On intraday equities, win rate has nothing to do with this discussion at all. Even theoretically he is mistaken on the most fundamental basis concerning the tape. Learn to scale or fail.
I haven't dug any hole f9. The math is correct. Thank you though for trying and also for not being a scaler!
The problem lies not in the maths but in the originating logic. Spare a thought as to the reason why some people scale. regards f9
For most of the systems I have written, having a profit objective--a form of scaling out--weakens the system. The larger the profit objective, the better the system; but systems with NO profit objectives and with trailing stops progressively tightened work best. For those who scalp stocks for a living, scaling out might make the most sense. But for the rest of us, including intraday and longer-term futures traders, and longer-term stock traders, profit objectives make little sense, mathematically.
This has nothing to do with scalping, scaling is how you make 20 points in GOOG, or 10 points in GS intraday -- it is absolutely necessary. By the time you get a "signal" to sell your 2000 shares of BIDU because of whatever silly technical reason, of course you will get crushed at market. Wake up people and stop talking about markets or time frames you have no clue about (not you specifically, sry smiling).
No its incorrect... Sorry, you did not read prior posts... Math itself is not absolute... one cannot derive a definitive solution from math... alone... all variables cannot be known... within any particular dynamic... Newton, like you, was ALSO incorrect that math could be used precisely... or absolutely... the certainty of the 1900's was squashed with the math of Quantum Physics and the foundations of Math itself was found to be shaky and uncertain with Godel's theorem... Newton, believed, like you, that simplicity ruled the universe and the day... He was dead wrong... you are dead wrong... One can derive a flexible solution... but not a definitive one ... it can never be absolute... therefore your 'absolute' point of view is flawed... This thread should be closed... you should get a better education... Have a nice day... <img src="http://www.enflow.com/p.gif">
I have. It's out of fear and greed coupled with a desire to have emotional gratitude and to be able to be "right" more often.
So far so good. Now please read your own words (quoted above) and then return to your example and see if you can spot the faulty logic. regards f9
