Trading is something more risky and for successful future in trading one should use his active mind for taking decision and if one don't understand about the price then how he will be successful in trading while being drunk. I think this activity is not good and we all should avoid this behavior. A successful man is one who concentrates on his goals while being drunk cannot be aware of his goals. May be sometimes he do some buying and selling which becomes successful for him therefore success depends on his mind and thoughts but in reality it's not  good behavior so we should her rid of such behavior as soon as possible.
