About Open Indicator Lab

Open Indicator Lab exists to document how commonly used trading indicators actually work. Over time, many standard technical ideas — moving averages, momentum oscillators, volatility measures — have been repackaged, branded, and marketed as proprietary systems. While tools are often explained at a surface level, the underlying mechanics are rarely discussed in detail. This site focuses on what’s under the hood.

What We Believe

  • Traders should understand the tools they use
  • Basic technical concepts shouldn’t require expensive subscriptions
  • Clarity is more useful than complexity
  • Education matters more than presentation

What This Site Does

  • Explains what an indicator actually measures
  • Describes how it’s constructed at a conceptual level
  • Shows when it tends to help
  • Highlights where it tends to fail
  • Explains how traders commonly recreate similar behavior manually

Common Misconceptions

“Proprietary” means unique or complex.

Often it just means a familiar technical idea packaged into a specific visual layout or preset. Closed-source does not automatically mean fundamentally different.

More complexity means more edge.

Extra inputs and conditions can make a tool harder to understand and harder to use consistently. Simpler tools can be strong because they’re easier to reason about.

Institutions use entirely different indicators.

Institutions may have different data and execution, but many concepts — trend, momentum, volatility — are the same. Process and context matter more than “secret indicators.”

Paying for a tool guarantees better results.

Buying an indicator can feel like progress, but ownership doesn’t create understanding. Without knowing what it measures and when it fails, price doesn’t help.

Indicators are meant to give signals.

Most tools are best used as context filters — trend bias, momentum conditions, volatility regime — not as stand-alone buy/sell systems.

If it’s popular, it must be superior.

Popularity often reflects marketing reach and presentation. Understanding how the indicator works matters more than how widely it’s promoted.


Open Indicator Lab is not a signal service, a paid course, or a promise of profitability.

We don’t provide alerts, trade calls, or shortcuts.

The goal is to document how indicators work — not to tell anyone when to trade.

If an indicator can’t be explained down to its underlying mechanics, it probably isn’t understood well enough to trade.
