RSI (Relative Strength Index)
What it shows: "Overbought" (>70) and "oversold" (<30).
Myth: RSI > 70 = sell. RSI < 30 = buy.
Reality: In a strong trend, RSI can stay overbought for hours while you lose money on "reversals."
Trading Indicators: Truth and Myths
An indicator transforms price or volume data using a chosen lookback. It can standardize an observation; it does not guarantee direction, timing or profit. The useful question is which input it processes and when its rule says SKIP.

Why confirmation appears after price
The Main Problem with Indicators
All indicators are derivatives of price. They show the past, not the future.
- RSI shows that price has ALREADY risen or fallen significantly.
- MACD shows that a trend is ALREADY developing.
- Moving averages show where price WAS.
The problem: when an indicator gives a signal — the move has often already finished.
Indicators don't predict the future. They process the past. This is important to understand.
Popular Indicators: Analysis
| Indicator | Calculation input | Useful for | Limitation | SKIP rule |
|---|---|---|---|---|
| RSI | Average gains vs losses over a lookback | Comparing momentum under fixed settings | Threshold is not a reversal event | Settings or timeframe changed mid-sample |
| MACD | Difference between exponential averages; signal average | Describing trend/momentum alignment | Multiple smoothing stages add delay | Crossover occurs after the planned entry window |
| Bollinger Bands | Moving average plus/minus standard-deviation bands | Describing relative dispersion | Band touch is not a direction forecast | Lookback or deviation is undocumented |
| Stochastic | Close position inside a recent high-low range | Comparing range position | Can remain extreme during a trend | No independent structure/context rule |
MACD
What it shows: Moving average convergence/divergence, trend momentum.
Myth: Line crossover = entry signal.
Reality: Lags. When MACD crosses — the move has often gone halfway already.
Stochastic
What it shows: Price position relative to range over a period.
Myth: Works like RSI — overbought/oversold zones.
Reality: Same problems — gives false reversal signals in trends.
Bollinger Bands
What it shows: Volatility and price deviation from average.
Myth: Price at upper band = sell, at lower = buy.
Reality: In trends, price "rides the band" — counter entries lose money.
Why a claimed "90% indicator strategy" is not evidence
A performance claim needs complete, reproducible data: settings, asset, timestamps, payout, losses, SKIP decisions and out-of-sample results. Without them, stacking indicators does not establish a win rate:
- They all show the same thing. Three price-based indicators won't give three different opinions.
- Lag multiplies. Waiting for all three to align = entering at end of move.
- No context. Indicators don't know about market structure, liquidity, news.
- Curve fitting. Settings optimized for past data don't work in future.
Risk and primary source
An indicator does not guarantee profit. A binary contract can lose the full committed amount when the proposition is false at expiry, and online platforms can introduce separate registration, withdrawal and fraud risks.
How to Use Indicators Correctly
Indicators can be useful if:
1. As a Filter, Not a Signal
Not "RSI < 30 = buy," but "RSI < 30 + bullish structure + order block = consider buying."
2. For Confirmation
You have an idea based on Smart Money. Indicator can confirm: "yes, momentum is in your direction."
3. For Trend Identification
Price above MA 200 = likely bullish market. Rough filter, but it works.
4. One Indicator, Not Five
If using indicators — one. Maximum two. More = chart chaos.
Alternative to Indicators
In Smart Money, instead of indicators we use:
StructureHigher Highs, Lower Lows — clean chart
LiquidityWhere stops are — where price will go
ZonesOrder blocks, FVG — where to enter
ContextWhat's happening on higher TF
This isn't "better" or "worse" than indicators. It's a different approach — based on understanding, not formulas.
