Quote from ssternlight:
I'm glad you found an approach that was optimal for you. My point was the discussion here has not shown any one exit strategy or another to be superior. The most I can conclude from the discussion is that no one has presented a convincing argument for one side or the other -- which is pretty typical of ET discussions.
Having said that, the examples posted by BS12 are flawed. That's not to say that the strategy is flawed just the examples don't prove the case.
As for "talking what I know", I've traded systematically for over a decade now and have tested all kinds of ideas with many different types of money management. My own opinion is more along the lines of different horses for different courses. Generally speaking, I find the market tends to school those who come from an absolutist point of view on just about any approach.
Just my $.02
I couldn't agree more. You haven't seen any statistical proof arguing either side from me simply because I haven't done any yet. I am not arguing for either camp at the moment, however, just that I don't think the logic presented in B1S2's example is sound. I would be happy to be proven wrong and learn something, but as it stands, I don't believe his arguments are supporting the statement "scaling out is inferior behavior".
As for which one is better, I don't know. I do what I do for various reasons, one of the biggest is preservation of capital, both mental and financial.
TNG
B1's method of 'all out' is not suitable to a lot of traders for various reasons especially intraday based, one of them is a trader's ability to find a good entry point, though uncertainty about where to exit, therefore a scale out is being used, partial closure warrants locked profits with exit at entry, etc. B1 is simply saying that a strategy that halves a potential profit though keeps a loss at 100% position size is a flawed "inferior" way to trade. I both agree and disagree with his statement. it's certainly is not an easy debate as all discussions have to be relative to a specific situation, not to multiple/different methodologies. What B1 does, he does very well, intraday high leveraged position trades would be very difficult to achieve using 'all out' method, unless profit target is relatively tight and/or trailing stop used. IMHO.
