MACD

The moving average convergence divergence indicator: the difference between a fast and a slow exponential moving average of price.

Formula MACD Line = 12-period EMA - 26-period EMA; Signal Line = 9-period EMA of the MACD Line
Unit

In depth

MACD measures the gap between two averages, so it is positive when the shorter average is above the longer and rises when that gap widens — it describes the rate at which price is separating from its own trend. It is unbounded, unlike an oscillator, so its readings are not comparable across securities or across price levels: a MACD of 3 means something different on a ₹60 stock and a ₹3,000 one. Users typically watch three things: the zero-line crossing, the signal-line crossing, and divergence against price. All three are descriptions of a smoothed series, and none is a forecast.

Worked example

A 12-period EMA of ₹506 and a 26-period EMA of ₹496 give a MACD of ₹10. On a ₹60 stock the same ₹10 gap would be impossible — the reading scales with price, which is why cross-stock comparison is meaningless.

Illustrative figures, chosen so the arithmetic is easy to follow. Not a live price and not a valuation of any company.

This entry explains what “MACD” means. It is not investment advice and not a recommendation to buy or sell any security. Any numbers above are illustrative, not live prices, and nothing here predicts price direction or rates a stock.
