Three Indicators, Zero New Information

Imagine hiring three analysts to evaluate a stock. You hand each of them the exact same five closing prices. The first calculates their simple average. The second calculates how many rupees the price climbed from the first day to the last. The third converts that rupee gain into a percentage.

When all three hand in reports declaring the trend positive, did you receive three independent confirmations? Or did you merely read one factual price move translated through three different arithmetic formulas? Many investors make this exact mistake by crowding their charts with indicators.

The Only Five Ingredients on Any Chart

Every technical indicator relies on the same core data points: Open, High, Low, Close, and Volume (OHLCV). Most popular indicators, including moving averages, the Relative Strength Index (RSI), and MACD, use only closing prices.

Because indicators are mathematical derivatives of past prices, they cannot tell you anything that price itself has not already experienced. When price rises sharply, an average will turn upward, a momentum indicator will register a positive number, and an oscillator will rise toward overbought territory. They are reflections in different mirrors, not separate observers.

A Step-by-Step Math Walkthrough

Consider a hypothetical stock, Company A, tracked over seven consecutive trading sessions. Look at how three different tools derive their values from the exact same closing numbers.

By Day 5, your moving average says the stock trades above its average (₹214 vs ₹206). Your momentum indicator reads +₹14. Your Rate of Change reads +7%. If you place all three on your chart, you feel three times more confident. But all three simply tell you that Day 5 closed higher than Day 1.

The Hazard of Indicator Pile-Ups

In statistics, feeding multiple versions of the same input into a decision model is called multicollinearity. In retail investing, it is called chart clutter. It creates two distinct hazards:

• False Confirmation: Believing you have multiple independent buy or sell signals when you actually have one signal restated multiple times.
• Information Lag: Because calculations require past lookback periods, indicators inherently lag behind direct price action and volume changes.
