(The derivative is called "<strong>velocity</strong>" in technical stock analysis). MACD estimates the derivative as if it were calculated and then filtered by the two low-pass filters in tandem, multiplied by a «gain» equal to the difference in their time constants. It also can be seen to approximate the derivative as if it were calculated and then filtered by a single low pass exponential filter (EMA) with time constant equal to the sum of time constants of the two filters, multiplied by the same gain.<sup><a href="/r.php?u=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FMACD%23cite_note-5&s=3607422374">[5]</a></sup> So, for the standard MACD filter time constants of 12 and 26 days, the MACD derivative estimate is filtered approximately by the equivalent of a low-pass EMA filter of 38 days. The time derivative estimate (per day) is the MACD value divided by 14.</p>The average series is also a derivative estimate, with an additional low-pass filter in tandem for further smoothing (and additional lag). <strong>The difference between the MACD series and the average series (the divergence series) represents a measure of the second derivative of price with respect to time («acceleration» in technical stock analysis).</strong> This estimate has the additional lag of the signal filter and an additional gain factor equal to the signal filter constant<a href="/r.php?u=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FMACD&s=602033844"><br/> </a>"
