Daytrading is not for novices.
You need at least four monitors in front of you to watch the candlestick draw before your eyes with hundreds of thousands data in a fraction of second, constantly changing. The best way to put it is like the pulse of the market. You see the stick inflate, get longer, get fatter, make the turn, all that in less than a second, and according to that curve, you click to buy or sell instantly. Japanese Candlesticks help you recognize the patterns of that curve and you know what every single one, black or white candlestick means, their plunge, their reversal etc... 90% of the time they are right.
