RSI (Relative Strength Index)

MACD
Components:
- MACD line (12 EMA - 26 EMA)
- Signal line (9 EMA of MACD)
- Histogram (MACD - Signal)
Signals:
- Crossovers: Entry/exit
- Histogram: Momentum
- Divergences: Reversals
Best Use: Trend confirmation and momentum
Bollinger Bands
Components:
- Middle band: 20 SMA
- Upper band: +2 standard deviations
- Lower band: -2 standard deviations
Interpretation:
- Price at upper band: Potentially overbought
- Price at lower band: Potentially oversold
- Band squeeze: Low volatility, breakout pending
Best Use: Volatility analysis and mean reversion
Volume
What to Watch:
- Volume confirms price moves
- High volume = strong moves
- Low volume = weak moves
Patterns:
- Volume spikes
- Volume drying up
- Accumulation/distribution
Best Use: Confirming breakouts and moves
ATR (Average True Range)
What It Shows: Average price range over period
Uses:
- Stop loss placement
- Position sizing
- Volatility assessment
Application:
- 2 ATR stop loss
- Size position based on ATR
Indicator Combinations
Trend + Momentum
Example: Moving Average + RSI
Logic: MA shows trend, RSI shows if overbought/oversold within trend
Multiple Timeframes
Example: Daily trend, hourly entry
Logic: Higher timeframe trend, lower timeframe timing
Classic Setup
Components:
- 20/50 EMA for trend
- RSI for momentum
- Volume for confirmation
Using Indicators Effectively
Don't Over-Complicate
Mistake: Too many indicators cause confusion
Better: 2-3 indicators from different categories
Understand What Each Shows
Important: Know what indicator measures before using
Combine with Price Action
Best Practice:
- Indicators support price action
- Price action is primary
- Indicators are secondary
Context Matters
Consider:
- Timeframe
- Market conditions
- Stock characteristics
Indicator Signals
Confirmation Signals
Worth a closer look when: multiple indicators agree — though agreement narrows the shortlist rather than raising the hit rate. Tested on FX majors, agreement between three indicators moved it from 49.1% to 49.6%, against 51.3% for taking no signal at all.
Example: Price breaks resistance + RSI breaks 50 + Volume increases
Divergence Signals
Definition: Price and indicator move differently
Bullish Divergence: Price makes lower low, RSI makes higher low
Bearish Divergence: Price makes higher high, RSI makes lower high
Crossover Signals
Types:
- MA crossovers
- MACD crossovers
- Stochastic crossovers
Indicator Limitations
Lagging Nature
Reality: Most indicators lag price
Implication: Confirmation, not prediction
False Signals
Reality: Indicators give wrong signals
Solution: Use multiple confirmations
Over-Optimization
Problem: Perfect settings for past don't work in future
Solution: Use standard settings
Market Conditions
Issue: Indicators work better in some conditions
Example: Oscillators work better in ranges
Indicator Settings
Standard vs Custom
Recommendation: Start with standard settings
Why:
- Widely used
- Self-fulfilling
- Tested
Timeframe Adjustment
Consider:
- Shorter timeframe: Faster settings
- Longer timeframe: Standard or slower
