A privilege to sell a certain number of shares at a fixed price within a given period of time. "A SPREAD." When an operator buys or sells both a "put" and a "call." "ON CURB." The private dealings made outside the Exchanges. A curb-stone broker is a familiar figure and carries on his business every day in Wall Street. "INSIDERS." There are two classes of Wall Street men known as "insiders." One is a class which is really inside. Officials of Corporations, of banks and Trust Companies and wealthy financiers who really control the properties dealt in the Exchanges are really "insiders." They control the market, but never give out under any circumstances any information, and in most cases they do not know themselves just what they are going to do from one day to the next. The other set of "insiders" are those who only make the "lamb" think they are on the inside. They never have any money of their own to speculate with, and they sell their "knowledge" to outsiders for fraction profits when there are any. They advertise and give out their pretended information, and have it sent out all over the world, knowing that every city and town may be depended upon to produce "lambs." BUCKET SHOPS. A place where you can bet whether a stock will go up or down. You do the guessing and the "bucket shop" makes the money. If you win sometimes you get your money back and sometimes you don't. "TIPSTERS." The "tipster" in Wall Street is like the tout on the race track. He pretends to know all about it, and is a very solemn and mysterious individual. He tells one man to buy and another to sell, knowing that whichever way the market goes one of them will be a winner, and the "tipster" will get his share. The one who wins tells his friends, who think the "tipster" must be a wonderfully shrewd individual, and in this way he builds up a profitable business, and the "lambs" come flocking his way. He keeps on telling one set of his victims to buy a certain stock, and another set to sell it. Whether the stock goes up or down the "tipster" wins, and those who are on the right side of this particular deal spread his name and fame among their acquaintances. "INFORMATION BUREAUS." These bureaus are "tipsters" pure and simple, only they travel under the name of a "bureau," instead of their individual names. "A SCALPER." One who is in the market continually guessing and gambling on the rise or fall. He risks a thousand dollars to gain twelve and one-half dollars. DEALING ON MARGIN.
