im 36. used to b stockbroker. have dversified portfolio, of all timeframes, disciplines, sectors & markets. intra-day, i play textbook & higest-quality technical & fundamental set-ups. i look for 3:1 Risk/Reward. stocks $10+, 500k+ daily volume.
Often there is no lesson to be learned, each stock is unique.
Stocks go up and down, it is what they do. Run with the bulls, short when it gets nuts.
Tired of most technicals, volume and news is all I care about.
