Glimpse: VOLUME INDICATORS, MOMENTUM DIVERGENCE & ADVANCED TECHNICAL ANALYSIS

Indian share market learning reference for NSE and BSE. Includes definitions, practical examples, and calculation formulas where applicable.

201. OBV — On-Balance Volume

Meaning: On-Balance Volume (OBV) is a cumulative volume indicator that adds or subtracts the period's traded volume depending on whether the closing price rose or fell.

How it works: OBV is used to examine whether volume appears to support a price trend. Rising OBV can support an advancing trend; falling OBV can support a declining trend. Divergence may warn that price and volume are behaving differently.

Formula

Example: Yesterday's OBV is 1,000,000 shares. Today's volume is 120,000 and the close is higher, so today's OBV = 1,120,000. If the close were lower, OBV would be 880,000.

Caution: OBV is cumulative and its absolute value is usually less important than its direction and relationship to price. Volume data quality and timeframe matter.

202. Accumulation/Distribution Line (A/D Line)

Meaning: The A/D Line is a cumulative indicator that combines trading volume with the closing price's location within the period's high-low range.

How it works: A close near the high contributes positive money-flow volume; a close near the low contributes negative money-flow volume. The cumulative line may help assess buying or selling pressure.

Formula

Example: High ₹110, Low ₹100, Close ₹108, Volume 50,000. Multiplier = [(108−100)−(110−108)]/(110−100) = 0.6. Money Flow Volume = 0.6 × 50,000 = 30,000; add 30,000 to the previous A/D value.

Caution: The indicator does not account for price gaps between sessions in the same way as some other measures, and it can diverge from price for extended periods.

203. CMF — Chaikin Money Flow

Meaning: Chaikin Money Flow (CMF) measures money-flow volume over a chosen lookback period, commonly 20 or 21 periods.

How it works: Positive CMF means the closes have, in aggregate, tended to occur nearer the highs of their ranges; negative CMF means they have tended to occur nearer the lows. Traders often use zero-line crosses and divergence as context, not standalone signals.

Formula

Example: If the 20-period sum of money-flow volume is 2,000,000 and the 20-period sum of volume is 10,000,000, CMF = 2,000,000 / 10,000,000 = +0.20.

Caution: CMF can be distorted by gaps and may remain positive or negative while price reverses. Check the price structure and volume.

204. MFI — Money Flow Index

Meaning: The Money Flow Index is a volume-weighted momentum oscillator, often described as a volume-based relative strength indicator. A common setting is 14 periods.

How it works: MFI compares positive and negative money flow derived from typical price and volume. High readings are often interpreted as strong buying pressure and low readings as strong selling pressure, but overbought/oversold readings can persist during trends.

Formula

Example: If the positive-money-flow sum is ₹8,000,000 and negative-money-flow sum is ₹2,000,000, the ratio is 4. MFI = 100 − (100 / 5) = 80.

Caution: Vendors can differ in implementation details. An MFI above 80 or below 20 is not an automatic reversal signal.

205. Volume Oscillator

Meaning: The Volume Oscillator compares a shorter moving average of volume with a longer moving average of volume.

How it works: A positive reading means the short-term average volume is above the long-term average; a negative reading means it is below. It can help identify changes in participation.

Formula

Example: Short volume MA = 1,500,000 shares and long volume MA = 1,000,000 shares. Oscillator = [(1,500,000−1,000,000)/1,000,000] × 100 = +50%.

Caution: Settings vary by charting platform. A high reading means volume has increased relative to its baseline, not that price must rise.

206. Volume-Price Confirmation

Meaning: Volume-price confirmation is a method of checking whether trading volume supports the direction or significance of a price move.

How it works: A breakout accompanied by higher-than-usual volume may be more convincing than one on unusually low volume. Rising prices on expanding volume can indicate participation; rising prices on fading volume may warrant closer inspection. These are tendencies, not rules.

Formula

Example: A stock breaks above ₹250 resistance with 900,000 shares traded versus a 20-session average of 500,000. Relative volume = 900,000 / 500,000 = 1.8×.

Caution: Compare like with like: intraday volume changes by time of day, and corporate events or block trades can skew volume.

207. Bullish Divergence

Meaning: Bullish divergence occurs when price forms a lower low while a momentum indicator forms a higher low.

