I was recently talking to some colleagues whom I would classify as between 'beginner' and 'intermediate level' traders. We got to talking about trading in general, and the options markets in particular, the challenges facing beginner and intermediate level option traders. It was an interesting discussion, since the same problems seem to be cropping up several times (although worded differently). I thought I would ask in here to find out if other traders have faced (or are facing) the same problems. Not wanting to bias the results, I have deliberately not spelt out what the common problems/pit falls are, but it would be interesting to see if the same problems come to the fore again. So, what are your top issues and challenges with trading in general and option trading in particular?
