AMANTUS TSI
AMANTUS TSI — True Strength Index with Signal Line, Zones & Cross Markers
What it is
A clean, no-nonsense implementation of William Blau's True Strength Index — a double-smoothed momentum oscillator that filters out price noise while staying responsive to real shifts in strength. Paired with an SMA signal line, overbought/oversold zones and clear crossover markers, it gives you a complete momentum read-out in one pane.
How it works
Double smoothing is what makes TSI different from RSI or a plain momentum line: it reacts to sustained pressure, not single-bar spikes. In practice this often makes TSI more informative than RSI — especially in precious metals, where sharp intraday swings keep RSI pinned in extreme zones while TSI still shows whether the underlying momentum is building or fading.

How it works
- Price change (close − previous close) is smoothed twice with EMAs (25, then 13).
- The absolute price change is smoothed the same way.
- TSI = 100 × (smoothed change / smoothed absolute change), bounded between −100 and +100.
- A 14-period SMA of the TSI serves as the signal line.

What you see
- TSI line (violet) and Signal line (amber).
- Gap fill: green when TSI is above the signal, red when below — momentum direction at a glance.
- Zone lines at ±25 (adjustable) and a dotted zero line.
- ▲ / ▼ markers on bullish and bearish crossovers.
How to read it
- TSI crosses above the signal → momentum turning bullish; above zero → bulls in control.
- TSI crosses below the signal → momentum turning bearish; below zero → bears in control.
- Readings beyond ±25 flag stretched conditions — crosses from these zones back toward zero are the classic mean-reversion setups.
- Divergence between TSI peaks/troughs and price often precedes a turn.
Settings
- Long smoothing (25), Short smoothing (13), Signal SMA (14)
- Zone boundary (±25)
- Toggle crossover markers and gap fill
Alerts
Two built-in alert conditions: TSI BULL cross and TSI BEAR cross.
Notes
- Works on any symbol and timeframe. Developed and tested on XAUUSD.
- Signals are confirmed at bar close and do not repaint afterwards.
- Early values depend on the amount of loaded history (EMA warm-up).
