Smoothed differential indicator by Sultonov. Indicator lines show the averaged accumulated sums of bulls and bears power for the user-defined period.

Calculation method

Bulls power is calculated by the following formula:

BullsPower(i) = SUM(Close(i) - Close(i + 1), N) / BUN

where:

• BullsPower(i) - current bulls power.
• Close(i) - Close price of the current bar.
• Close(i + 1) - Close price of the previous bar.
• N - indicator calculation period.
• BUN - number of positive increments of Close prices over N bars. The sum includes only positive increments.

Accordingly, the following formula is used for calculating the bears power:

BearsPower(i) = SUM(Close(i + 1) - Close(i), N) / BEN

where:

• BearsPower(i) - current bears power.
• BEN - number of negative increments of Close prices over N bars. The sum includes only negative increments.

The final indicator features additional smoothing of obtained lines.

Interpretation

The indicator consists of two lines filling space between them in color corresponding the trend direction. The higher line shows the stronger side. The intersection of lines (color change) indicates trend change and is a good moment for opening a deal in the direction of the power that appeared to be above the other one.

The indicator uses the classes of the SmoothAlgorithms.mqh library. Working with that class was described in details in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".

The original indicator was developed in the MQL4 language and published in CodeBase on 22.09.2017.
