Forex Trading Guide: The DeM (DeMarker) Indicator Explained
Have you ever heard of the Dem indicator in trading?
Well, it is undoubtedly a great tool for spotting buy or sell opportunities in a diverse market. And you should use the Dem indicator strategy at least once in your trading journey.
In Beirman Capital's Indicator Introduction Series, today we will discuss the Dem Indicator, how to interpret and trade it, and the pros and cons of the style. We will also address some of the most frequently asked questions related to the DeMarker and other top indicators in trading. So, let's get started with a small introduction.
What is a Dem Indicator?
A Dem Indicator, popularly known as the DeMarker or DeMark indicator, is a widely used technical analysis tool. It compares the recent maximum and minimum prices to the high and low prices of the past period to provide key insights into the current trend.
The Demark indicator was developed by Thomas DeMark in 1980. It assists traders in identifying the current trend, overbought and oversold conditions, and trading divergence that ultimately helps traders in making buy and sell decisions.
DeMarker Indicator Formula
The formula consists of two components:
Maximum price: High - Previous High (if negative, use 0)
Minimum price: Previous Low - Low (if negative, use 0)
DeM Indicator = (High - Previous High) / [(High - Previous High) + (Previous Low - Low)] * 100
Note: If the difference is negative between the prices, you need to use zero in the calculation.
While the calculation might seem complex, you don't need to do it manually. The DEM indicator free download is available on platforms like MT4 and TradingView, where the software will perform the calculations for you.
DeMark Indicator Trading Strategies
A DeMarker indicator oscillates typically within the range of 0 to 1. However, depending on the Dem indicator settings or the platform, it can oscillate from -100 to +100.
Buy and Sell Interpretation:
- Above 0.70: Indicates strong bullishness – consider a buy position.
- Below 0.30: Indicates strong bearishness – consider a sell position.
Overbought and Oversold Conditions:
- Above 0.70: Market is overbought – potential shorting opportunity.
- Below 0.30: Market is oversold – potential buying opportunity.
Divergence:
- Bullish Divergence: Price makes a lower low, while Demarker makes a higher low – suggests a buy.
- Bearish Divergence: Price makes a higher high, while Demarker makes a lower high – suggests a sell.
How to Use the DeMarker Indicator Strategy
Select an Asset: Choose your trading instrument – currency pair, commodity, index, or stock.
Select Time Frame & Plot Indicator: Use platforms like MT4, MT5, or TradingView. Use the popular DeMark 13 indicator (period = 13).
Use Supporting Indicators: Combine DeMarker with tools like RSI, Fibonacci Retracement, Bollinger Bands, or EMA (available in MT4) to confirm signals.
Place Trades:
Go short above 0.70
Go long below 0.30
Always use a stop-loss and take-profit strategy

This article on the DeM indicator is pretty useful. I've used technical analysis tools before, and understanding how they work is key. It's interesting how the Dem indicator compares recent and past prices. I'm curious, though, how accurate are the buy and sell signals it gives? And have you had any personal experiences trading with indicators like this? It'd be great to hear some real - world examples.
