firstly i gotta say i'm not as experienced and well verse in trading as many of the veterans here. hopefully the comments would be kind and constructive but any advice would be greatly appreciated i used to be a mechanical trader but over time (especially recently) i've become discretionary (largely due to the inspiration i got while reading this http://www.eminiplayer.com/2009/06/learning-to-become-successful-trader.html) in the sense that i don't take every trade that fires which has helped me greatly. results as a "more" discretionary trader have been much better. so far everything is fine but i can't keep a worry out of my mind when human judgement is involved, there is bound to be more mistakes? and lack of consistency... at least thats what i think. i was just wondering how could someone be able to constantly "read" the market with great accuracy for long periods of time? i somehow feel that this "method" of trading would be prone to many psychological ups and downs since discretionary trading is largely subjective? (for me its just picking which signals to trade) any advice would be greatly appreciated.
