_Program 83, designed for TradeStation RadarScreen and Scanner, looks for regular bullish and bearish divergences between a price and each of sixteen oscillators (see the names of the oscillators below). The number of oscillators for which there is bullish divergence for each bar is summed. The number of oscillators for which there is bearish divergence is also summed and the two sums are plotted in Radarscreen and available within TradeStation Scanner.
[highlight4]Some technical analysts believe that bullish and bearish divergences in an oscillator may foreshadow price reversals.[/highlight4]
When _Program83 is used in Radarscreen, if the number of bullish divergences exceeds the user input: BullThreshold then the background color of the bullish count plot is turned green. If the number of bearish divergences exceeds the user input: BearThreshold then the background color of the bearish count plot is changed to red. If Alerts are enabled the program also generates alerts when the thresholds are exceeded.
The companion program, _Program83-tester (based on program 62) was created to help test and verify whether _Program 83 was functioning as expected during the development process. This additional program (included in the download) is not necessary to run _Program 83 but it does provide additional useful functionality. For example, _Program83-tester will indicate if a divergence with a specific oscillator has occurred. It can also be used to give a visual indication of a divergence on a chart for a specific oscillator. In Radarscreen it plots whether there is bullish and/or bearish divergence between price and an individual oscillator selected by the user.
Video demonstration of program 83
On a chart _Program83-tester plots the oscillator selected by the user in a subgraph. When a potential divergence is found a line is drawn between price pivots corresponding to pivots in the oscillator.
Since price and the oscillator pivots do not necessarily occur on exactly the same bar, the program has a user input (BarTol) to determine how many bars apart the price pivot and the stochastic pivot can occur to still be considered a price/oscillator pivot pair. The price pivot can occur before the oscillator pivot, or vice versa.
Also used in the testing process and included within _Program83, but commented out, are additional plot statements that show whether there is divergence for each of the 16 oscillators. I demonstrate the test program in the video below.
The program, written for TradeStation 9.5 and works with 10.0. and higher. In Radarscreen _Program83 can be used with tick, second, minute, daily, weekly and monthly bars. With the Scanner it can also be used with volume bars. The amount of processing resources required increases with the number of symbols and the smaller the bar length. This program does not work with MultiCharts.

The word before the input name is the data type as follows:
- int = integer (i.e. 0, 1, 2, 3 )
- bool = boolean (i.e. true or false)
- double = double(i.e. 2.34236)
- string = string (i.e. “words”)
After the input names is a brief explanation of its use. The ‘//’ tells the program that the words are comments and they do not affect the running of the program.
The number contained within parentheses is the default value for the user input. This means that the program will run with this value unless you change it.

Summary of the oscillators
Relative strength index (RSI)
The relative strength index (RSI) was developed by J. Welles Wilder and is a momentum oscillator that measures the speed and change of price movements. It oscillates between zero and 100.
Moving average convergence divergence (MACD)
The moving average convergence divergence (MACD) returns the difference between a fast and slow exponential moving average based on the same price.
The stochastic oscillator is a momentum indicator that shows the location of the close relative to the high-low range over a set number of periods. It follows the momentum of price.
True strength index (TSI)
The true strength index (TSI) is a momentum-based indicator, originally developed by William Blau. It is used to find the trend and overbought/oversold conditions.
Commodity channel index (CCI)
The commodity channel index (CCI) is an oscillator introduced by Donald Lambert in 1980. It is calculated as the difference between the typical price of a commodity and its simple moving average, divided by the mean absolute deviation of the typical price. In TradeStation the index is scaled by an inverse factor of 0.015.
Stochastic of RSI
The stochastic of the RSI is calculated using the following formula:
TrueStrengthIndex = 100 * _Divide( XAverage( XAverage( Price – Price, TSIPeriod1 ), TSIPeriod2 ), XAverage( XAverage( AbsValue( Price – Price ), TSIPeriod1 ), TSIPeriod2 ) );
XAvgTSI = XAverage( TrueStrengthIndex, TSIPeriod3 );
_Divide is a function that divides the first input by the second, while checking for divide by zero errors.
