Intraday Intensity Index
What Is the Intraday Intensity Index?
The Intraday Intensity Index is a volume-based technical indicator that tracks the flow of funds for a security by analyzing the position of the close relative to the high and low.
The Intraday Intensity Index is a technical indicator designed to approximate the volume of trading that can be attributed to institutional buying or selling. It assumes that institutional traders, who move the market, tend to execute trades that push the closing price closer to the day's high (accumulation) or low (distribution). By combining price action with volume, the index provides a more complete picture of market sentiment than price alone. It helps traders distinguish between strong trends supported by volume and weak trends that may be running out of steam. The index is often accumulated over a period (e.g., 21 days) to create the Intraday Intensity Percent, which is smoother and easier to interpret.
Key Takeaways
- Developed by David Bostian to track institutional accumulation and distribution.
- Measures whether volume is flowing into (buying) or out of (selling) a stock.
- A rising index suggests accumulation (bullish), while a falling index suggests distribution (bearish).
- Often used to confirm price trends or identify divergences.
- Similar to the Chaikin Money Flow but focuses specifically on intraday price positioning.
Calculation Formula
Intraday Intensity = [ (2 * Close - High - Low) / (High - Low) ] * Volume
How It Works
The formula calculates a value based on where the close falls within the day's range. * **Close near High:** The numerator becomes positive, indicating buying pressure. * **Close near Low:** The numerator becomes negative, indicating selling pressure. * **Close in Middle:** The value is near zero, indicating neutrality. This value is then multiplied by the volume. High volume on a day with a strong close amplifies the positive signal, while high volume on a weak close amplifies the negative signal.
Interpretation and Trading Signals
Traders look for divergence between the Intraday Intensity Index and the price. * **Bullish Divergence:** If prices are falling or making new lows, but the Intraday Intensity Index is rising, it suggests that "smart money" is accumulating shares, and a reversal may be imminent. * **Bearish Divergence:** If prices are rising to new highs, but the index is falling, it suggests distribution (selling) is happening beneath the surface, warning of a potential top. Confirmation is another use. If both price and the index are rising, the uptrend is considered healthy and supported by volume.
Real-World Example
A stock is in a downtrend, falling from $50 to $45. 1. **Price Action:** The stock hits a new low of $44. 2. **Indicator Action:** The Intraday Intensity Index, which had been falling, starts to rise. 3. **Analysis:** Even though the price closed lower, it closed near the top of its daily range on high volume. This indicates that buyers stepped in to absorb the selling. 4. **Signal:** This bullish divergence suggests the selling pressure is exhausted and a reversal to the upside is likely.
FAQs
Both indicators use the same core calculation (the Close Location Value). However, Chaikin Money Flow sums the values over a set period (usually 20 or 21 days) and divides by the total volume for that period, creating an oscillator. The Intraday Intensity Index is the raw daily value.
It was developed by David Bostian, a prominent market technician and strategist.
Yes, it can be applied to intraday charts (e.g., hourly), but it is most commonly used on daily charts to track institutional flows over days or weeks.
A value of zero indicates that the closing price was exactly in the middle of the high-low range, representing a balance between buying and selling pressure for that period.
Like most volume-based indicators, it is often considered a leading indicator because volume activity (accumulation/distribution) frequently precedes price movements.
The Bottom Line
The Intraday Intensity Index is a powerful tool for uncovering the hidden "smart money" flows behind price movements. By revealing whether a stock is being accumulated or distributed, it gives traders a significant edge in identifying potential trend reversals and confirming the strength of existing trends.
