Same TA, different values for different software

    Just curious whether each charting software calculates TA differently? For example, I'm using CCI indicator with same period and source (OHLC average) on Sierra Chart and QT. Under most circumstances, values are close, but sometimes (like today), values are way off.

    Is there a particular reason for this?