How it works: The indicator's loss of downside momentum may warn that selling pressure is weakening. Divergence is a warning condition, not proof that a bottom has formed.

Formula

Example: A stock makes swing lows at ₹200 and ₹190, while RSI makes lows of 22 and 29. Price has a lower low, but RSI has a higher low, which is a bullish divergence candidate.

Caution: Divergence can persist through a strong downtrend. Traders commonly wait for a price break, bullish candle, or support reclaim.

208. Bearish Divergence

Meaning: Bearish divergence occurs when price forms a higher high while a momentum indicator forms a lower high.

How it works: It can indicate that upside momentum is weakening even as price advances. It is a potential warning, not a guaranteed sell signal.

Formula

Example: A stock reaches ₹300 and later ₹310, while RSI peaks at 76 and then 68. The higher price high with a lower RSI high is a bearish divergence candidate.

Caution: Strong trends can continue despite divergence. Seek price-action confirmation and plan risk.

209. Hidden Bullish Divergence

Meaning: Hidden bullish divergence is commonly identified when price makes a higher low while a momentum indicator makes a lower low.

How it works: In a broader uptrend, it is often interpreted as a possible continuation signal after a pullback, rather than a major reversal signal.

Formula

Example: A stock rises from ₹200 to ₹240, pulls back to ₹220, and later pulls back only to ₹225. If RSI's corresponding lows fall from 42 to 35, the higher price low plus lower RSI low fits a hidden bullish divergence candidate.

Caution: Indicator settings and swing selection affect identification. Confirm that the wider trend is actually upward.

210. Hidden Bearish Divergence

Meaning: Hidden bearish divergence is commonly identified when price makes a lower high while a momentum indicator makes a higher high.

How it works: In a broader downtrend, it is often interpreted as a possible continuation signal after a rally.

Formula

Example: A stock falls from ₹300 to ₹250, rebounds to ₹275, and then rebounds only to ₹268. If RSI highs rise from 55 to 61, this can fit hidden bearish divergence.

Caution: This pattern is not standardized across all trading systems. Use trend context and price confirmation.

211. Momentum

Meaning: Momentum describes the speed or strength of a price move over time. It can refer to a general market characteristic or to a specific indicator.

How it works: Positive or increasing momentum suggests prices are advancing more strongly relative to the chosen lookback; negative or weakening momentum suggests the opposite. Different indicators measure momentum differently.

Formula

Example: Today's close is ₹520 and the close 10 sessions ago was ₹500. Ten-period momentum = ₹520 − ₹500 = +₹20.

Caution: The absolute difference depends on the stock's price scale. Percentage-based measures can be more comparable across securities.

212. Momentum Oscillator

Meaning: A momentum oscillator converts price momentum into a numerical series, often with a reference line or bounded scale. RSI and Stochastic are examples of oscillators, though their formulas differ.

How it works: Traders examine the oscillator's direction, extremes, crossovers, and divergence. Interpretations depend on the indicator and market regime.

Formula

Example: Close now is ₹440 and 10 periods ago it was ₹400. Simple momentum = ₹40; percentage ROC = (40 / 400) × 100 = 10%.

Caution: Do not apply RSI thresholds or other indicator rules to a different oscillator without checking its definition.

213. ROC — Rate of Change

Meaning: Rate of Change (ROC) expresses the percentage change in closing price over a selected lookback period.

How it works: Positive ROC means the current close is above the close N periods ago; negative ROC means it is below. A rising ROC indicates the rate of price change is increasing under this calculation.

Formula

Example: Today's close is ₹660 and the close 10 sessions ago was ₹600. ROC = [(660−600)/600] × 100 = +10%.

Caution: ROC is sensitive to the chosen lookback and base price. A positive ROC does not by itself imply the stock is a good buy.

214. Price Momentum Strategy

Meaning: A price momentum strategy seeks securities whose prices have been rising or falling strongly over a defined period, based on the strategy's rules.

How it works: A system may rank stocks by past returns, apply trend or liquidity filters, and rebalance periodically. Momentum can persist, but sharp reversals and crowding can create losses.

