#### Topic: Indicator Calculations

Hi guys,
I need help understanding the logic behind the calcs for Osc of Momentum. Please, correct me if I am wrong. What this indicator does is calculate two momentum and substract the second from the first(as in the last for loop). Am I understanding the code correctly? Because I must be missing something, If I insert the two momentum in the chart, there is no way I can get the Oscillator value by just substractin one from the other. Are there other separated class for oscillators that is in other place?

// Calculation
int iFirstBar = iPeriod1 + iPeriod2 + 2;
