Quote from chewbacca:
getting stopped out is basically forced liquidation
now think about it why the f--k would you allow yourself to get liquidated - unless your were fighting the trend, overleveraged, and undiversified from the very start........or you had zero confidence in the position from the start and you just put it on for the action.
it certainly helps to qualify that statement to the vehicle of choice...
now if you were talking mark to market futures trading, where intraday movement can wipe out your account and leave you owing the firm, then your arguement needs to be tested in real time and then come back and report your findings,,,
almost certain that you will curse your own words!
however, if you were discussing equities, where you actually own something, instead of all the various forms of derivatives (options, futures, options on futures, bonds, debt instruments (swaps, etc.) and some other exotics) then your intial claims do have their basis in fact.....
however,
if you need a bathroom break, a lunch break, a tele break, a check the printer break, then stop losses allows you to take up your seat on the trading desk after the break, otherwise, they will be dusting off the chair and closing what's left of your account and getting someone else to sit there because volitility ensures that naked (unprotected) positions have some sort of cap on market risk, either through options on the underlying index or equity or through some other hedge, but to just be short, say GOOG, when it does one of its +$35 point moves is sheer stupidity, without having some sort of cap or stop loss in place....
