that Profit Factor is not always a perfect measurement of system goodness. Attached is the output of a 16 year system test with 4800 trades. The "Sled" system looks half-decent to me; you can dig through the output stats to find its Profit Factor.

Quote from Trader666:
Here's what he wrote:That's not what he was doing in that post. While it's true that PF can be improved through position sizing, Raystonn's system is a lousy one to do it with because it trades too infrequently... and for that reason even if those numbers did add up, I wouldn't trade it. So in reality, Raystonn's definition of what makes a good system is more skewed than the OP's. FYI, TRULY experienced traders know that there are ways to improve PF (and Sharpe) above and beyond entries, exits and position sizing. And that those ways should be applied first, before position sizing.
