Egg vs Tennis Ball — Drop/Rebound Strength

Egg vs Tennis Ball — Drop/Rebound Meter

What it does
Classifies selloffs as either:

• []Eggs — dead‑cat, no bounce
  []Tennis Balls — fast, decisive rebound
  

Core features

• []Detects swing drops from a Pivot High (PH) to a Pivot Low (PL)
  []Requires drops to be meaningful (volatility‑aware, ATR‑scaled)
  []Draws a bounce threshold line and a deadline
  []Decides outcome based on speed and extent of rebound
  []Tracks scores and win rates across multiple lookback windows
  []Includes a color‑coded meter and current streak display
  

Visuals at a glance

• []Gray diagonal — drop from PH to PL
  []Teal dotted horizontal — bounce threshold, from PH to the deadline
  []Solid green — Tennis Ball (bounce line broken before the deadline)
  []Solid red — Egg (deadline expired before the bounce)
  
• Optional PH / PL labels for clarity
  

How the decision is made

• []1) Find pivots — symmetric pivots using Pivot Left / Right; PL confirms after Right bars.
  []2) Qualify the drop — Drop Size = PH − PL; must be ≥ (Drop Threshold × ATR at PL).
  []3) Define the bounce line — PL + (Bounce Multiple × Drop Size). 1.00× = full retrace to PH; up to 2.00× for overshoot.
  []4) Set the deadline — Drop Bars = PL index − PH index; Deadline = Drop Bars × Recovery Factor; timer starts from PH or PL.
  
• 5) Resolve — Tennis Ball if price hits the bounce line before the deadline; Egg if the deadline passes first.
  

Scoring system (−100 to +100)

• []+100 = perfect Tennis Ball (fastest possible + full overshoot)
  []−100 = perfect Egg (no recovery)
  
• In between: scored by rebound speed and extent, shaped by your weight settings
  

Meter Table
Columns (toggle on/off)

• []All (off by default)
  []Last N1 (default 5)
  []Last N2 (default 10)
  []Last N3 (default 20)
  

Rows

• []Tennis / Eggs — counts
  []% Tennis — win rate
  []Avg Score — normalized quality from −100 to +100
  []Streak — overall (not windowed), e.g., +3 = 3 Tennis Balls in a row, −4 = 4 Eggs in a row
  

Alerts

• []Tennis Ball – Fast Rebound — triggers when the bounce line is broken in time
  []Egg – Window Expired — triggers when the deadline passes without a bounce
  

Inputs

① Drop Detection

• []Pivot Left / Right
  []ATR Length
  
• Drop Threshold × ATR
  

② Bounce Requirement

• Bounce Multiple × Drop Size (0.10–2.00×)
  

③ Timing

• []Timer Start — PH or PL
  []Recovery Factor × Drop Bars
  
• Break Trigger — Close or High
  

④ Display

• []Show Pivot/Outcome Labels
  []Line Width
  
• Table Position (corner)
  

⑤ Meter Columns

• []Show All (off by default)
  []Show N1 / N2 / N3 (5, 10, 20 by default)
  

⑥ Scoring Weights

• []Tennis — Base, Speed, Extent
  []Egg — Base, Strength
  

How to use it

• []Pick strictness — start with Drop Threshold = 2.0 ATR, Bounce Multiple = 1.0×, Recovery Factor = 3.0×; adjust to timeframe and volatility.
  []Watch the dotted line — it ends at the deadline; turns solid green (Tennis) if broken in time, solid red (Egg) if it expires.
  []Read the meter — short windows (5–10) show current behavior; Avg Score captures quality; Streak shows momentum.
  []Blend with your system — combine with trend filters, volume, or regime detection.
  

Tips

• []Close vs High trigger: Close is stricter; High is more responsive.
  []PH vs PL timer start: PH measures round‑trip; PL measures recovery only.
  []Increase pivot strength for fewer, more reliable signals.
  []Higher timeframes generally produce cleaner patterns.
  

Defaults

• []Pivot L/R: 5 / 5
  []ATR Length: 14
  []Drop Threshold: 2.0× ATR
  []Bounce Multiple: 1.00×
  []Recovery Factor: 3.0×
  []Break Trigger: Close
  
• Windows: Last 5, 10, 20 (All off)
  

Interpreting results

• []Tennis‑y: Avg Score +30 to +70, %Tennis > 55%
  []Mixed: Avg Score near 0
  
• Egg‑y: Avg Score −30 to −80, %Tennis < 45%
