De Marker indicator showing price relation to previous ranges for trend analysis

Fundamentals

Understanding DeMarker

DeMarker technical indicator (DeM) is based on the comparison of the period maximum with the previous period maximum.

Below is a DeMarker (DeM) indicator strategy for automated trading. DeMarker measures buying and selling pressure with values between 0 and 1, making it straightforward to automate.

How DeMarker Works in Automated Trading

DeM Values: Range from 0 to 1 (sometimes expressed as 0-100)
DeM above 0.5: Buying pressure increasing - potential upward momentum
DeM below 0.5: Selling pressure increasing - potential downward momentum
Extreme Levels: Above 0.7 or below 0.3 indicate potential trend exhaustion

DeMarker technical indicator (DeM) is based on the comparison of the period maximum with the previous period maximum. It helps identify potential trend exhaustion through price comparisons between adjacent periods, making it valuable for algo trading strategies.

DeMarker Strategy 1: Overbought/Oversold (0.7/0.3)

The DeMarker Midline Crossover strategy uses the 0.5 threshold to identify shifts in buying and selling pressure, testing entries when momentum changes direction.

Setup in Tradeworks

Add DeMarker indicator to your strategy
Set parameters: Period = 14 (standard)
Configure entry conditions:
- Open Position Buy Signal: DeMarker crosses from below to above 0.5
- Open Position Sell Signal: DeMarker crosses from above to below 0.5

Trade Management

Stop Loss Exit Signal:
- For longs: Set condition to 'Strategy symbol BID price is less than (Previous bar close - (2Ãƒâ€” ATR))'
- For shorts: Set condition to 'Strategy symbol ASK price is greater than (Previous bar close + (2Ãƒâ€” ATR))'
Take Profit Exit Signal:
- For longs: Set condition to 'Strategy symbol BID price is greater than (Previous bar close + (2Ãƒâ€” ATR))'
- For shorts: Set condition to 'Strategy symbol ASK price is less than (Previous bar close - (2Ãƒâ€” ATR))'
Testing note: Compare chart intervals and instruments in backtesting before deciding where this setup fits your approach.
Common Pairs: Major pairs with clear trend cycles (EUR/USD, GBP/USD)
Filter: Add trend alignment (require price above Moving Average (50) for long entries)

DeMarker Strategy 2: Zero-Line Crossover

The DeMarker Trend Exhaustion strategy tests whether extreme DeMarker readings can help identify trend exhaustion and possible reversal areas.

Setup in Tradeworks

Add DeMarker indicator to your strategy
Set parameters: Period = 14
Configure entry conditions:
- Open Position Buy Signal: DeMarker below 0.3 (oversold) AND DeMarker crosses from below to above 0.3
- Open Position Sell Signal: DeMarker above 0.7 (overbought) AND DeMarker crosses from above to below 0.7

Trade Management

Stop Loss Exit Signal:
- For longs: Set condition to 'Strategy symbol BID price is less than (Previous bar close - (2Ãƒâ€” ATR))'
- For shorts: Set condition to 'Strategy symbol ASK price is greater than (Previous bar close + (2Ãƒâ€” ATR))'
Take Profit Exit Signal:
- For longs: Set condition to 'DeMarker is greater than 0.6'
- For shorts: Set condition to 'DeMarker is less than 0.4'
Common Timeframe: 4-hour to daily charts for trend exhaustion signals
Common Pairs: Pairs with clear trend cycles (EUR/USD, GBP/USD, EUR/GBP)
Filter: Add ADX above 25 to ensure trending market (not ranging)

DeMarker Strategy 3: Trend Filter

Beyond standalone strategies, DeMarker can be tested as a filter for other trading systems. Its price-extreme logic can support confirmation rules from other indicators or help flag possible trend-reversal conditions.

Using DeMarker as Filter

Entry Confirmation: Only enter trades when DeMarker aligns with your primary signal direction
Trend Exhaustion Warning: Exit or reduce position size when DeMarker reaches extreme levels (above 0.7 or below 0.3)
Divergence Trading: Look for price/DeMarker divergence for early reversal signals
Multi-Timeframe: Use DeMarker on higher timeframe for trend direction, lower for entry timing

Combining with Other Indicators

Trend Indicator: Add Moving Average to confirm trend direction
Volatility: Use Average True Range (ATR) for dynamic stop losses
Momentum: Combine with RSI for stronger confirmation
Pattern Recognition: Use with Fractals for support/resistance confirmation

For Bot Developers: Implementation Tips

Choosing DeMarker Parameters

Sensitivity: Shorter periods (7-10) for faster signals but more false positives
Baseline: Standard 14 is a common starting point before testing alternatives
Smoothing: Higher periods (20-28) for cleaner signals but slower response
Timeframe Adjustment: Use standard settings for 1h-4h charts, longer periods for daily/weekly

Combining with Other Indicators

Trend Filter: Add Moving Average to confirm trend direction
Volatility Adjustment: Use Average True Range (ATR) for dynamic stop losses
Confirmation: Add MACD for additional momentum confirmation
Multi-Timeframe: Use DeMarker on lower timeframe for entry timing, higher for trend context

Manageable Beginner Setup

Start Simple: Use DeMarker 0.5 crossover with Moving Average trend filter
Add Confirmation: Combine with RSI or Stochastic for stronger signals
Test Extensively: Backtest with different DeMarker periods across multiple currency pairs
Paper Trade First: Always run strategies on a demo/paper account before considering going live

Questions

Frequently Asked Questions

What is the DeMarker indicator and how does it work? +

The DeMarker (DeM) indicator is a technical analysis tool that compares the most recent price maximum and minimum with the previous period's values. It measures buying and selling pressure by analyzing price relationships between adjacent periods, outputting values between 0 and 1.

How do I use DeMarker in automated trading? +

In Tradeworks, you can configure DeMarker signals with simple threshold conditions: Buy signals trigger when DeMarker crosses above 0.5 (increasing buying pressure), and sell signals trigger when it crosses below 0.5 (increasing selling pressure). Its clean 0-1 range makes threshold programming straightforward.

What's the difference between DeMarker and RSI? +

While both are bounded oscillators (0-1 for DeMarker, 0-100 for RSI), they measure different things. DeMarker compares period highs/lows with previous periods, while RSI measures price change magnitude. DeMarker is often used to test trend-exhaustion conditions, while RSI is often used to test momentum conditions.

Can DeMarker be used as a standalone indicator? +

DeMarker can be tested as a filter or confirmation tool, especially when combined with other indicators. Use it alongside trend indicators (like Moving Average) to filter signals in the trend direction, or combine with volatility indicators (ATR) for dynamic stop loss placement.
