We like to think that trading is an equal opportunity event like the 100m sprint: anyone can get their kit and as the slogan says "just do it" but the politically incorrect truth is that by nature you may not be designed to sprint. You might have slow twitch muscles which will never go fast enough and then there is the giant genetic factor that black athletes have a difference physical design. Fast sprinting might be as far out of your reach as a white man appearing in the Olympic 100m final. The fact is Genetics, Cultural and Gender (GCG) issues divide us and impact the way we play, how we conduct business as much as how we perceive the movement on a chart and think about TA. You can look at the hands of two traders and know if one is more likely to be in the winners enclosure and earning 1000% or more than the trader beside him just because the first trader was cut out for the job and the second wasn't. It's Tough Titty if you have CGC issues and you try to make sense of TA so what do you do? You post a zillion times TA can't work but you won't post charts of your failed TA or if you do an explanation as to why you read it wrong shoots at spaceship level over your head. Examine the evidence: when traders look at the spinning ballerina, many see her spin clockwise while other see her spin anticlockwise http://en.wikipedia.org/wiki/Spinning_Dancer Right and left brain viewers don't see the movement or the same connections and outcomes just as musicians can feel the movement of the melody and understand and predict a complex chord progression while to non musician predicting the next movement is a mystery. Try to get the left brain working in a trader with right brain perception and you get the same results as the reviews for this book.For some it is brilliant to some yet worthless to others, just like the conclusions on TA in ET. http://www.amazon.com/LEFT-Brain-Trading-mindset-technique/dp/0973822228 Everyone is totally convinced they are correct and build their analysis and conclusion from what they see. Try explaining the obvious TA reaction and relationships on a chart to someone who is visually hardwired not to be able to make those connections and it becomes a shouting match - it really is not happening as far as they are concerned. When they spend months investigating indicators they conclude they are nothing but squiggly lines so they do a 80/20 trigger back test and arrive at the profound conclusion they were right. You could train a monkey to do such a back test. Visually they are challenged beyond their ability to ever understand TA.
