Nicolas Darvas, author of the phenomenal best-seller, How I Made $2, 000, 000 In The Stock Market, has devised a breakthrough system for charting the stock market. Called the DAR-CARD, it is easy to use end has the all-important ingredient that existing systems lack: DAR-CARD needs no interpretation. The philosopher’s stone of the stock market, DAR-CARD converts data into profits. It eliminates confusing fluctuations and indicates the trend and the buy and sell points-the factors that matter if you want to make money. DAR-CARD is a compact, visual representation of Nicolas Darvas’s system; a simple device to be carried in the pocket, to be checked against each day’s closing prices. No bigger than a postcard, DAR-CARD contains its own built-in instructions and all the information necessary to make a decision on whether to buy, sell or hold. In addition to providing this unique tool for dealing with the stock market, Darvas offers straightforward advice on: when to buy; what shall I watch for; five ways to create favorable odds; how to detect a must sale; how long to hold a stock; pitfalls of switching; what to look for before taking action.
