Amazing post, and I fully agree. Upvoted! It perfectly encapsulates the problems I am having with trading.
Currently, my focus lies in Forex trading, and I can't seem to do anything other than breaking even. A few months ago, I created a demo account with 1000 euro on it. Today, that account has a balance of 991 euro.
The current strategy i'm using is:
Simple breakout trading
Just drawing a trendline across multiple tops (in a downtrend) or bottoms (in a uptrend). If it breaks, I wait for the price to retest it and form a pattern, from where I place the trade. I use Fibonacci to measure take-profit levels, and place the stop-loss just behind the pattern.
It sounds like you're not using math. Implementing some further assessments of your trades would likely really help you.
