I strongly believe that most TA is entirely useless for Bitcoin at this stage. The trading volume is too small.
Trading volume is not important if the price goes in your direction.
Which of the two would make you more happy:
a) earning 5% at big trading volume, or
b) earning 50% at small trading volume?
If you answered b, then you should never worry about what you perceive as ''small volume'' again.
In addition, the Bitcoin market is subject to price manipulation to a greater extent than a lot of more widely held securities.
What do you mean by ''price manipulation''? Does MtGox display wrong prices? Are these prices non-execution bogus prices or what?
