"Analyse your markets and lay out your strategy and tactical moves in advance, and in privacy. Don't ask anyone's advice, and that includes' brokerage advisories, tips and even well-intentioned market gossip. And, don't offer your advice to anyone else. You shouldn't care if Shearson is buying ABC or if Salomon is selling XYZ. You should stick to your objective analysis and market projection based on whichever method or technique has proven viable for you; and you should revise that strategy only on the basis of pragmatic and objective technical evidence. Such evidence could be a signal from your chart analysis, your computer system or from the margin department, which reminds you that your position has moved adversely and that your account has become undermargined."
