AccumDistr is the classical Accumulation/Distribution indicator.

Use :

The accumulation/distribution of price is calculate that way :

The indicator balances volumes using the closing price reported at the extreme points of the trading day.

It must confirm the stock trend in progress by moving in the same direction as the stock trend. A divergence between prices and Accumulation/Distribution is often a signal that the current trend may reverse. (more…)

Returns the Adaptive Moving Average (AMA) indicator.

Syntax:

Where:

• MAperiod: calculation period of the Adaptive Moving Average (default period is 9)
• fastSC: fast moving constants period used by the adaptive function
• slowSC: slow moving constants period used by the adaptive function
• price: applied price

Technical indicator Average Directionnal Index, usually known as ADX.

Calculation:

We first calculate +DM and -DM (the directional movement) , the number of points obtained in a direction. We apply a wilder moving average on +DM and -DM to calculate +DI and -DI. Then we calculate DX.

Dx = 100 x ((+DI) – (-DI)) / ((+DI) + (-DI)).

Finally to obtain ADX we apply again a wilder moving average on DX.

Indicator Average Directional Index Rate, also known as “ADXR”. Compute with N periods :

ADXR formula : ADXR = (ADX + ADX[n]) / 2

Calculation of ADX :

We first calculate +DM and -DM (the directional movement) , the number of points obtained in a direction. We apply a wilder moving average on +DM and -DM to calculate +DI and -DI. Then we calculate DX.

Dx = 100 x ((+DI) – (-DI)) / ((+DI) + (-DI)).

Finally to obtain ADX we apply again a wilder moving average on DX.

Call of technical indicator Aroon for its Down value over N periods.

Syntax:

Calculation:

The indicator is composed of 2 lines, Aroon Up and Down that represent the number of days since the most recent x-period high for Aroon Up and x-period low for Aroon Down.

For example, if a stock market makes a new x-day high, the Aroon Up = 100; On the other hand, if a stock has not made a new high for x days, the Aroon Up = 0.

Call of technical indicator Aroon for its Up value over N periods.

Syntax:

Calculation:

The indicator is composed of 2 lines, Aroon Up and Down that represent the number of days since the most recent x-period high for Aroon Up and x-period low for Aroon Down.

For example, if a stock market makes a new x-day high, the Aroon Up = 100; On the other hand, if a stock has not made a new high for x days, the Aroon Up = 0.

Simple Moving Average (MA) of N periods.

Syntax:

Average instruction can be extend with a second parameter under brackets to modify the arithmetic calculation of the average :

Where M can be set with any of these values, to return the specific moving average calculation:

0 = SMA

1 = EMA

2 = WMA

3 = Wilder

4 = Triangular

5 = End point

6 = Time series

7 = Hull (PRT v11 only)

8 = ZeroLag  (PRT v11 only)
