If don't know about technical analysis, maybe people will look information in forum like this. Collect prediction from people and then make my strategy from it. That is why i very agree with people should learn technical analysis.
If you are trading with other people predicting then you will not go further, make your own analysis and come to a conclusion rather than trusting a third person and that is the case with every financial market. I do not trade with technical analysis alone i just monitor the market trend and make my own decisions when i am in the mood to trade in the short period.
