You misunderstood. He isn't blindly adding to a losing position. Once he sees he is on the wrong side he will immediately reverse direction and double the size so that way it only has to move half the amount in order to be back into profit. I think we as traders have all seen this. A position is going against us and we keep hoping and praying for it to turn around. Maybe we add lower down for longs since this will improve our average price but in the back of her head we know that the selling doesn't look good. Imagine for a second if you had the balls to realize you're wrong and immediately change direction and hence get into the trend.
There were some posters who said that on Thursday and Friday they kept shorting the market. And yet it just kept on rallying. Imagine if seeing this they had the balls to reverse their position and increase their size. It would clearly have covered any losses and made profits.
As stated a few times in this thread...profitable traders are not using 100% technical analysis...
They are also dependent upon risk management, position size management, psychology et cetera.
The guy you're talking about is using position size management in position reversals or re-entry into the opposite direction by doubling the trade size regardless if overall he's profitable in those types of trades.
On another note, I'll repeat the issue in this thread. The OP specifically asked for someone to Prove to me that Technical Analysis Works...he then begin to move the goalpost in his opening post by equating it to "super-rich" investors. His exact words in the thread title.
- Simply, not only do you need to prove that TA works...you need to be super-rich too from the TA.

Yet, some in this thread have shown up to pretend he asked to Verify You're A Profitable Trader and that's not what he's asking because the two requests involve completely different types of verification.
- Simply, verifying that you're profitable does not verify that you're using technical analysis nor does it eliminate the importance of other edge's in your trade method such as risk management, position size management, psychology...
It explains why two different traders using the exact same TA method while trading the exact same trading instrument can have completely different trade results...one is profitable and the other is a loser.
That's another way of saying this is that it's not all about technical analysis. The real edge is the trader and TA is then just a tool for that trader as much as a hammer and nails is to a construction worker.
