Introduction to the Trend Intensity Index (TII)
The Trend Intensity Index (TII) is a technical analysis indicator used to measure the strength and persistence of a trend. It was developed to help traders determine whether an asset is in a strong uptrend, a downtrend, or moving sideways. Unlike traditional trend indicators like Moving Averages or the Average Directional Index (ADX), TII focuses on comparing the asset’s closing price against a moving average to assess the intensity of the trend.
Calculating the Trend Intensity Index (TII)
The Trend Intensity Index is calculated using the following steps:
- Select a moving average period (typically a 20-period simple moving average (SMA)).
- Determine the number of periods where the closing price is above the SMA.
- Calculate the relative position of the closing prices compared to the moving average.
- Normalize the value on a scale of 0 to 100.

A TII above 80 indicates a strong uptrend, while a TII below 20 signals a strong downtrend.
Trading Strategies Using Trend Intensity Index (TII)
1. Trend Confirmation Strategy
Concept: Traders use the TII to confirm whether an existing trend is strong enough to continue or if it is losing momentum.
Buy Signal:
- TII crosses above 50 from below.
- TII stays above 60-70, confirming a strong uptrend.
- Price remains above the 20-period SMA.
Sell Signal:
- TII crosses below 50 from above.
- TII stays below 30-40, confirming a strong downtrend.
- Price remains below the 20-period SMA.
Example: Suppose a stock’s price is consistently closing above the 20-period SMA, and the TII crosses above 60. This confirms a strong bullish trend, signaling a buy entry.
2. Overbought and Oversold Trading Strategy
Concept: Similar to the RSI (Relative Strength Index), traders use TII to identify overbought and oversold conditions.
Buy Signal:
- TII falls below 20, indicating an oversold market.
- Price finds support and begins reversing upward.
Sell Signal:
- TII rises above 80, indicating an overbought market.
- Price shows signs of resistance and potential reversal.
Example: If a stock’s TII drops to 15, and price forms a reversal candlestick pattern (such as a bullish engulfing), a trader might consider entering a long position.
3. Divergence Trading Strategy
Concept: Divergence occurs when the price moves in the opposite direction of the TII, signaling potential trend reversals.
Bullish Divergence:
- Price makes lower lows, but TII makes higher lows.
- Indicates weakening downtrend and possible reversal.
Bearish Divergence:
- Price makes higher highs, but TII makes lower highs.
- Indicates weakening uptrend and potential reversal.
Example: If a stock is making new highs, but TII is declining, this suggests that momentum is weakening, and a bearish reversal could be imminent.
4. Breakout Trading Strategy
Concept: When TII confirms a breakout, traders can confidently enter trades in the breakout direction.
Buy Signal:
- Price breaks above a resistance level.
- TII crosses above 50 and continues to rise.
Sell Signal:
- Price breaks below a support level.
- TII drops below 50 and continues declining.
Example: If a stock breaks above a key resistance level at $100, and TII jumps from 45 to 70, this signals strong buying momentum, confirming the breakout.
5. Trend Reversal Strategy with Moving Averages
Concept: Combine TII with moving averages for early trend reversal detection.
Buy Signal:
- Price crosses above the 50-period SMA.
- TII moves above 50, confirming strength.
Sell Signal:
- Price crosses below the 50-period SMA.
- TII drops below 50, indicating weakness.
Example: If a stock has been in a downtrend but suddenly moves above the 50-day SMA, and TII crosses above 50, it suggests a bullish reversal.
6. TII + MACD Strategy
Concept: Combining TII with the Moving Average Convergence Divergence (MACD) increases trading accuracy.
Buy Signal:
- TII crosses above 50.
- MACD histogram turns positive.
- Price confirms higher lows.
Sell Signal:
- TII crosses below 50.
- MACD histogram turns negative.
- Price confirms lower highs.
Example: If TII is at 65, MACD is crossing above the signal line, and price is breaking out, this signals a high-probability buy setup.
Conclusion
The Trend Intensity Index (TII) is a valuable tool for assessing trend strength, confirming breakouts, identifying overbought/oversold levels, and detecting divergences. By integrating TII with other indicators like moving averages, MACD, and support/resistance levels, traders can develop high-probability trading strategies.
However, no indicator is foolproof. Traders should always use risk management, set stop-loss orders, and confirm signals with multiple indicators before placing trades. By mastering the TII, traders can gain an edge in trend-based trading strategies and improve their overall trading performance.
