Market Synopsis
The Spread - Diff indicator calculates the arithmetic difference between prices of 2 markets. This is primarily used to track futures spreads. Futures spread traders follow price relationships between related futures, such as S & P 500 and Dow Jones futures, as well as price relationships between different contracts in the same market, such as June T-bonds and December T-bonds. Plotting this indicator requires at least two symbols in the chart.
