The indicator values are calculated by this formula :

• For first period (red color) = (Close - LowValue) / (HighValue - LowValue)
  

The value is between 0 - 1.
The higher value means uptrend, the lowest value means downtrend, value in the middle means sideway.

• For second period (blue color) = (Close - LowValue)*-1 / (HighValue - LowValue)

The value is between -1 - 0.
The higher value means downtrend, the lowest value means uptrend, value in the middle means sideway.

where :

• HighValue - the highest high for n period;
• LowValue - the lowest low for n period;

Input parameters:

• InpPeriod1 - First period for calculating trend;
  
• InpPeriod2 - Second period for calculating trend;
