SAR Strategy: The Oversold Bounce Hunter

Nickname: Parabolic Rebound Sniper
Profession: Trend Reversal Sharpshooter
Timeframe: 5 minutes

I. What Is This Strategy?​

Simply put, SAR is:

  • Designed to catch "oversold and about to bounce" opportunities
  • Uses RSI indicator to find oversold points
  • Uses moving averages and Bollinger Bands to confirm position
  • Buy and sell logic are completely symmetrical

It's like a sniper waiting for the target to show its head before firing - doesn't chase highs, doesn't kill lows, specifically ambushes at oversold positions! 🎯

II. Core Configuration: "Quick In, Quick Out"​

Profit-Taking Rules (ROI Table)​

0 minutes  → Run with 4% profit
30 minutes → Run with 2% profit
60 minutes → Run with 1% profit

Translation: Wants 4% right after buying, but after an hour, even 1% profit is okay. Typical "take the money and run" type.

Stop-Loss Rules​

Fixed stop-loss: -10%
Trailing stop: Enabled

Translation: Accept defeat at 10% loss, but if making money, follow the rise, sell when it stops going up.

III. Buy Conditions: 4 Conditions Must All Be Met​

This strategy's buy conditions are strict as airport security - no exceptions:

🎯 Condition #1: RSI Crosses Above 30​

qtpylib.crossed_above(dataframe['rsi'], 30)

Plain English:

"RSI crossed up from below 30, meaning it was oversold and might bounce!"

📉 Condition #2: TEMA Below Bollinger Band Middle Band​

dataframe['tema'] <= dataframe['bb_middleband']

Plain English:

"Price is still at a relatively low position, not buying at the top."

📈 Condition #3: TEMA Rising​

dataframe['tema'] > dataframe['tema'].shift(1)

Plain English:

"Short-term trend is starting to go up, not still falling."

🔊 Condition #4: Has Volume​

dataframe['volume'] > 0

Plain English:

"Don't be a fake signal, someone needs to be trading."

IV. Sell Logic: Completely Symmetrical with Buy​

The beauty of this strategy - buy and sell conditions are symmetrical!

Sell Conditions Are Also 4:​

ConditionBuy VersionSell Version
RSICrosses above 30 (oversold)Crosses above 70 (overbought)
TEMA PositionBelow BB middle bandAbove BB middle band
TEMA TrendRisingFalling
Volume> 0> 0

Plain English:

"Buy is finding oversold bounces, sell is finding overbought pullbacks. Crystal clear logic!"

V. Protection Mechanism: Two "Seatbelts"​

Protection TypeFunctionPlain English
Fixed stop-loss -10%Run if losing too much"Maximum 10% loss, I give up!"
Trailing stopFollow the rise when profitable"Ride it up, sell on the way back down"

Critique: 10% stop-loss is a bit wide, depends on the trading pair's volatility. Some coins have 10% as normal fluctuation, others a 10% drop is a crash 😅

VI. This Strategy's "Personality"​

✅ Pros (Praise Section)​

  1. Symmetrical Logic: Buy and sell conditions perfectly mirror each other, easy to understand and adjust
  2. Classic Method: RSI oversold bounce is textbook-level strategy
  3. Condition Filtering: 4 conditions must all be met, few false signals
  4. Simple Parameters: Not like some strategies with dozens of parameters, this one is easy to tune

⚠️ Cons (Critique Section)​

  1. Gets Slapped Around in Sideways Markets: RSI keeps crossing back and forth, buy and it drops, sell and it rises
  2. Only One Signal Source: No backup plan if this signal doesn't work
  3. Stop-Loss a Bit Wide: 10% might be okay for small coins, but too wide for stablecoins
  4. Doesn't Chase Trends: Misses one-way big rallies because always waiting for oversold

VII. Applicable Scenarios: When to Use It?​

Market EnvironmentRecommendationReason
Oscillating decline reversal✅ Use it!This is its home turf
One-way crash❌ Don't useDon't catch falling knives!
One-way rally❌ Use with cautionIt's waiting for oversold, won't buy in
Sideways oscillation⚠️ Light position testMany false signals, easy to get chopped

VIII. Summary: How's This Strategy Really?​

One-Liner Evaluation​

"Simple and crude oversold bounce hunter, clear logic but not for all markets."

