Instead of concentrating on increasing win rate, why not find ways to decrease losing percentages? Study what happened before signal on winning trades, to the left of signal on charts.
Study patterns at extremes then don't trade against them.
My first twenty years were not easy to trade, am a perfectionist, I got into trading as ultimate challenge, my businesses did well enough I retired at 43. All my life been workaholic, having Asperger's helped me see patterns of what's missing or wrong.
Instead of working on high percentage very long term commodity system of selling highs and buying lows, I went to making a horrible low winning percentage system, then learned hedging to make profits when I lost, so I have positive expectancy when trade is placed it will be losing trade on underlying but make overall profits. System seeks percentage nine year extremes, so when high/low entry is found, stays in for 75% of 9 year range and on pullbacks more entries done. Started it in 1991 and improved through the years.
Recently turned off scalping automated systems, all did 5% or less losing %, moved funds to areas that produce larger profits. Have one day trading system automated, runs 24 hours and automating last one, losses 4% and under. Protective stop is $1250, profits less.
Is trading easier after 44 years, absolutely, I understand what happens most of the time. I expect to be profitable everyday, losing days happen cause of averaging down but overall produces more overall.
Most people don't think outside the box, use too many indicators, don't study charting patterns.
One of better patterns is Reverse divergence, Google it.
Wedges with trend, triple bottoms with trend, Head and shoulders with or against trend. Anticipate triangles and get in early, risk less and those do trend line breakout gets your trade to break even stops. Whatever normal signals are, learn to get in early.
Getting older, rather go for larger profit systems, less trades. Scalping/day trading younger person way of life, age catches up.
