You've touched on what I believe is the root cause of my challenges. I don't have a dedicated system. I wait for certain well-known patterns/setups, etc, and I trade them accordingly. I use simple indicators like trend lines, support, resistance - identify consolidation ranges and trade as the mark-up occurs (chop range is broken) , try to spot areas of consolidation, distribution, etc... I need a systematic approach so all thoughts and emotions are taken out of the equation. I intra-day trade, so I may be in a trade from 2 seconds (quick scalp) to two or more hours. I do not hold overnight, but I will in trade pre-market and AH if the opportunity is there.
I've read so many books and I've spoken to so many people on this forum and elsewhere. I am starting to doubt whether it is even possible to obtain consistency while intra-day trading. This is by far the most challenging venture that I've ever tried. I will not give up, but I've certainly lost some steam...
I also have my own challenges (fear, greed, hope) which I am continuing to work through...
