The Nonlag Schaff Trend Cycle (NSTC) Indicator for MT4 is a trend-following tool developed by Doug Scaff. It combines MACD and a smoothed stochastic to deliver faster and more accurate market signals, minimizing lag compared to traditional indicators.
This indicator is suitable for any currency pair and timeframe, making it ideal for Scalping, intraday, and swing traders who rely on trend analysis.

What is the Nonlag Schaff Trend Cycle Indicator?
The NSTC is a hybrid indicator that merges:
- MACD (Moving Average Convergence Divergence) – Measures market momentum and trend direction
- Smoothed Stochastic – Helps detect overbought/oversold conditions and potential reversals
By using a non-lagging moving average, the indicator reacts quickly to price changes, providing timely buy and sell signals.
The indicator ranges between 0 and 100, with color-coded signals to make trend identification straightforward:
- Green Line – Indicates bullish momentum
- Crimson Line – Indicates bearish momentum
How to Use the Nonlag Schaff Trend Cycle Indicator
The NSTC Indicator uses key levels (25 and 75) to guide trading decisions:
Buy Signal
- Look for the indicator to rise above the 25 level.
- Confirm that the line turns green, signaling a bullish trend.
- Filter false signals by ensuring the candlestick after the trigger bar closes above the trigger bar.
- Enter a buy (long) position once confirmed.
Sell Signal
- Wait for the indicator to drop below the 75 level.
- Confirm that the line turns crimson, signaling a bearish trend.
- Filter false signals by checking that the next candlestick closes below the trigger bar.
- Enter a sell (short) position once confirmed.
By following these steps, traders can capture trend reversals and ride momentum effectively.
Trading Example
On the USD/CHF chart:
- The indicator rises above 25, turns green, signaling an uptrend, and a buy position would be profitable.
- The indicator then drops below 75, turns crimson, signaling a downtrend, and a sell position could be entered.
This color-coded system allows traders to quickly identify trend shifts and act accordingly.
