Quote from GTS:
I was trying to allude to the fact that the person that scales out has already chosen two different exit points (mid-point and final point) and one of them is clearly superior to the other and that that trader should learn over time which one is better and then going forward exit the full position at that point (which ever one turns out to be more profitable overall).
What is the basis for your claim that "one of them is clearly superior to the other"? Isn't it quite possible that the optimal position size up to exit point 1 is to have a fully margined long position; but that between exit point 1 and exit point 2, the optimal position is to be long but with a smaller more conservative position?
For example, you may have a stock in a slow steady uptrend with minimal retracements, the stock is continually ignoring bad news and responding well to good news, the stock inches up on down market days, and is up 3-4% on up market days. You identify this as powerfully bullish behaviour and get long on margin. Later on, the stock is getting close to its earnings release, and the price movement becomes a bit more volatile as people try to decide what is likely to happen with the earnings. Normally, you never hold a really big position going into an earnings release - yet this stock is now your #1 holding by size due to the large capital appreciation.
So, do you expose yourself to the risk of a huge one day drawdown in your portfolio, if the reaction to earnings is negative - thus violating one of your cardinal trading rules? Do you completely get out of the stock, even though your analysis & expectation is still bullish - thus giving up on a probable profit? Or do you accept that, whilst still a good position, the risk has increased noticeably, and therefore put on a position size appropriate to that new reality?
According to you, one "exit point" is clearly superior to the other. You are therefore claiming that taking on insane levels of risk, or passing up an expected profit, are superior to taking on a sensible level of risk and exploiting a profitable opportunity. How can you justify such a view?
