I have been day trading for 2 years, before that another few years of swing trading. Recently i have been losing small, but also winning small amount, account never increase much, not swinging so big amount, partly because i have been hit by sudden big unexpected loss, but did recover the loss. I realise every strategy has a loop hole, no matter what strategy u used, u can be profitable for a while, then hit by sudden unexpected loss. Size is of course a big factor. So is it a waste of time trading?
