Every beginner's charting platform looks the same: a price chart buried under eight indicators, all flashing different colours, all supposedly revealing hidden market secrets. Here's the uncomfortable truth — the vast majority of those tools are just price fed into a formula and spat back out. They are not independent signals. They are echoes.

Take the RSI. It measures the ratio of average up-closes to average down-closes over 14 periods by default. The MACD subtracts a 26-period EMA from a 12-period EMA, then plots a 9-period signal line on top. Bollinger Bands wrap a 20-period simple moving average in a two-standard-deviation envelope. Every single one starts with the same raw ingredient: price.

CONCEPTIndicators summarise price history — they confirm what price already did, not what it will do next.
WARNINGStacking multiple indicators built from the same price data creates the illusion of confirmation, not actual confirmation.
KEY IDEAVolume and market breadth are among the few inputs that are genuinely independent of price — use them accordingly.

This matters because traders routinely stack RSI plus MACD plus Stochastic and call it a "triple confirmation" system. It is not. All three are derived from price closes, so when they agree, they are mostly agreeing with each other. Statisticians call this multicollinearity. Traders just call it Wednesday when the trade blows up despite three green lights.

Indicator Inputs: Price vs Independent Data % Input from Price RSI 100% MACD 100% BB 100% OBV 40% Breadth 20% Pure price derivative Partial Mostly independent

The practical fix is to pair price-based indicators with genuinely independent data. On-Balance Volume incorporates tick volume, which price alone does not capture. Market breadth measures how many instruments are advancing versus declining — again, separate information. Traders who understand this distinction can find more thorough explanations through resources like price derivatives on Investopedia, the RSI breakdown on Wikipedia, and Investopedia's detailed write-up on multicollinearity in financial models.

Use fewer indicators, understand what each one actually measures, and make sure they are not all measuring the same thing in a different suit.
