Momentum Indicator

Price units versus percentages Raw MOM uses the price’s own units. Percentage rate of change is (current − earlier) ÷ earlier × 100. From $100 to $110, raw MOM is +$10 and ROC is +10%. Dollar momentum alone is not a scale-neutral comparison between differently priced stocks. Source 2.

Check the platform’s convention MetaTrader’s Momentum uses current ÷ earlier × 100, so equal prices give 100, not zero. For the same $100 to $110 example, the ratio is 110. This is a different display convention, not a disagreement in the underlying prices. Source 3.

Above zero Positive and rising: the raw price difference is positive and growing. Positive and falling: the difference is still positive but smaller. Neither statement establishes whether a position is suitable or whether the next close will rise.

Below zero Negative and falling: the raw difference is becoming more negative. Negative and rising: the difference is less negative. A recovery toward zero can fail. Crossing zero is a chart observation, not a guaranteed entry, exit or loss limit.

Keep settings comparable A shorter lookback changes the comparison interval; a longer one uses a more distant close. Results can differ in sign. Write down the settings before comparing charts. There is no universally best period established by this lesson.

Avoid claiming physical speed Traders may call a strengthening price difference acceleration and a shrinking one deceleration. The indicator is a rolling difference, not a direct measure of buying orders or a precise physical acceleration. Check the actual prices rather than inferring a cause from the line alone.

The opposite comparison Bullish divergence compares a lower price low with a higher momentum low. It may prompt a closer look at the chart, but declining prices can continue. Avoid labeling every small mismatch as a turning point.

A rule needs an evaluation If studying a crossover or divergence rule, define it before checking outcomes. Include failed signals, a separate evaluation period and realistic costs. A hand-picked successful chart cannot establish how often a rule works. This page does not claim a tested edge.

Related views are not independent proof RSI, MACD, Stochastics and raw MOM transform price history in different ways. Two tools built from the same closes do not become two independent facts simply because both point upward. Support, resistance and volume also require a clear method and context.

Describe the whole decision Record the evidence, time horizon, liquidity and possible loss before considering an action. A chart line cannot guarantee an execution price or protect an account from losses. Technical analysis should not be the sole basis for research. Source 4.

Before interpretation Confirm the formula and reference line. Record the exact closes and lookback. Separate positive or negative from rising or falling. Check the underlying price path and note whether you selected swing points after seeing the outcome.

Before any decision State what evidence would weaken the interpretation, what uncertainty remains and why a chart signal is not sufficient by itself. Local reading markers and these three checks are learning aids; they do not complete an LMS lesson.
