I don’t understand what an Market is and how it is different from a regular index?

Regular indices like the Dow Jones, ticker symbol INDU are available from many sources. These sources provide the open high low and close for the index itself. No volume figures are available for most indices. A Market is a unique ticker available only in TradingExpert Pro Software. Instead of analyzing the price action of an index on it’s own, TradingExpert Pro combines an index price ticker like DJI with the breadth information (advancing, declining issues and volume) from an associated exchange. For example the TradingExpert Pro unique ticker DJIA is a market that combines the DJI index with the breath data from the New York Exchange. When you chart the ticker DJIA, you will see a price chart of DJI, with technical indicators that are also volume based – derived from the New York Exchange breadth data.
