It's certainly possible. I do it. My partners Chris, Bo and Allen do it. You see, your reasoning that "if you have an emotional stake in a certain position it's difficult or impossible to offer objective analysis and/or advice concerning that security or market" is not necessary correct. I am not saying this factor has no place whatsoever, obviously having position impacts trader's thinking. But let me offer you somewhat different approach to this, one that governs my action. Any trade I take is based on certain setup. I do not get emotionally attached to a stock, I do not experience any of those feelings impacting trader's objectivity. It's simply "here is setup, it works or not. If it does I take my profis on exit signal. If it doesn't I take my stop at pre-determined level". With this attitude you have no problem reporting your trade as it occurs or commenting on trade develoment and your decisions. You do not feel the need to be right every time in front of your audience because the core of your teaching shows people that you play the probabilities and you can and do lose on this or that trade. When your stop hit you simply take it and move on. When your profit objective is reached you take a bow and move on. You are not trading to prove anything - you simply trade for a living day after day, just doing your job best you can. Please, do not take my words as a claim that it's easy state to achieve, I am not trying to make it sound easy. But that's what I came to in a course of 7 years of trading, and trading gods know it was not easy road. I am sure plenty of successful traders will relate to the description above.
