đ Key Criteria
Double-bottom pattern (W-shaped price action)
Price touching or below lower Bollinger Band (oversold condition)
RSI < 30 (oversold momentum)
Ideal buy zone: when both BolÂlinger and RSI oversold align with the second dip of the W-pattern.
đ ď¸ Tools & Setup
1. TradingView Scanning + Indicators
Apply a pattern-finder script like âDouble Bottom Finderâ or âPatternsmart Autoâ to automatically mark W-patterns.
Overlay Bollinger Bands and the RSI (14) on the chart.
Any timestamp where:
The doubleâbottom apex (second low) occurs
Price touches or drops below the lower Bollinger Band
RSI is under 30
âŚis your target buy zone.
2. Alerts Setup
Double-Bottom Alert: Set an alert for the pattern script.
Oversold Alerts:
âRSI crossing below 30â
âPrice touching the lower Bollinger bandâ
Combine or manually review charts where both alerts coincide.
Many Pine scripts support multi-condition alertsâyou can create one that triggers only when both conditions happen together.
3. Use Crypto Screeners
TradingView Crypto Screener:
Filter by RSI < 30
Check each coin chart for Bollinger oversold + W-pattern
Advanced scanners (e.g. LuxAlgo, TrendSpider) can auto-flag W-patterns and allow custom filters like RSI and Bollinger.
4. Timeframes & Watchlist
Focus on 4H and Daily charts for reliable setups
Build a watchlist: BTC, ETH, BNB, SOL, ADA, AVAX, MATIC, etc.
Manually scan or set alerts per coin in scope.
đŻ Sample Setup Workflow
Open TradingView
Create a layout with 4â6 cryptos (e.g., BTCUSDT, ETHUSDT, SOLUSDTâŚ)
Add:
Double-bottom detection script
Bollinger Bands (20,2)
RSI (14)
Set alerts:
Pattern appears
RSI drops below 30
Price touches lower BB
Monitor: When both oversold alerts + pattern coincide, mark that candle as a potential buy zone
