The guy owns a brokerage company. He does the morning market opening as a way of advertising.Perhaps you would like to explain some more.
If he is truly an experienced trader, he knows that it doesn't matter how sure you are about the outcome of a trade. He was trying to take credit for an event that he forecast and had a high degree of confidence in. If you have such high confidence, why not risk 10% or 20% of your capital as a minimum? If you're not willing to risk even 5% of your account on trade, this means that your confidence level in the trade is not that high. Many people say risk no more than 2% per trade, so 5% might be on the high side, but I think still very small for a trade you feel very confidence about.
The fact of the matter is that because he is a losing trader (hence why he teaches), he knows the trade can turn out to be a dud regardless of how strongly he feels about it. So its rather dishonest to now claim how sure he was about a trade that ended up working out when he didn't have the balls to go all in. Its extremely easy to wait for something to happen and then state how sure you were of it happening. But if you put 20% of your account on the line, this shows a strong conviction, not after the fact blabbering.
The fact is he put out a number and it was hit to the exact tick 4016.25 on reversal. I just started listening recently, while I do others things, and IMO he knows his stuff.
If you feel differently or that he has an ulterior motive (who in this world doesn't?) ignore him. But as for the size trade he should or shouldn't put on, unless he divulges it, none of us have any clue what that is and are bs'ing to hear ourselves talk.