Who Should Use It?​

  • ✅ Beginners learning quantitative trading
  • ✅ Traders who like catching bounces
  • ✅ Steady types who don't chase highs and kill lows
  • ✅ 5-minute timeframe short-term traders

Who Shouldn't Use It?​

  • ❌ Trend-chasing traders
  • ❌ High-frequency traders
  • ❌ People who want to lie flat in sideways markets
  • ❌ People who only want to buy, never sell

My Recommendations​

  1. Test with paper trading first: See how it performs on your chosen trading pairs
  2. Adjust stop-loss: Tune the percentage based on trading pair volatility
  3. Add other indicators: Can add ADX to filter trend strength
  4. Don't use on high-volatility coins: 10% stop-loss might not be enough

IX. What Markets Can This Strategy Make Money In?​

9.1 Core Logic: Oversold Bounce​

SAR strategy is a trend reversal capture strategy. About 250 lines of code, clear and simple logic.

Its Money-Making Philosophy: Extremes Reverse

  • Wait for Oversold: RSI drops below 30, means oversold
  • Wait for Trend Turn: TEMA starts going up, not still falling
  • Wait for Position Confirmation: TEMA still below BB middle band, not buying at top
  • Symmetrical Sell: Overbought then sell, same logic

9.2 Performance in Different Markets (Plain English Version)​

Market TypePerformance RatingPlain English Explanation
📈 Oscillating decline reversal⭐⭐⭐⭐⭐This is its home turf! Catches oversold bounces accurately
🔄 Sideways oscillation⭐⭐⭐☆☆RSI keeps crossing back and forth, gets slapped around
📉 One-way downtrend⭐⭐☆☆☆Don't catch falling knives! Buy more as it drops, lose big
⚡️ High volatility⭐☆☆☆☆Signals can't keep up with price changes

One-Liner Summary: Use SAR for oscillating bounce markets, find another strategy for trend markets!

10.4 Backtesting vs Live Trading​

Backtesting looks great, be careful in live trading!

Recommended Process:

  1. Backtest with historical data first
  2. See if maximum drawdown is acceptable
  3. Run paper trading for a week
  4. Small capital live test
  5. Slowly increase position

Don't go all-in from the start, no matter how good the strategy, it needs to be broken in!

XI. Bonus: The Author's "Little Secrets"​

Looking carefully at the code, you'll find some interesting things:

  1. Strategy named SAR but SAR indicator is just for display

    "I'm called Parabolic SAR, but RSI is actually the main character 😂"

  2. Prepared lots of indicators but only uses a small portion

    "ADX, MACD, MFI, Stochastic all calculated, but buy/sell logic doesn't use them"

  3. Buy and sell conditions are perfectly symmetrical

    "Perfect for OCD! Buy conditions mirror sell conditions"

  4. Commented out lots of candlestick pattern recognition

    "Probably wanted to use candlestick patterns, gave up later"

XII. Final Words​

One-Liner Evaluation​

"Clear logic, beginner-friendly oversold bounce strategy, but choose the right market environment!"

Who Should Use It?​

  • ✅ Quantitative trading beginners
  • ✅ Traders who like catching bounces
  • ✅ 5-minute timeframe short-term players
  • ✅ Steady types who don't chase highs

Who Shouldn't Use It?​

  • ❌ Trend chasers
  • ❌ High-frequency traders
  • ❌ People who want to lie flat
  • ❌ People who only want to make money in bull markets

Manual Trader Recommendations​

If you trade manually, you can reference this logic:

  • Find coins with RSI below 30
  • Wait for the bounce to start (short-term MA going up)
  • Set stop-loss, don't be too greedy
  • Consider selling when RSI reaches around 70

XIII. ⚠️ Risk Emphasis Again (Must Read This Part)​

Backtesting Looks Great, Be Careful in Live Trading​

SAR strategy's historical backtest performance might be pretty good - but note:

Simple strategy doesn't mean stable profit. RSI oversold bounce is a classic method, but there's no holy grail in the market.

Simply put: Good historical performance doesn't guarantee future profits

Hidden Risks in Live Trading​

In live trading, watch out for:

  • Slippage: Buy/sell spread might eat some profits
  • Fees: Frequent trading adds up in fees
  • Liquidity: Small coins might have trouble buying/selling
  • False Breakouts: RSI crossing up then back down is common

My Recommendations (Honest Truth)​

1. Run paper trading for a month first
2. If max drawdown exceeds 20%, adjust parameters
3. Don't use in one-way downtrend markets
4. Adjust stop-loss based on coin volatility

Remember: No matter how good the strategy, when the market teaches you a lesson, it won't give notice. Light position testing, survival is most important! 🙏
