Trading since 2011 did very good when trading for small profits but lost and still losing when I go all in due to greed and over confidence. One day want to breakeven to recoup years of losses and eventually make money.
I buy many tickers in small lots. This allows me to buy/ sell stocks at-will. And, I sell winners and losers with equal certainty and resolve. I would rather miss getting the highest price than lose potential gains from hoping an up trend continues.
