Key Takeaways

  • Anchor signals identify potential reversal points where selling may be exhausted
  • Panic drops with closes in the upper half show buyers stepping in
  • Never buy immediately on a reversal signal - wait for confirmation
  • Use defined risk with stops below signal candle lows

What are Anchor Signals?

Anchor signals identify potential reversal points where selling may be exhausted and buyers could step in. These signals look for extreme moves followed by signs of stabilization.

Falling Knife Warning
Reversal trading is inherently risky - you're betting against the current trend. Never buy on the signal day itself. Wait for at least one confirmation day showing a higher low or higher close before entering. Many apparent bottoms turn into continued declines.

Anchor Signal Types

Anchor Bottom

A candlestick pattern suggesting a potential bottom. The signal looks for:

  • Strong volume (relative volume > threshold)
  • Price at or near 20-day lows
  • Candle body showing buyer interest (small body, long lower shadow)

This pattern resembles traditional hammer/doji patterns but with volume confirmation.

Panic Drop

Detects extreme selling that may be overdone:

  • Large intraday drop (5%+ default)
  • Close in upper portion of the range (buyers stepping in)
  • High volume (capitulation)
Panic Drop Conditions
Change ≤ -drop_threshold% AND Close ≥ (High + Low) / 2

High Octane

Identifies stocks with extreme recent volatility that may be setting up for moves:

  • High ATR relative to price (volatile)
  • Recent large moves (past N days)
  • Volume surge

How to Trade Reversal Signals

Anchor Bottom Strategy

  1. Wait for the anchor signal at a support level
  2. Look for next-day confirmation (higher low, higher close)
  3. Enter on break above the anchor candle's high
  4. Stop below the anchor candle's low

Panic Drop Strategy

  1. Identify the panic drop (large drop, close in upper half)
  2. Research the cause - is it justified or overreaction?
  3. Wait for stabilization (sideways action, volume declining)
  4. Enter on break above panic day's high
Risk Management Best Practices
Reversal trades require strict risk management:
  • Position size: Use smaller positions than normal (50-75%)
  • Stop loss: Always use the signal candle's low as your stop
  • Scaling in: Enter with partial position, add on confirmation
  • R:R ratio: Only take trades with at least 2:1 reward to risk

Risk Management

  • Don't catch falling knives: Wait for confirmation
  • Check fundamentals: Some stocks drop for good reason
  • Position size: Reversals are higher risk - size accordingly
  • Defined risk: Use the signal candle's low as your stop

Tips for Reversal Trading

  • Multi-day confirmation: Best setups confirm over 2-3 days
  • Sector context: Is the whole sector weak or just this stock?
  • Volume profile: Are you buying into prior support levels?
  • Earnings risk: Avoid reversal plays right before earnings
When To Avoid Reversals
Some situations have higher failure rates for reversal signals:
  • Stocks in clear downtrends (lower highs, lower lows)
  • Drops on fundamental news (earnings miss, guidance cut)
  • Sector-wide weakness (not stock-specific)
  • Before major events (earnings, FDA decisions)
