Lack of patience on two fronts caused today's losses.
Closed CIEN out early at 10.50 on 10.09 premarket long entry. I knew the fundies, knew there'd be buyers, but didn't let my winners run.
Then jumped into some low-probability trades with exit points excessively wider than usual. Caused big losses.
It's a fact that newbies are their own worst enemy when trading. My major weakness is lack of patience (aka discipline of opportunity) and mastering that will continue to be my focus.
