The Directional Trend Index (DTI) was developed by William Blau and published in his book "Momentum, Direction and Divergence".
To determine the value of the DTI William Blau first calculates a composite momentum from both highs and lows of the last days. In a next step both the composite momentum and the absolute values of the composite momentum are smoothed. The smoothed momentum is then divided by the smoothed absolute momentum and the result is multiplied with 100.
Momentum smoothing: William Blau smoothed both momentum and absolute momentum by applying an EMA several times (double or triple smoothing). This indicator allows to use 16 different moving averages for the smoothing. The same moving average type is used for all three average calculations.
Parameters: The lookback period for the momentum the number of bars from which the momentum is calculated. Blau uses a lookback period, which is different from the standard momentum. To obtain a 1-period momentum (price change from the last to the current bar) the Directional Trend Index requires a setting of 2 for the lookback period (default setting).
Signal line: William Blau did not use a signal line for the double smoothed indicators. I have added the signal line, because the cross of the signal line can be used as a trend indication. Moving average type and period for the signal line can be selected.
Histogram: The indicator has an option to plot a histogram, which shows the difference between DTI and signal line.
Trend definition: The indicator exposes the current trend via an IntSeries. The trend can be determined based on the DTI (rising & not oversold, falling & not overbought, neutral), the signal line (rising & not oversold, falling & not overbought, neutral)) or the DTI / signal line crosses. All trend definitions are not straightforward, but require a higher close to switch to an uptrend, or a lower close to switch to a downtrend. Moreover the DTI / signal line cross will only show an uptrend, when not oversold and a downtrend when not overbought.
Paint bars: The paintbars can be used to plot the trend information. The trend states are uptrend, downtrend and neutral trend as explained above. It is possible to apply the indicator to the price panel and unselect the indicator plots. This allows to use the indicator as a "paintbar only" indicator.
Sound alerts: The indicator comes with sound alerts which are triggered when the trend changes. The sound files are included with the zip file and should be manually copied into the directory Documents -> program files (x86) -> NinajTrader 7 -> sounds.
Update March 17, 2014: Option added to select sound files
The Double Smoothed Stochastics by Walter Bressert came after William Blau presented his version of the Double Smoothed Stochastics in 1991. Both indicators are widespread in the trading community, but they use different algorithms. While William Blau applied separate smoothing to numerator and denominator, Walter Bressert simply applied the Stochastics %K line to itself. Applying the Stochastics twice leads to an acceleration of the running pattern. Furthermore the Double Stochastics is smoother when compared to the classic Stochastics and generates signals more frequently.
The Double Stochastics by Walter Bressert ships with NinjaTrader as in-built indicator. This version of the Stochastics adresses a few issues of the NinjaTrader default indicator:
- The default indicator has preset the %K line smoothing to 3, value which cannot be changed.
- The default indicator does not have a signal line.
- The default indicator can only be applied to price, but cannot be applied to other indicators.
This version allows for setting the smoothing period for the %K line, comes with a signal line and maybe applied to other indicators as input series.
In this pack there are three indicators:
- Elder's Ray: composed by BullPower line and BearPower line;
- BullPower only, histogram version
- BearPower only, histogram version
This is an oscillator created by Alexander Elder and explained in his famous book "Trading For a Living". The oscillator formula is simple but useful at the same time:
- BullPower = CurrentHigh - EMA(13, Close)
- BearPower = CurrentLow - EMA(13, Close)
Chande Momentum Oscillator. This should return the same values as the standard supplied version; its advantage being ~4-6K less memory consumption. It does not iterate (neither does the supplied) so is reasonable to use with CalculateOnBarClose == false. Version 1.0.
This is a quick implementation of the Klinger Volume Oscillator as published by Stephen J.Klinger in the December 1997 issue of Technical Analysis of Stocks & Commodities. Here is a short recapitulation of how he trades the oscillator.
"The most powerful use of the KVO comes when the indicator reaches an extreme reading either above or below the center line and reverses direction. This signals an exhaustion of the prevailing trend and warns of an impending reversal in price.
The most reliable signals occur in the direction of the prevailing trend. Trades against the trend tend to be high-risk ventures.
The most important signal occurs when the KVO diverges from price action, especially on price extremes, either in
overbought or oversold territory. When a security makes a new high or low for a cycle and the KVO fails to confirm
this, the indicator is warning that the trend is losing momentum and nearing completion."
Got my hands on ToS again, and we're back in business.. - here's a come-back gift...
This is my own ToS port of SVAPO (Short-Term Volume and Price Oscillator), a trading system introduced by Sylvain Vervoort that combines both volume and price trends to identify tradable setups - full details on the concept, and trade rules that he suggests are herehttps://stocata.org/ta_en/proprietary.html
took the concept and re-wrote it for ToS, using my own preferred techniques for smoothing and averaging - to achieve less lag and make the final plot more "friendly and usable" - while maintaining the overall original concept. (let me know if interested in exact details of the differences). also changed the resulting oscillator to a restricted range -100/+100 - no longer need to use the StdDev upper/lower lines..
the code is commented - the full details of how the original SVAPO can be used for signal generation are on web site above.
I also added the option to view the resulting plot in a Stepped mode or with an Inverse Fisher Transform - we still get almost no lag as we don't use unnecessary smoothing here. you can see how the signal (in this case crossing the zero line) is in line with the K_TraderRibbon on top, sometimes ahead of it.
suggestions for use:
use K_SVAPO along with a long-term trend indicator. if you set K_SVAPO correctly, it will provide unambigious signals on ideal entry points when the price retraces before continuing the trend.
you can also use 2 K_SVAPO, one longer and one shorter to provide a similar combo. in that case, i suggest you change one of them to the "Stepper" for easier viewing
as usual, appreciate if you keep in the forum. all feedback & comments welcome, as i'm still testing this anyways,
January 18th, 2017 04:22 PM ronturner I think that this is also called the caos awesome oscillator. Some use this to identify wave 3 (strongest, ie highest o
r lowest crest) to identify wave 3. The next crest would show divergence (weaker) for wave 5 or the end of that impulse
ive wave.
January 27th, 2016 04:01 PM Trailer Guy Wow, this really works well on my 20,000 tick es chart. I don't understand the point of the color changes but that is O
K. If you want to see how someone uses this for counting go to studyofcyclesblogspot and see how the "Elliot Trader" co
unts. I just like the way it says "this move is over".
September 4th, 2013 01:47 AM poodman looks like the Awesome Oscillator, maybe it will be easier to install and use
July 15th, 2013 03:32 PM teamtc247 Awesome indicator for convergence/divergence.
