Been studying technical analysis for more than a year and do some work for a investment company for daily forex market movements.
Doing analysis for longer than i have traded, so im still developing trading skills, my biggest enemy being my own trading psychology and self sabotaging behaviors. Price action is my main analysis tool including time, trend analysis, fibonacci retracement for wave correction, classic support/resistance and some moving averages like 50, 100 and 200 EMA and simple market structure patterns like trends and consolidation patterns like the article you have written.
One important factor that is not mentioned in your article is time. You want to see those patterns on a higher timeframe for them to have a higher probability of working. And people who use technical analysis for timing the market also need to learn about risk management and trading psychology. Every one has their own weaknesses, but first you need to find out what those are. Trading demo accounts takes off the edge for controlling emotions while trading, so i would suggest using extremely small amounts when starting and building up your risk tolerance as you learn how the market moves.
