You have a valid point,a point which was cleared by my teacher in my first class with him.
CLOSE YOUR EYES TO WHAT THE WORLD IS REVEALING,BE DEAF TO THE TV CHANNELS AND STOP READING ECONOMIC TIMES.STICK ONLY TO THE SYSTEM WHICH YOU HAVE DEVELOPED.
Ofcourse do the readings of dailies and watching tv,but after ur daytrading job is done,not in the market hours.
If you want to survive as a daytrader,as the title of the thread is indicating,then you must stop thinking about what other people,which includes any other layman to expert analyst and experienced traders,are saying.
Daytrading is a business and it should be learnt with great care and time in hand.
