MA 50

Trend

The 50-day average: the standard reference for the medium-term trend and one of the most closely watched lines in the market.

Construction & calculation

Average of the closing prices over the past 50 trading days (about a quarter).
In the scanner's chart module the MA50 is drawn as an EMA (exponential, recent days weigh more), so the line reacts faster.
In the Golden Cross calculation the classic SMA (plain average) is used.

SMA(50) = sum of the last 50 closing prices / 50

Interpretation

Price above the MA50 = medium term is bullish; below it = the trend is broken or turning.
Because so many market participants watch this line, in practice it often acts as a support or resistance level (a self-fulfilling prophecy).
A pullback to the MA50 in an uptrend is frequently used by trend followers as an entry zone.

Watch-outs & pitfalls

Gives no signal, only context. In the scanner the MA50 is not a separate buy/sell signal in the matrix; it serves as a background line and as input for the Golden Cross.

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.
