"...it would be folly to change the stop so that the risk is increased. This, while customary with the public, is something a tape reader seldom does. Each trade is made on its own basis, and for certain definite reasons. At the outset the amount of risk should be decided up, and, except in very rare instances, should not be changed, except on the side of profit. The tape reader must eliminate, not increase his risk."
"A market which swings within a radius of a couple of points cannot be said to have a trend, and is a good one for the tape reader to avoid. The reason is: unless he catches the extremes of the little swings, he cannot pay commissions, take occasional losses and come out ahead. No yacht can win in a dead calm. As it costs him nearly half a point to trade, each risk should contain a probable two to five points prfot, or it is not justified."
"The ordinary tip-trading speculator gulps a point or two profit and disdains a loss, unless it is big enough to strangle him. The tape reader must do the opposite-- he must cut out every possible eighth [of a point] loss and search for chances to make three, five, and ten points. He does not have to grasp everything that looks like an opportunity. It is not neccesary for him to be in the market continuosly. He chooses only the best of what the tape offers."
