Momentum (10)

Momentum

The absolute version of the ROC: simply the price difference from ten days ago, expressed in euros or dollars instead of percent.

Construction & calculation

Momentum = today's closing price minus the closing price of 10 trading days ago.
The scanner then smooths that line with an SMA(9) to remove the flapping around the zero line.

Momentum = C(today) - C(10 days ago) Filtered = SMA(Momentum, 9)

Interpretation

Above zero: the price is higher than ten days ago. Below zero: lower.
It is about the slope: a rising momentum above zero means acceleration, a falling momentum above zero means the trend is having a harder time.

How the signal works in this scanner

Buy signal (green)The smoothed momentum crosses zero from below to above within the last 15 bars and is still above it.

Sell signal (red)It crosses zero from above to below and stays below it.

Watch-outs & pitfalls

Because the value is in price units, the levels are not comparable between stocks. Only the zero line has meaning.
For comparison between stocks you are better off using the ROC (percentage).

Data note. The scanner works exclusively with closing prices (daily). Wherever the classic formula needs High, Low or Volume, these are approximated: the daily range via the rolling max/min of the closing price over the recent bars, and volume via the relative size of the day's move compared with the recent average. The signal logic is identical to the original, but absolute values may differ slightly from platforms that use intraday data and real volume.

Disclaimer. This explanation is educational and does not constitute investment advice. A technical signal is a probability, not a certainty: always use it together with other signals, the broader trend, the news around the stock and a predefined risk-management plan.
