“ The large operator does not, as a rule, go into a campaign unless he sees in prospect a movement of from 10 to 50 points. Livermore once told me he never touched anything unless there were at least 10 points in it according to his calculations.”

So writes Richard Wyckoff, the legendary trader who in the 1930s wrote a manifesto that gained him a cult following on Wall Street.

His 1931 book, “The Richard D. Wyckoff Method of Trading and Investing in Stocks – A Course of Instruction in Stock Market Science and Technique,” is somewhat difficult to find these days ( not impossible ), but even in 2013, hedge fund managers still swear by it.
