How to Build a Forex Trading Indicator How to Build a Forex Trading Indicator
In the dynamic world of financial trading, understanding how to build a trading indicator is a valuable skill. This article is designed to navigate you through the essential steps of creating your own trading indicators, offering a blend of technical and practical insights to potentially enhance your market analysis and trading decisions.
Understanding Trading Indicators
Trading indicators are essential tools in analysing financial markets, offering traders valuable insights into market trends and potential trading opportunities. These mathematical calculations are applied to various market data points like price, volume, and sometimes open interest. In forex trading, indicators play a crucial role in analysing currency pair movements.
There are several types of indicators, each serving a specific purpose:
- Trend indicators help identify the direction of market movements.
- Momentum indicators gauge the speed of these movements.
- Volume indicators look at trading volumes to understand market strength.
- Volatility indicators provide insight into the stability or instability of currency prices.
While there are hundreds of indicators to choose from, some traders choose to develop their own based on their unique market observations.
Basic Components of a Trading Indicator
The core components of a trading indicator are price, volume, and time. These elements are fundamental in analysing market data and building various tools.
- Price: The most critical component, price, is used in almost every trading indicator. It includes open, high, low, and close prices of trading instruments. Price data is essential for constructing trend-following tools like moving averages and oscillators like the Stochastic RSI.
- Volume: Volume indicates the number of contracts traded in a given period. It provides insights into the strength or weakness of a market move. Volume-based tools, like the Volume Oscillator or On-Balance Volume (OBV), help traders understand the intensity behind price movements.
- Time: Indicators use time periods to analyse market trends. This could be short-term (minutes, hours), medium-term (days, weeks), or long-term (months, years). Time frames influence the sensitivity of an indicator, with shorter periods typically offering more signals.
Choosing the Right Data and Tools
Selecting appropriate data and tools is a critical step in building effective trading indicators. For data, accuracy and relevance are paramount. Traders typically use historical price data alongside volume data.
For tools, traders consider user-friendly platforms that offer robust functionality for creating and testing tools. Platforms like TradingView and MetaTrader offer extensive libraries and community support, facilitating the development of customised indicators.
Additionally, programming languages like Python, C# and R, known for their data analysis capabilities, can be powerful tools for creating more complex indicators. FXOpen’s TickTrader, for instance, supports custom C#-based indicators and offers powerful backtesting tools.
How to Build a Trading Indicator: A Step-by-Step Walkthrough
Developing an indicator involves several key steps, each crucial to ensure the final tool is effective and aligns with your trading strategy.
1. Define the Objective
Begin by clearly defining what you want your tool to achieve. Is it to identify trends, pinpoint entry and exit points, or gauge market volatility? Your objective will guide the type of indicator you develop, such as trend-following, momentum, or volatility-based.
2. Select the Formula
Choose or develop a mathematical formula that your tool will use. This could be a simple moving average, a complex algorithm involving multiple data points, or something entirely unique. The formula should reflect the market phenomena you aim to capture.
3. Coding the Indicator
Translate your formula into code. If using platforms like TradingView, MetaTrader or TickTrader, their scripting languages (Pine Script for TradingView, MQL4/5 for MetaTrader, C# for TickTrader) are designed for this purpose. Ensure the code is clean, well-documented, and easily adjustable.
4. Incorporate Visualisation
Decide how the indicator will visually appear on the chart or in a separate window. This could be in the form of lines, bars, dots, or other graphical representations. The visual aspect should make it easy to interpret signals at a glance.
5. Backtesting
Before applying your indicator in live trading, it’s crucial to backtest it using historical data. This topic is expanded on below.
Testing and Refining Your Indicator
Testing and refining your trading indicator is a critical phase in its development, ensuring its potential effectiveness and reliability in real market conditions.
- Backtesting: This is the process of testing your indicator against historical data. Backtesting helps evaluate how it would’ve performed in different market scenarios, revealing its strengths and weaknesses. It's essential to test over various time frames and market conditions to ensure robustness.
- Analysing Results: Assess the indicator's accuracy, consistency, and responsiveness to market changes. Look for patterns in its performance, such as frequent false signals or lag in response to price movements.
