Happy new year! No, I have both made money and lost money day trading. I have nothing against it and think its great from the standpoint of added liquidity and volatility in the markets.
However, for most folks, it is a losing proposition right now-- HFT etc has taken any edge that once existed--- obviously, some traders may have found edges working now short term-- I have no way of knowing but my experience and contacts tell me that its very unlikely. Could things change that make day trading a worthwhile endeavor-- sure-- no one knows what the future holds.
With this said, I maintain that the evidence proves that day trading is not monetarily worthwhile for the 99% of traders. Is it worthwhile for other reasons like fun, sport and hobby, video game, gambling--sure!! best wishes to everyone, day traders included! surf
