Some imp points from guidelines related to trading by him said to have been published in one of his newsletters.
> Dullness is followed by a trend. Keep a note of direction in which volume increases during that period – that is the likely direction of breakout.
> Go light when market direction is not certain. Wait for clearly defined moves and concentrate on them. It will help you to prevent unprofitable trades
> Buy Strong and sell weak. Trade trending markets.
> Whatever else you do - limit the losses, and ride the profits. (Every experienced trader would say this again & again. Yes, easier said than done - but at least read it again & again)
