Key Technical Indicators: What Works and What Doesn't

The Honest Truth About Indicators

Most technical indicators are derived from price and/or volume. They don't predict anything independently — they're different mathematical transformations of data you already have.

Used correctly, indicators confirm what price structure suggests. Used as standalone predictors, they create false confidence and excessive trade signals.

The right relationship with indicators:

1. 1Price structure (trend, support/resistance) is primary
2. 2Candlestick patterns are your entry trigger
3. 3Indicators confirm the trade thesis, they don't create it

With that framing, here are the indicators worth knowing:

Moving Averages

Moving averages smooth price action, making trends easier to identify.

Simple Moving Average (SMA)

Calculates the average closing price over N periods, giving equal weight to all periods.

Key SMAs:

• 20 SMA: Short-term trend reference
• 50 SMA: Medium-term; major institutional reference
• 200 SMA: Long-term trend; most-watched by large funds

Usage:

• Crossovers: 20 SMA crossing above 50 SMA = short-term momentum turning bullish
• Price location: Above 200 SMA = long-term uptrend; below = downtrend
• Dynamic support/resistance: Price often bounces from key SMAs in strong trends

Exponential Moving Average (EMA)

Same as SMA but with more weight on recent prices. Reacts faster to recent price changes.

EMAs are preferred for shorter-term trading; SMAs are often used for longer-term trend analysis.

Common use cases:

• 9 EMA: Very short-term; popular for scalpers
• 21 EMA: Short-term trend on day trading timeframes
• 50 EMA / 200 EMA: Institutional references

RSI (Relative Strength Index)

RSI measures the speed and magnitude of recent price changes, oscillating between 0 and 100.

Standard settings: 14 periods

Interpretation:

• Above 70: Overbought (price has moved up fast; potential for pullback)
• Below 30: Oversold (price has moved down fast; potential for bounce)
• Above 50: Generally bullish momentum
• Below 50: Generally bearish momentum

Critical caveat: In strong trends, RSI can stay overbought (70–90) for extended periods without reversing. Don't short just because RSI is above 70.

Most useful RSI application: Divergence

Bullish divergence: Price makes a new lower low, but RSI makes a higher low. This indicates selling momentum is weakening — potential reversal.

Bearish divergence: Price makes a new higher high, but RSI makes a lower high. Buying momentum is weakening.

Divergence is a leading indicator when used at key levels; it's unreliable without structural context.

MACD (Moving Average Convergence Divergence)

MACD measures the difference between two EMAs (typically 12-period and 26-period) and plots the result against a 9-period signal line.

Components:

• MACD line: 12 EMA minus 26 EMA
• Signal line: 9 EMA of the MACD line
• Histogram: MACD minus Signal; shows momentum direction and strength

Common uses:

• MACD crossover: MACD crossing above the signal line = bullish; below = bearish
• Zero line crossover: MACD crossing above zero = medium-term momentum turned bullish
• Histogram: Expanding histogram = increasing momentum; shrinking = momentum declining

MACD is a lagging indicator — it confirms trends that are already underway. It's best used for trend direction confirmation, not predicting reversals.

Volume Indicators

OBV (On-Balance Volume)

OBV adds volume on up days and subtracts it on down days, creating a cumulative line.

Usage: When OBV is rising while price is flat or rising, buying is stronger than price suggests — bullish. When OBV diverges from price (OBV falling while price rises), distribution may be occurring.

VWAP (Volume-Weighted Average Price)

VWAP calculates the average price weighted by volume for the day. Used extensively by institutional traders as a reference benchmark.

Usage:

• Institutions buy below VWAP, sell above: Price above VWAP is "expensive," below is "cheap" on an intraday basis
• VWAP acts as intraday support and resistance
• Many day trading strategies (like the VWAP Reclaim) are built around VWAP as a central reference

VWAP resets daily and is most useful on intraday timeframes (1-minute to 15-minute).

What to Avoid: Indicator Overload

Adding 5–7 indicators to a chart does not improve analysis. It creates noise, contradictions, and analysis paralysis.

The maximum indicator principle: Most professional traders use 2–3 indicators at most. Some use none at all, trading pure price action.

Recommended starting setup:

• Price structure (no indicator needed)
• One moving average (20 or 50 EMA as dynamic support/resistance)
• RSI (for divergence and momentum context)
• Volume (for confirmation)

That's four elements. Add MACD or VWAP if your strategy specifically requires them. Stop there.

Exercise: Remove all indicators from your primary trading chart. Trade using only price structure, support/resistance, and candlestick patterns for one week. Then add back your one most-used indicator and compare. This exercise reveals which indicators actually improve your analysis vs. which are creating noise.
