10 Common Indicator Myths, Debunked
The comforting beliefs about indicators that quietly cost traders money.
In short: Most indicator myths share one root error — treating an indicator as a crystal ball rather than a summary of past price — and debunking them means accepting that indicators describe conditions, they do not predict outcomes.
Myth 1 and 2: predictions and secret settings
The first myth is that indicators predict the future. They do not — every one is computed from past data and only describes current conditions. The second is that a secret setting exists that turns an ordinary indicator into a money machine. It does not. Optimising RSI from 14 to 13 will not transform your results; the edge, if any, comes from how you combine tools with risk management and context, not from a magic number nobody else has found.
Myth 3 and 4: more indicators and overbought means sell
The third myth is that more indicators mean more accuracy. In reality most indicators are computed from the same price data, so stacking five oscillators just shows you the same information five times and breeds false confidence. The fourth is that 'overbought' automatically means sell and 'oversold' means buy. In a strong Nifty uptrend, RSI can stay overbought for weeks — overbought is a sign of strength as often as it is a sign of a top.
Myth 5 and 6: crossovers and a single best indicator
The fifth myth is that every crossover is a trade. Moving-average and MACD crossovers whipsaw relentlessly in sideways markets, and trading each one is a fast way to lose. The sixth is that there is one best indicator. There is not; each tool measures one dimension — trend, momentum, volatility or volume — and the 'best' one depends entirely on what you are trying to see and the current market regime.
Myth 7 and 8: indicators over price and complexity
The seventh myth is that indicators are more important than price itself. They are derived from price, so price action is the primary information and indicators are a lens on it, never a replacement. The eighth is that a more complex indicator is a better one. Complexity usually means more parameters to overfit and more ways to be fooled; many professionals rely on a handful of simple, well-understood tools rather than elaborate custom ones.
Myth 9 and 10: backtests and indicators alone
The ninth myth is that a great backtest guarantees future profit. Curve-fitted or repainting backtests routinely look perfect and fail live, so a backtest is a sanity check, not a promise. The tenth is that indicators alone are a complete trading system. They are not — without position sizing, stop placement and risk rules, even a good signal set will not produce consistent results. Indicators inform decisions; they do not make them for you.
The common thread
Every one of these myths comes from the same wish: for certainty in a market that offers none. Indicators are genuinely useful — they organise information, flag conditions and enforce discipline — but only when treated honestly, as descriptive summaries of past price and volume. The traders who last are the ones who dropped the search for a magic tool and instead learned to read a few indicators well, in context, alongside price and risk management.
Key takeaways
- Indicators describe past conditions; they do not predict the future.
- There is no secret setting and no single best indicator.
- More indicators usually means the same information repeated, not more accuracy.
- Overbought and crossovers are context-dependent, not automatic signals.
- Indicators are a lens on price and are useless without risk management.
