Day TradingA style of trading where all positions are cleared before the end of the trading day. Contrast this with position trading, where stocks or securities may be held for longer periods.
Dead CrossA signal where the shorter moving average moves below the longer moving average. Usually, this term is associated with the 50-day moving average crossing below the 200-day moving average. See ChartSchool article on Moving Averages.
DecliningA market stage of a stock that is characterized by a downtrend with subsequently lower highs and lower lows.

Detrended Price Oscillator (DPO) A price oscillator used to identify cycles in a price plot. DPO is based on the difference in price and a displaced moving average. For more, see our ChartSchool article on the Detrended Price Oscillator (DPO).
Directional Movement Indicator (DMI) An indicator that plots a positive +DI line measuring buying pressure and a negative -DI line measuring selling pressure. The DMI pattern is bullish as long as the +DI line is above the -DI line. The Average Directional Index line is derived from this system and is based on the spread between the +DI and -DI lines. For more, see our ChartSchool article on the Average Directional Index.
DistributionThe systematic selling of a security without significantly affecting the price. After an advance, a stock may start forming a top and trade sideways for an extended period. While this top forms, a security's shares may experience distribution as well-informed traders or investors seek to unload positions. A quiet distribution period is usually subtle and not enough to put downward pressure on the price. More aggressive distribution will likely put downward pressure on prices.
DivergenceA situation that occurs when two lines on a chart move in opposite directions vertically. People often look for divergences by comparing a stock's direction to the direction of its RSI, its MACD or its Stochastic Oscillator. There are two kinds of divergences: positive and negative. A positive divergence occurs when the indicator moves higher while the stock is declining. A negative divergence occurs when the indicator moves lower while the stock is rising.
DojiA candlestick with a body so small that the open and close prices are equal. A Doji occurs when the open and close for that day are the same, or very close to being the same. See ChartSchool article on Introduction to Candlesticks.

Dow Jones Industrial Average ($INDU) The Dow Jones Industrial Average ($INDU) is a price-weighted average of 30 blue chip stocks published by Dow Jones & Co. Because it is price-weighted, stocks with the highest prices will have the most influence and those with the lowest, the least influence.
Dow Jones Transportation Average ($TRAN) The Dow Jones Transportation Average ($TRAN) consists of 20 stocks in the transportation business. Originally the index only included railroads; now airlines and trucking companies are included. According to the Dow Theory, a new major high in the DJIA should be confirmed by a new major high in this index before it is considered a reliable signal.
Dow Jones Utilities Average ($UTIL) The Dow Jones Utilities Average ($UTIL) is used as a surrogate for bond prices. The DJUA is often a leading indicator of broad market trends since these stocks are interest-rate sensitive. Utility companies typically have large amounts of debt on which they pay interest and hold cash for capital improvements, so they are affected by interest rate changes sooner than other industries.
Dow TheoryOne of the oldest and most highly regarded technical theories. A Dow Theory buy signal is given when the Dow Industrial and Dow Transportation averages close above a prior rally peak. A sell signal is given when both averages close below a prior reaction low. See ChartSchool article on Dow Theory.
Down TrendlineA straight line drawn down and to the right above successive rally peaks. The longer the down trendline has been in effect and the more times it has been tested, the more significant it becomes. A violation of the down trendline usually signals a reversal of the downtrend.
