Momentum (MTM)

What is it?

Momentum (MTM) is a simple leading momentum indicator that is similar to the Rate of Change (RoC). Like the RoC, the Momentum (MTM) oscillator measures the pace at which a trend is accelerating or decelerating. It does this by comparing the latest price close to a price close of a specified period in the past. Thus, a 7-day MTM indicator compares the latest price close to the price close of seven days ago. Like the RoC, the MTM indicator is very sensitive to price changes and tends to be erratic.

How is it calculated?

Momentum (MTM) is simply calculated by subtracting the previous price close from the latest price close using the formula:
Momentum = Latest close - Specified close
where the specified period is any previous price close specified by the trader. The result is plotted as an unbound oscillator that oscillates above and below a center line, namely the zero line.

How is it used?

The key consideration when using MTM is the center line. When the price of the underlying security is in an uptrend, a buy signal is generated when the Momentum oscillator moves below the center line and starts to move back up. When the price of the underlying security is in a downtrend, a sell signal is generated when the Momentum oscillator moves above the center line and starts to turn back down.

Entry signals are also generated when a trend line drawn on the Momentum oscillator is violated.

Wealth Warning

Trading equities, options, derivatives, currencies, commodities or any other financial security can offer significant returns BUT can also result in significant losses if the market moves against your position. It requires a strong commitment to skill development, knowledge acquisition, and emotional control. It should be treated as a business with a clear business plan, a risk analysis, and set of attainable goals. The risk associated with trading the vagaries of the stock markets is probably the most important consideration as it has a profound effect on emotional control. You should not trade the stock markets with money you cannot afford to lose as there is considerable exposure to risk in any stock market transaction.

Furthermore, the past success of any trading method, strategy, or system is only indicative of future success. Under no circumstances should past success be construed as a guarantee of future success!


Momentum Indicators

A Momentum Indicator

Momentum indicators can be used to track the rate at which the price of the underlying security changes rather than the price changes itself. These indicators are usually leading indicators as they tend to be oscillators by nature.

Some momentum indicators, such as the Stochastic Oscillator and the Relative Strength Index (RSI), have an upper boundary (usually 100) and a lower boundary (usually -100) while others, such as the Commodity Channel Index and the MACD, do not have upper and lower boundaries. In the case of the latter, historical high and low levels ...

RoC

The Rate of Change (RoC) indicator is a leading momentum indicator that measures the strength of a trend by determining whether the trend is accelerating or decelerating. It does this by comparing the most recent price close to a price close of a specified number of bars ago. Thus, a 7-day RoC compares the latest price close to the price close of seven bars ago. However, the RoC tends to be very sensitive to price changes and can be quite erratic.

A refinement of the RoC, called the Smoothed Rate of Change (S-RoC) compares two EMAs ...
