Moving average crossover of a 15-day exponential close-price MA (red) crossing over a 50-day exponential close-price MA (yellow) In the statistics of time series, and in particular the stock market technical analysis, a moving-average crossover occurs when, on plotting two moving averages each based on different degrees of smoothing, the traces of these moving averages cross.
When McClellan Oscillator crosses below zero line it tells us that "19-day EMA of advances minus declines" crossed below "39-day EMA of advances minus declines" which indicates that an increase in the number of declining stocks on the NYSE Exchange is strong enough to consider it as a signal of a possible down-move on the NYSE index.

Moving average envelope is a technical analysis indicator, showing lines above and below a moving average. [1]The starting point is a simple or exponential N-period moving average which is calculated as the average of the stock price for each of the previous N periods (usually days).
The relationship between different moving average trading rules is explained in the paper "Anatomy of Market Timing with Moving Averages". [4] Specifically, in this paper the author demonstrates that every trading rule can be presented as a weighted average of the momentum rules computed using different averaging periods.
The Double Exponential Moving Average (DEMA) indicator was introduced in January 1994 by Patrick G. Mulloy, in an article in the "Technical Analysis of Stocks & Commodities" magazine: "Smoothing Data with Faster Moving Averages" [1] [2] It attempts to remove the inherent lag associated with Moving Averages by placing more weight on recent values.
Note that the distribution's mode will lie with p N-2 's weight, i.e. in the graph above p 8 carries the highest weighting. An N of 1 is invalid. The easiest way to calculate the triple EMA based on successive values is just to apply the EMA three times, creating single-, then double-, then triple-smoothed series. The triple EMA can also be expressed directly in terms of the prices as below ...
An exponential moving average (EMA), also known as an exponentially weighted moving average (EWMA), [5] is a first-order infinite impulse response filter that applies weighting factors which decrease exponentially. The weighting for each older datum decreases exponentially, never reaching zero. This formulation is according to Hunter (1986). [6]
Since either a reversal or a trading range follow a valid trendline violation, it's evident that upside momentum has temporarily dissipated, causing the KST to cross below its moving average. Traditionally, the MACD gives buy and sell signals when it crosses above and below its exponential moving average, known as the “signal line”.
