iDeMarker Technical Indicators MQL4 Reference


This guide will delve into the DeMarker Indicator, exploring its calculation, interpretation, and practical application in forex trading. Thus, we are now deploying the DeMarker indicator to identify potential price levels where a change in the price direction may occur soon. Here we have a USD/JPY daily chart that trades in a downtrend as the price action has been creating a series of the lower highs and lower lows. The indicator’s band moves from 0 to 100%, and the overbought and oversold zones, like for the indicators, described above, are the zones above 60 and below 40 respectively.

  • Finally, when the price went beyond the oversold zone on June 13, we can easily identify the low in the period when the ticker had been below 40, according to TD DeMarker indicator I.
  • The Demarker indicator is named after Tom Demarker who claims to have developed this indicator to overcome the shortcomings of other overbought/oversold oscillators.
  • The DeM indicator attempts to convey price exhaustion, but timing is a weakness that can be overcome using another indicator for validation.
  • With a solid understanding of its key components and the ability to implement it effectively in trading strategies, traders can harness the DeMarker indicator’s full potential on IQ Option.
  • Skill in interpreting and understanding DeM signals must be developed over time.
  • If both the indicator and the price are in an uptrend, the interpretation is that the existing price pattern will continue to develop.
  • The DeM line passing through the overbought line should be seen as a warning that the uptrend may be running out of steam and that a reversal could be on the way.

For example, set the period to 14, the overbought line to 70, and the oversold line to 30. When the oscillating line passes above 0.70, that is an indication that the market conditions may be overbought. When the oscillating line passes below 0.30, that is an indication that the conditions may be oversold. DeMMIN is a value derived from comparing the minimum value for the current bar to the minimum value of the previous bar over “n” periods. DeMMAX is a value derived from comparing the maximum value for the current bar to the maximum value of the previous bar over “n” periods. From a market perspective, this method of the calculation most effectively takes into account the current DeMand for the asset.

Exiting the overbought/oversold zones

The indicator typically has lines drawn at the “0.30” and “0.70” values as warning signals. Values exceeding either boundary are deemed riskier, while values within are considered low risk. Overbought and oversold conditions are imminent when the curve crosses over these boundary lines, respectively. Unlike the Relative Strength Index (RSI), which is perhaps the best-known oscillator, the DeMarker indicator focuses on intra-period highs and lows rather than closing levels. DeMarker belongs to the group of normalized oscillators; its values lie between 0% and 100%; 100% is marked as 1.

  • Market timing is the ability to get in and out of the market with a high degree of accuracy.
  • Here we have a USD/JPY daily chart that trades in a downtrend as the price action has been creating a series of the lower highs and lower lows.
  • The received value becomes the DeMarker indicator numerator and is divided by the same value plus the sum of differences between price lows of the previous and current bars.
  • DeMark suggests that the price action is directly affected by the supply/demand ratio.
  • At this moment, we have a confluence of two bullish signals – market is oversold according to DeMarker, and the price action has approached the first Fibonacci extension support.

In 2020, he was awarded a Lifetime Achievement Award by the Market Technicians Association. Although DeM is advertised as a method to time trend reversals, in several cases, large price movements that followed a signal maintained the direction of the existing trend. According to the paper’s authors, “these results contradict the design of the indicator and make it difficult to grasp the economic rationale behind it, which is assumed to be obvious.” The first conclusion from this research is that the number of signals the DeM indicators produce is small and rarely occurs. Compared to a simple buy-and-hold strategy, their results show that, in most cases, there is a limited range of holding days for which the indicators have predictive power. The knowledge and experience he has acquired constitute his own approach to analyzing assets, which he is happy to share with the listeners of RoboForex webinars.

ZigZag AutoChannel Indicator

In this setting, which is a default setting on MT4, the base value is 0.5, while the default time span for the calculation of values is 14 periods. The default setting has overbought and oversold lines set at 0.7 and 0.3 respectively. When the reading stays in between these two levels, DeM indicates that the market is likely trading sideways and implies lower volatility.


That even implicit or conflicting signals of the indicator are considered to be the key points for a kickback start (see here). Except the color scheme, only one parameter – the averaging period is used (or number of bars for the calculation). An uptrend coupled with a falling DeM value indicates that the uptrend is losing momentum and may suffer a reversal. I will describe other useful DeMark’s indicators and explain how to apply them to BTCUSD trading in my next articles.

Thomas Demark created the DeM in an attempt to measure the demand for the underlying currency pair. The DeM indicator relates recent price action to recent price ranges. Traders use the index to determine overbought and oversold conditions, assess risk levels, and time when price exhaustion is imminent. It has become a helpful tool to gauge the directional trend of the market since it tends to level out during a trend before signalling a coming change. DeM compares the most recent maximum and minimum prices to the previous period’s equivalent price. In essence, the indicator generates values to help you identify the directional bias of the market, and potential changes in the trend direction.

  • As with any technical analysis tool, the DeMarker indicator uses pricing behaviour in the past to forecast future behaviour.
  • Comparison of the extreme prices for the several previous periods increases the sensitivity of the DeMark indicator and reduces the risk of a wrong decision.
  • The Demarker indicator is an oscillator that displays potential overbought and oversold conditions in the market.
  • The buy and sell signals sent by this indicator are interpreted in the same way as those sent by TD DeMarker I and II.
  • So, while useful on its own, like any technical indicator, the DeMarker indicator is better combined with other indicators to confirm its signals.

As a result, a turn from this area of the «exhaustion» is more reliable. Using longer periods of the calculation allows you to monitor confidently the long-term trend; short periods allow you to open a trade at a point with a minimum risk level (for details). Thomas Demark was a prolific writer and businessman in the United States who cut his teeth as an officer of National Investment Services, a manager of multi-billion-dollar pension funds. In 1982, he formed an investment advisory firm, DeMark Investment Advisory, serving major clients like George Soros, Goldman Sachs, and IBM. He is best known in the forex trading industry as a supplier of specialised software to support market-timing regimens, developing over 70 tools during his 50-year career. Over the same period, he authored several books on market-timing techniques.

The setups are straightforward, but every trading opportunity may not work out as well as this one. Practice using the demarker indicator and incorporate it into your daily routine. Now observe how the red line foreshadows pricing reversals ahead of the Bollinger centre line. These forecasts occur when the red line crosses the Blue Bollinger moving average.


The value of this unique property can be observed by taking another look at the overview chart depicted in the introduction. As with any technical indicator, a DeMarker indicator will never be 100% correct. False signals can occur, but the positive signals are consistent enough to give a forex trader an “edge”.

After the price chart reverses upwards, open a buying trade with an SL behind the last low. The indicator is displayed in a separate window under the price chart; it looks like a line moving between 0 and 1. The area above 0.7 is called the overbought area where a reversal downwards may form. The area below 0.3 is called the oversold area, where we may consider buying. The DeMarker indicator is included in most of the popular trading platforms.

In strong trends they will follow the same pattern as the price, but towards the end of a trend the oscillators will fail to confirm the movement. The result is multiplied by the trading volume of the current period and is added as a progressive total to the indicator value. As soon as all these conditions are satisfied, it can be interpreted as a sell signal. Traders utilize forex indicators as instruments for market analysis and to… Looking at this period is important because it affects your trading strategy. In most charts, the indicator uses a period of 14 but this can be changed.