- Refinement: Based on the backtesting results, refine your indicator. This could involve tweaking the formula, adjusting parameters like time periods or thresholds, or enhancing the visualisation for clearer signals.
- Forward Testing: After adjustments, conduct forward testing in a simulated or live trading environment with real-time data. This helps verify its performance in current market conditions.
Remember, no indicator is perfect; the goal is to develop a tool that consistently aids in your trading outcomes.
The Bottom Line
The journey of building an indicator is both challenging and rewarding. From selecting the right data and tools to carefully coding and testing your creation, each step plays a vital role in crafting an effective aid for trading decisions.

The Fundamental Concepts of Technical IndicatorsTrading indicators are essential tools used by traders and investors to analyze price data, identify trends, and make informed decisions in financial markets. They provide valuable insights into market dynamics, helping market participants gain a competitive edge. This comprehensive explainer will delve into what trading indicators are, how they are utilized, and the differences between two prominent strategies: trend following and mean reversion. Additionally, we will explore the importance of using binary and discrete indicators together to enhance trading effectiveness.
Part 1: Understanding Trading Indicators
1.1 Definition of Trading Indicators
Trading indicators are mathematical calculations based on price, volume, or open interest data that provide graphical representations of market conditions. These calculations help traders visualize price trends, momentum, volatility, and potential reversals. Indicators serve as a supplementary layer of analysis, offering a structured and objective approach to interpreting market behavior.
1.2 Types of Trading Indicators
Trend Indicators: Identify the direction and strength of prevailing trends, such as Moving Averages (MA), Moving Average Convergence Divergence (MACD), and Ichimoku Cloud.
Oscillators: Measure overbought and oversold conditions, such as Relative Strength Index (RSI), Stochastic Oscillator, and Commodity Channel Index (CCI).
Volume Indicators: Assess trading volume to confirm price movements, like On-Balance Volume (OBV) and Volume Weighted Average Price (VWAP).
Volatility Indicators: Gauge the level of price fluctuations, including Bollinger Bands and Average True Range (ATR).
Part 2: Utilizing Trading Indicators
2.1 Trend Following Strategy
Trend following is a popular trading strategy that capitalizes on the continuation of established trends. Traders using this approach seek to identify uptrends or downtrends and ride them for extended periods. Trend following indicators are ideally suited for identifying the direction of a trend and capturing profits during strong market movements.
Example of Trend Following Indicator: Fourier Smoothed Stochastic (FSTOCH)
(Indicators like the FSTOCH help traders reveal underlying trends in the market)
The Fourier Smoothed Stochastic is an advanced tool that utilizes the Stochastic Oscillator in combination with Fourier Transform analysis to identify and ride prevailing trends. By providing smoother signals, it helps traders stay on course with the established trend, allowing for more accurate entries and exits. Its ability to filter out market noise makes it an ideal choice for trend followers seeking a clearer view of market momentum, enabling them to capitalize on prolonged price movements.
2.2 Mean Reversion Strategy
Mean reversion is a counter-trend strategy that assumes prices will revert to their average or mean over time. Traders using this approach aim to profit from price reversals when an asset's price deviates significantly from its historical average. Mean reversion indicators are ideal for identifying overbought and oversold conditions and anticipating potential reversals.
Example of Mean Reversion Indicator: Bollinger Bands Percentile (BBPct)
(The BBPct indicator marks out price extremes which may lead to potential reversals)
The BBPct (Bollinger Bands Percent) is an indicator designed for mean reversion trading strategies. It utilizes Bollinger Bands to determine overbought and oversold conditions in the market. The indicator calculates the percentage of the current price's position within the Bollinger Bands' upper and lower boundaries. When the price is near the upper band, it suggests an overbought condition, indicating a potential mean reversion towards the lower band. Conversely, when the price is close to the lower band, it indicates an oversold condition, suggesting a possible mean reversion towards the upper band. Traders can use this information to identify potential reversal points and make informed decisions to capture price movements back towards the mean.
Part 3: Trend Following vs. Mean Reversion
3.1 Key Differences
Direction: Trend following aims to identify and ride established trends, while mean reversion seeks to capitalize on price reversals.
