I want to clear up a few points

[USER=84784]@Wilham[/USER] raised a valid point & asked about additional information from [USER=33203]@MovingAverage[/USER] to which trend indicator he uses.


Interest turned to the (TSI) indicator 

Simply put, the (TSI) is a double smooth momentum oscillator of changing prices. The (TSI) captures these fluctuations & then applies smoothing. Pretty simple really.


Let me explain the (TSI) in English

The (TSI) is a calculation of the price change from one period to the next. It is accomplished by calculating a 25-period (EMA) of this price change. (the first step of the process)


Here is the twist for double smoothing 

Then the results of the first step - calculate the 13-period (EMA) of this 25-period (EMA).  Wham, bam, thank you, mam - we have just created double smoothing.


The Signal Line

[USER=17857]@qldfrog[/USER] was curious about the signal line. The signal line is simply an exponential moving average of TSI. [USER=33203]@MovingAverage[/USER] made the reference to the (MACD) signal line as a mental comparison & the comparison stops there.


The Buy Signal

In my previous post, I used a simple "Signal line crossover" to demonstrate the simplicity of getting into an uptrend. Using the zero-line cross is the simplest way to generate a signal. (posted previously)


For the more advanced

The first part, which is the double smoothed price change, sets the (+/-) representation of the TSI. The indicator is negative when the double smoothed price change drops below the (zero-line) & positive when it's above the (zero-line). The double smoothed absolute price change normalizes the indicator & limits the range of the (TSI) oscillator.


In other words

The TSI indicator measures the double smoothed price change relative to the double smoothed absolute price change. A string of large positive price changes results in relatively high positive readings, signalling strong upside momentum. A string of large negative price changes pushes the TSI into negative territory.


The (TSI) is an oscillator that fluctuates between positive & negative in relation to the zero-line

As with many momentum oscillators, the centreline defines the overall bias. Positive momentum when TSI is above the (zero-line) & negative momentum when it's below.


If this has sparked an interest

You can find more about momentum indicators by doing a "search by [USER=57364]@Skate[/USER]" - I'm sure I've made dozens of posts on the subject.
