How the Schaff Trend Signal EMA Works
The indicator uses two main components:
- Exponential Moving Average (EMA) – Smooths Price Action to determine trend direction.
- Schaff Trend Cycle (STC) – Uses a fast and slow EMA to identify cycles and trend momentum.
- Oscillates between 0 and 100:
- 0–20 zone → Oversold, potential buy signals
- 80–100 zone → Overbought, potential sell signals
- Oscillates between 0 and 100:
Signal Interpretation
- Buy Signal – When the STC line (light sea green) crosses above the EMA (red line) in the oversold zone.
- Sell Signal – When the STC line crosses below the EMA in the overbought zone.
Traders can use stop loss orders at recent swing highs or lows to manage risk.
Trading Strategy
Buy Setup
- Wait for STC and EMA crossover in the oversold zone (0–20).
- Confirm the signal with price action or trend context.
- Enter a Buy trade at candle close.
- Place stop loss below the recent swing low.
- Exit when the STC line reverses or enters the overbought zone.
Sell Setup
- Wait for STC and EMA crossover in the overbought zone (80–100).
- Confirm trend direction or price action.
- Enter a Sell trade at candle close.

Using the STC and EMA combination helps filter false signals and improves the accuracy of trend reversal trades.
