About Inertia Technical Indicator Described
Inertia Technical Analysis & Inertia Signals
Developed by Donald Dorsey & was originally used to trade Stocks & Commodities market, before forex traders took it & started trading the forex market using this indicator.
Dorsey chose to name it "Inertia" because of his interpretation of the market trend. He claimed that a forex market trend is the overall result of inertia and thus it takes more momentum for a trending market to reverse its direction than to continue moving in the same direction. Therefore, a Forex trend is the measurement of market inertia. This is an oscillator that uses the scale of zero to a hundred. Signals are generated using the 50 level center line crossover method.

In physics, the term Inertia is defined in terms of mass and direction of motion. Using the standard technical analysis, the direction of motion of the trend can be easily defined. However, the mass can't be easily defined. Dorsey claimed that the volatility of a financial instrument might be the simplest and the most accurate measurement of inertia. This theory led to the use of the Relative Volatility Index (RVI) as the basis to be used as a trend technical indicator. Therefore Inertia indicator is comprised of: RVI smoothed by a linear regression.
Forex Technical Analysis & How to Generate Signals
When it comes to trading the currency market using this indicator, the signals generated are fairly simple to interpret. Below are 2 examples illustrated using forex charts showing how buy and sell signals are generated using Inertia.
Upward FX Trading Trend - Bullish Buy Forex Signal
If the Inertia is above 50, positive inertia is indicated, this therefore defines the long-term Forex trend as upward as long as the indicator remains above 50. When it crosses to levels below 50 then this is interpreted as an exit signal. The chart below shows an example of how a buy signal is generated.

Upwards Trend - Bullish Signal
Downwards FX Trading Trend - Bearish Sell Forex Signal
If the Inertia is below 50, negative inertia is indicated, this therefore defines the long-term forex trend as downwards as long as the indicator remains below 50. If it goes above 50 then this is interpreted as an exit signal. The currency chart below shows how a sell signal generated.

Downwards Trend - Bearish Signal
