Trendoscope™| Technicals of Technical Indicators

Let's delve into technical indicators. Essentially, they're mathematical computations based on historical price movements. Technical indicators exclusively depict past events and do not foretell future occurrences. So, why do traders employ them? Traders commonly utilize technical indicators to scrutinize previous price patterns, extracting insights that may guide future expectations.

It's vital to grasp that technical analysis isn't an infallible science; it's more akin to an art form. Seasoned traders combine it with robust risk management and discipline, effectively leveraging these tools to tilt the odds in their favor.

Complexity of Technical Indicators

The complexity of deriving and implementing technical indicators varies widely, depending on the indicator itself and your level of programming and mathematical expertise. Here's a breakdown:

Simple Indicators: Some basic indicators, like moving averages or simple trend lines, are relatively easy to understand and implement. These often require basic mathematical calculations and are commonly available in charting platforms like TradingView.

Intermediate Indicators: As you move into more intermediate indicators like the Relative Strength Index (RSI) or Stochastic Oscillator, Bollinger Bands, Ichimoku Clouds, you'll encounter more complex mathematical calculations involving historical price data. While these can be challenging for beginners, they are well-documented, and you can often find libraries or pre-built functions to help with implementation.

Advanced Indicators: Advanced indicators like or Elliott Wave Theory, Harmonic Patterns, Chart Patterns, Trend Lines, Candlestick Patterns etc. can be quite complex to both understand and implement. They often involve intricate mathematical models and may require a deep understanding of financial markets.

Custom Indicators: If you want to create your custom indicators from scratch, it can be very complex. This often involves programming skills, data analysis, and a deep understanding of market dynamics. Implementing custom indicators may require using platforms like Pine Script for TradingView or coding in languages like Python, JavaScript or C++ for more advanced trading platforms.

In summary, the complexity of technical indicators can range from relatively simple to highly complex. It depends on the specific indicator, your level of expertise, and whether you're using pre-built tools or developing custom solutions. Beginners can start with widely-used indicators and gradually work their way up as they gain experience and knowledge.

While some technical indicators may appear complex and sophisticated, it's essential to understand that complexity alone does not guarantee profitability in trading. The effectiveness of an indicator depends on how well it aligns with your trading strategy, risk management, and your ability to interpret it accurately. Simple indicators, when used skillfully, can be just as profitable as their more intricate counterparts. Ultimately, a trader's success lies not in the complexity of their tools but in their disciplined execution and comprehensive trading plan.

Calculation of Technical Indicators Using OHLC Candlestick Data

Technical indicators are mathematical formulas applied to OHLC candlestick data to derive meaningful insights about price movements. These calculations provide traders with valuable information for making informed trading decisions. Let's break down the process:

Open, High, Low, Close (OHLC): Each candlestick on a price chart represents a specific time period, such as one hour or one day. OHLC data for a candlestick includes:

  • Open: The price at which the period began.
  • High: The highest price reached during the period.
  • Low: The lowest price reached during the period.
  • Close: The price at which the period ended.

Indicator Formula: Each technical indicator has its own unique formula. These formulas are designed to analyze OHLC data and generate a numerical value or a visual representation, such as a line or histogram.

Data Input: The OHLC data for a specified number of periods is used as input for the indicator's formula. For example, if you're calculating a 14-period Relative Strength Index (RSI), you'll use the OHLC data for the most recent 14 candlesticks.

Calculation Steps: The formula processes the OHLC data according to its specific logic. This may involve mathematical operations like averaging, smoothing, or comparing price changes.

Resulting Value: The formula's calculations produce a single value for each period. This value is plotted on the price chart, typically below or alongside the main price plot.

Interpretation: Traders interpret the indicator's values to make trading decisions. For instance, if the indicator crosses a certain threshold or shows divergence with price, it can signal potential buying or selling opportunities.

Examples of popular technical indicators include Moving Averages, Relative Strength Index (RSI), Moving Average Convergence Divergence (MACD), and Bollinger Bands, each with its own unique calculation method. By analyzing these indicators alongside price action, traders gain insights into trends, momentum, volatility, and potential reversal points in the market.

Understanding how technical indicators are calculated based on OHLC data is crucial for traders seeking to harness the power of these tools to enhance their trading strategies and decision-making processes.

Basic Technical Indicators Types

Moving Averages

Moving averages are a fundamental technical indicator that smooths out price data to reveal trends, aiding traders in making informed decisions. The calculation generally involves averaging the price across certain bars. There are different types of moving averages. Some of the popular ones are

  • Simple Moving Average (SMA)
  • Exponential Moving Average (EMA)
  • Weighted Moving Average (WMA)
  • Rolling Moving Average (RMA)
  • Smoothed Moving Average (SMMA)
  • Hull Moving Average (HMA)
  • Double Exponential Moving Average (DEMA)
  • Tripple Exponential Moving Average (TEMA)
  • Volume Weighted Moving Average (VWMA)

  • Zero Lag Exponential Moving Average (ZLEMA)

These are few handful and there are many more variations.


Oscillators occupy a separate overlay than the chart and used for identifying strength of the price movements on a fixed scale. Oscillators can be of two types.

Centered oscillators are technical indicators that oscillate around a central line or point, typically at zero. They provide insights into the speed and magnitude of price movements, helping traders identify overbought and oversold conditions. Some common centered oscillators include the Relative Strength Index (RSI), Moving Average Convergence Divergence (MACD), and the Commodity Channel Index (CCI).

Banded oscillators, on the other hand, fluctuate within predefined upper and lower bands or boundaries. They offer insights into momentum and can signal potential reversals. Common banded oscillators include the Stochastic Oscillator, Relative Vigor Index (RVI), and Williams %R.

Some of the popular Oscillators are:

  • Relative Strength Index (RSI)
  • Stochastic Oscillator
  • Moving Average Convergence Divergence (MACD)
  • Commodity Channel Index (CCI)