Risk Profile: Trend following strategies typically involve higher risk, as traders enter positions in the direction of the trend, which may be challenging to time accurately. Mean reversion strategies are often considered less risky as traders expect price reversals to occur relatively soon after significant deviations from the mean.
Market Conditions: Trend following tends to perform well in trending markets, while mean reversion thrives in ranging or sideways markets.
3.2 Combining Trend Following and Mean Reversion
While trend following and mean reversion strategies have distinct approaches, they can complement each other when used in confluence. Combining both strategies can provide a more comprehensive view of the market and reduce reliance on a single indicator. For example:
Confirming Trend Reversals: Mean reversion indicators can be used to confirm potential trend reversals identified by trend-following indicators, increasing the probability of successful entries and exits.
Managing Risk: Trend following indicators can help traders stay in trends longer and avoid premature exits when using mean reversion strategies.
Identifying Range-Bound Markets: Mean reversion strategies can be employed during periods of low volatility or when the market lacks a clear trend, while trend following indicators can be set aside until a new trend emerges.
Part 4: Binary and Discrete Indicators
4.1 Binary Indicators
(The Super Schaff gives out binary signals when it detects a potential change in trend)
Binary indicators provide straightforward, yes-or-no signals, indicating the presence or absence of a particular condition. Examples include Moving Average Crossovers and Super Schaff, which produce buy (long) or sell (short) signals when specific conditions are met.
4.2 Discrete Indicators
(The Volume-Trend Sentiment displays the overall implied sentiment based on volume and price action)
Discrete indicators generate signals based on a range of values or levels. These indicators offer more nuanced insights into market conditions, allowing traders to interpret the strength or weakness of signals. Examples include RSI and VTS.
Part 5: The Importance of Using Both
5.1 Diverse Perspectives
Combining binary and discrete indicators provides traders with diverse perspectives on market conditions. Binary indicators offer clear entry and exit signals, while discrete indicators offer a finer understanding of price trends and potential turning points.
5.2 Enhanced Decision-Making
Using both types of indicators helps traders make more informed and confident decisions. By cross-referencing binary and discrete signals, traders can filter out false signals and identify high-probability trading opportunities.
Conclusion:
Trading indicators play a vital role in modern financial markets, providing traders and investors with valuable insights into price trends, momentum, and market conditions. Trend following and mean reversion strategies offer distinct approaches to trading, each with its unique advantages and risk profiles. However, combining these strategies and utilizing both binary and discrete indicators can provide a comprehensive and powerful toolkit for traders seeking consistent success in the dynamic world of finance.

Moving Average | Two Profitable Ways to Use 📊
Hey traders,
In this post, we will discuss two efficient ways to apply the moving average(s) indicator in your trading.
Please, note that the settings for a moving average depend on many factors and can not be universal. Time frame, your style of trading and many other factors should be taken into consideration when you define the settings.
1️⃣The first very efficient way to apply moving average is to consider that to be a strong support/resistance. Such a method is appropriate for trend-following traders.
A very important condition to note applying MA as the structure is that the market should be trending: it should trade in a bullish or bearish trend, not in sideways.
📍In a bullish trend, a moving average will provide you a relatively safe point for buying the market after a pullback. Quite often after a test of MA, the price tends to bounce all the way up to a current high and even go higher to the next highs.
📍In a bearish trend, a moving average will serve as a strong resistance and quite often will indicate a completion point of a retracement leg after a strong bearish impulse.
2️⃣The second way to apply moving average is to apply a combination of 2 MAs with different settings (one with a bigger and one with a smaller length). Such a method is usually applied by counter-trend traders.
And again, a very important condition to note, is that if you want to apply this method efficiently, remember that the market must be trending, it should be bullish or bearish.
Your task will be to track an intersection of two MAs.
📍In a bullish trend, a crossing of two moving averages with a high probability will indicate a trend violation and initiation of a new bearish trend.
Such a signal usually serves as a trigger to open a short position.
📍In a bearish trend, a crossing of two moving averages will signify a violation of a bearish trend and the start of a new bullish trend.
The intersection by itself will be a signal to open a long position.
Your task as a trader is to find the most accurate inputs for MAs. With backtesting and experience, you will find the settings applicable to your trading style.
