3. HOW IT WORKS

Core Calculation & Logic

The Simple Decycler Oscillator calculates momentum shifts by filtering out market cycles, allowing traders to identify underlying trends. Its mathematical basis involves high-pass filtering to isolate price movements from noise.

This indicator helps traders recognize potential entry and exit points by signaling changes in market momentum, making it easier to navigate volatile conditions.

BUY and SELL Signal Conditions

BUY Signal — When does it appear? A BUY signal occurs when the fast high pass oscillator (deo2) crosses above the slow high pass oscillator (deo).

SELL Signal — When does it appear? A SELL signal occurs when the fast high pass oscillator (deo2) crosses below the slow high pass oscillator (deo).

Signal Confirmation: Traders will see a color change in the indicator lines, accompanied by an alert if enabled, indicating potential trade opportunities.

Recommended Action: For confirmation, traders should look for higher time frame alignment and consider placing stop-loss orders below recent swing lows.

Step-by-Step Workflow

Step 1: Set Up the Indicator Add the Simple Decycler Oscillator to your chart and adjust the parameters as needed.

Step 2: Monitor Signals Watch for crossovers between the fast and slow oscillators to identify potential trade signals.

Step 3: Confirm with Price Action Look for supporting price action or trend confirmation on higher time frames before entering trades.

Step 4: Manage Risk Set appropriate stop-loss levels based on recent price action to mitigate risk.

Step 5: Adjust Settings as Needed Fine-tune the oscillator settings based on your trading style and market conditions.