Formula

Example: Stock A rose from ₹400 to ₹460 over 3 months: return = [(460/400)−1]×100 = 15%. Stock B rose 8% over the same period. A simple momentum screen ranks A above B before costs and risk checks.

Caution: Past performance does not guarantee future returns. Include costs, slippage, survivorship bias, drawdowns, and out-of-sample testing in backtests.

215. Relative Strength

Meaning: Relative strength compares a stock's performance with a benchmark or another stock. It is distinct from the RSI indicator.

How it works: If a stock outperforms the Nifty 50 over the same period, it may be showing relative strength. Some methods use a ratio chart; others compare percentage returns.

Formula

Example: A stock returns 12% over a month while the Nifty 50 returns 7%. Relative return difference = 12% − 7% = +5 percentage points.

Caution: A stock can outperform a falling benchmark while still declining in absolute terms. Specify whether you mean a price ratio, relative return, or RSI.

216. Relative Weakness

Meaning: Relative weakness means a stock is underperforming its benchmark or comparison group over the selected period.

How it works: Weak relative performance can help traders avoid lagging shares or identify candidates for further bearish research. It does not prove that a stock will keep underperforming.

Formula

Example: A stock falls 6% while the Nifty 50 falls 2%. Relative return difference = −6% − (−2%) = −4 percentage points, indicating underperformance.

Caution: Compare the same dates and adjust for corporate actions where necessary. Different sectors can have different benchmark sensitivities.

217. Indicator Confluence

Meaning: Indicator confluence is the agreement of multiple independent forms of evidence, such as trend, momentum, volume, and support/resistance.

How it works: A trader might look for price above a rising moving average, a bullish momentum reading, and a breakout supported by volume. The goal is to reduce reliance on one signal, not to create certainty.

Formula

Example: Trend = +1, momentum = +1, volume confirmation = +1, so the illustrative score is +3. A trader still checks price levels, liquidity, and risk before any decision.

Caution: Indicators may be correlated and count the same underlying price information more than once. More indicators do not automatically mean better decisions.

218. MTF — Multi-Timeframe Analysis

Meaning: Multi-timeframe analysis evaluates the same instrument across more than one chart interval, such as daily, 1-hour, and 5-minute charts.

How it works: A trader may use a higher timeframe to identify the broader trend, an intermediate timeframe to find structure, and a lower timeframe to refine timing. The timeframes should suit the holding period.

Formula

Example: A swing trader sees the daily close above a rising 50-day EMA, then waits for a 1-hour pullback and a 15-minute recovery signal. The example describes a process, not a recommendation.

Caution: Signals can conflict across timeframes. Avoid using unfinished higher-timeframe candles as if their final values were known.

219. Trend Confirmation

Meaning: Trend confirmation is the process of checking whether price action and supporting evidence agree with a proposed trend direction.

How it works: Possible checks include higher highs and higher lows, a moving-average slope, a breakout holding above resistance, and supportive volume. No single confirmation method is universally correct.

Formula

Example: A stock forms a higher high and higher low, closes above its 50-day EMA, and holds a prior resistance level on a retest. These observations support—but do not guarantee—an uptrend interpretation.

Caution: Trend confirmation is often delayed by design. A later entry may reduce false signals but can worsen the entry price.

220. Trend Strength

Meaning: Trend strength describes how persistently or forcefully price moves in a direction, as distinct from trend direction itself.

How it works: Some traders use the ADX indicator, while others examine swing structure, slope, volatility, and pullback depth. ADX measures trend strength, not whether the trend is bullish or bearish.

Formula

Example: If +DI = 30 and −DI = 10, DX = 100 × |30−10|/(30+10) = 50. ADX then smooths DX over time; DX = 50 is not the same as ADX = 50.

Caution: Common ADX guideposts such as 20 or 25 are heuristics, not universal cutoffs. A high ADX can accompany a strong downtrend as well as a strong uptrend.

Formula and Trading Notes

These are commonly used textbook formulas; charting platforms can differ in lookback periods, smoothing methods, initialization, and handling of missing data.

Use consistent adjusted price and volume data when comparing historical performance, especially around splits, bonuses, and other corporate actions.

Formulas explain calculations; they do not independently create profitable trading signals. Test any rule on appropriate historical data and include brokerage, taxes, slippage, liquidity, and risk controls.
