Moving Average
A line that averages price over a rolling lookback window in order to smooth noise and reveal underlying direction.
What Moving Average means
A moving average is a line that averages price over a rolling lookback window, recalculated as each new period completes, so it smooths short-term noise and makes the underlying direction easier to read. The two most common forms are the simple moving average, which weights every period in the window equally, and the exponential moving average, which weights recent data more heavily. Weighted, smoothed and Hull variants exist as further refinements. The input is usually the closing price, though typical price or median price are sometimes used.
Moving averages are used in three main ways: as a directional filter, where traders take only long signals while price holds above a rising average; as dynamic support and resistance for pullback entries; and as a crossover signal, where a faster average crossing a slower one marks a change in short-term momentum. The unavoidable limitation is lag. Because the value depends entirely on data already in the window, a moving average turns after price does, and in sideways markets crossovers generate persistent whipsaw losses.
Worked example
A trader applies the 50 and 200 period simple moving averages to the EUR/USD daily chart; with the 50 at 1.0790 above the 200 at 1.0705 and price at 1.0850, the filter permits long setups only.

Trade with a regulated broker
Understanding the terminology is the cheap part. The expensive part is choosing a counterparty whose execution, financing and withdrawal behaviour match what the marketing implies. Every broker below has been reviewed with a funded live account, and each review states which legal entity and which regulator applies to the account you would actually open.
