RSI Trading Strategies
Strategy 1: Overbought/Oversold
Concept: Buy when oversold, sell when overbought.
Long Entry:
- RSI drops below 30
- RSI rises back above 30
- Enter LONG
- SL below recent low
- TP at 50-70 RSI zone or resistance
Short Entry:
- RSI rises above 70
- RSI drops back below 70
- Enter SHORT
- SL above recent high
- TP at 30-50 RSI zone or support
Example FCPO:
Price: 4,150 (at support)
RSI: 25 (oversold)
RSI bounces from 25 to 32 → Entry LONG
Target: RSI reaches 50-60 zone
Strategy 2: RSI Divergence
Bullish Divergence:
- Price makes LOWER low
- RSI makes HIGHER low
- Signal: Potential bullish reversal
Price: \ /\
\ / \
\/ ← Lower low
RSI: \ /\
\__/ ← Higher low (divergence!)
Bearish Divergence:
- Price makes HIGHER high
- RSI makes LOWER high
- Signal: Potential bearish reversal
Price: /\
/ \ /\
\/ ← Higher high
RSI: /\
/ \__ ← Lower high (divergence!)
Trading Divergence:
- Identify divergence
- Wait for price confirmation (break of trendline/support/resistance)
- Entry on confirmation
- SL beyond divergence extreme
- Target previous swing high/low
Strategy 3: RSI Trendline Break
Concept: Draw trendlines on RSI itself.
Bullish Setup:
- RSI in downtrend (making lower lows)
- Draw downtrend line on RSI
- RSI breaks above trendline
- Entry LONG
Bearish Setup:
- RSI in uptrend (making higher highs)
- Draw uptrend line on RSI
- RSI breaks below trendline
- Entry SHORT
Strategy 4: RSI 50 Crossover
Concept: RSI 50 acts as momentum filter.
Long Signal:
- RSI crosses above 50
- Confirms bullish momentum
- Look for long entries
Short Signal:
- RSI crosses below 50
- Confirms bearish momentum
- Look for short entries
Use as filter:
- Only take longs when RSI > 50
- Only take shorts when RSI < 50

RSI Pada Multiple Timeframes
Multi-TF Analysis
- Higher TF (4H/Daily): Determine overall momentum
- Trading TF (1H/15min): Find entry signals
Example:
Daily RSI: 65 (bullish momentum, not overbought)
1H RSI: 28 (oversold)
Interpretation:
- Daily says overall bullish
- 1H says short-term oversold
- Action: Look for LONG entry on 1H
Alignment Principle
Strong signal:
- All timeframes agree (all bullish or all bearish)
Weak signal:
- Timeframes conflict (mixed signals)
Common RSI Mistakes
Mistake 1: Trading Overbought/Oversold Blindly
Salah: RSI > 70 = Immediately sell Betul: RSI > 70 = Wait for confirmation (RSI turning down, price rejection)
Why:
- In strong trends, RSI can stay overbought/oversold for LONG time
- "Overbought can get more overbought"
Mistake 2: Ignoring Trend
In Strong Uptrend:
- RSI stays 40-80 range
- 40-50 is "oversold" in this context
- Buying at 70 can work!
In Strong Downtrend:
- RSI stays 20-60 range
- 50-60 is "overbought" in this context
- Selling at 30 can work!
Mistake 3: Using RSI Alone
Salah: Only look at RSI Betul: RSI + Price Action + S/R levels
RSI is CONFIRMATION, not primary signal.
Mistake 4: Wrong Period for Timeframe
Salah: 14 RSI on 1-minute chart (too choppy) Betul: Match RSI period to trading timeframe
RSI With Other Tools
RSI + Support/Resistance
Best combo:
- Price at support + RSI oversold = Strong buy signal
- Price at resistance + RSI overbought = Strong sell signal
Example:
Support: 4,180
Price: 4,182 (at support)
RSI: 28 (oversold)
Confluence! Strong long signal.
RSI + Candlestick Patterns
Enhanced entry:
- RSI oversold + Hammer at support = Very strong long signal
- RSI overbought + Shooting star at resistance = Very strong short signal
RSI + Moving Averages
Trend filter:
- Price > 50 EMA + RSI > 50 = Bullish environment
- Price < 50 EMA + RSI < 50 = Bearish environment
RSI Entry Checklist
Before entry based on RSI:
- RSI at extreme (< 30 or > 70)?
- Price at key level (S/R)?
- Candlestick confirmation?
- Trend alignment?
- RSI turning (not just touching extreme)?
If all checked: Higher probability trade
