# TSI Oscillator

## TSI Oscillator:

The True Strength Index (TSI) is a momentum oscillator that measures trend strength via double-smoothed price changes, oscillating between -100 and +100 (typically -25 to +25). It filters noise better than RSI using EMAs. In the screenshot (TradingView, Sep 22, 2025), it's part of "Momentum Concepts Pro v1.0," showing candlesticks (\~661-665 USD) above, with TSI lines below: white (fast TSI), yellow (signal), red zero line, and green (histogram/Z-score) for extremes.

#### **How to Use the TSI Oscillator**

**Components**

* **White Line:** Fast TSI for momentum direction.
* **Yellow Line:** Slow signal for confirmation.
* **Red Zero Line:** Bullish above, bearish below.
* **Green Line/Zones:** Overbought (red, \~2.0) vs. oversold (green, \~-2.0).

**Setup on TradingView**

* Add "Momentum Concepts Pro" or standard TSI.
* Defaults: 25/13 EMAs; adjust for timeframe (e.g., intraday like screenshot's 10-min candles).

**Key Signals**

* **Centerline Cross:** Above zero = bullish bias; below = bearish.
* **Signal Cross:** White over yellow = buy (esp. above zero); white under = sell.
* **Zones:** +25 overbought (sell warning); -25 oversold (buy potential). Watch hooks/reversals.
* **Divergences:** Price vs. TSI mismatches signal reversals.

**Strategies**

* **Trend Follow:** Buy on bullish crosses in uptrends; short in downtrends.
* **Reversals:** Long from oversold hooks; short from overbought.
* **Exits:** At opposite zones or reverse signals; use stops at swings/EMAs.
* Avoid choppy flats around zero; combine with price structure. Backtest before trading.
