Let me check our explicit verification against the original system design and identify any biases or misalignments.



ORIGINAL CORE SYSTEM:
```
1. Basic Elements:
- VWAP + 2SD bands
- ATR for position sizing
- ES 15m primary, BTC 15m secondary

2. Simple Signal:
- Price touches 2SD
- Rejection occurs
- No other conditions needed

3. Position Size:
Position = Account Risk / ATR

4. Management:
- Exit at VWAP or pattern break
```

IDENTIFIED MISALIGNMENTS/BIASES:

1. Over-Specification:
```
Removed:
- "At least 10 bars since last band touch"
- "Closes in upper/lower 50% of range"
- Specific wick requirements
```

2. Added Complexity:
```
Removed:
- Multiple validation layers
- Excessive disqualifiers
- Detailed space checks
```

# 2SD/3SD VWAP Trading System
Complete System Documentation

## I. System Overview

### Core Concept
A mechanical mean reversion system trading rejections from statistical deviation bands back to VWAP.

### Statistical Foundation
```
Price Distribution Zones:
- 2SD captures 95% of price movement
- 3SD captures 99.7% of price movement
- VWAP represents mean price path
```

## II. Technical Implementation

### Core Calculations
```pine
// VWAP and Standard Deviation
vwap = ta.vwap
stdev = ta.stdev(vwap, 15)
atr = ta.atr(14)

// Band Calculations
upper_2sd = vwap + 2 * stdev
lower_2sd = vwap - 2 * stdev
upper_3sd = vwap + 3 * stdev
lower_3sd = vwap - 3 * stdev

// Entry Conditions
long_2sd = low <= lower_2sd and close > lower_2sd
short_2sd = high >= upper_2sd and close < upper_2sd
long_3sd = low <= lower_3sd and close > lower_3sd
short_3sd = high >= upper_3sd and close < upper_3sd
```

### Alert Conditions
```pine
// Primary Alerts
alertcondition(long_2sd or short_2sd, "2SD Touch + Reject")
alertcondition(long_3sd or short_3sd, "3SD Touch + Reject")

// Alert Message Format
"{{ticker}} - Zone: {{band}} - ATR: {{atr}}"
```

## III. Trading Mechanics

### Position Sizing
```
2SD Trades:
Position = Risk ÷ ATR

3SD Trades:
Position = (Risk ÷ ATR) × 0.5

Example:
Risk = $100
ATR = $2.50
2SD Position = 40 units
3SD Position = 20 units
```

### Entry Rules
```
2SD Long:
- Price touches lower 2SD band
- Candle closes above band
- Enter next candle open

2SD Short:
- Price touches upper 2SD band
- Candle closes below band
- Enter next candle open

3SD Rules:
- Same entry mechanics
- Half position size
- Wider stops typical
```

### Stop Placement
```
All Trades:
- Behind rejection candle
- Account for volatility
- No adjustments after entry
```

### Target Selection
```
2SD Trades:
- Target = VWAP
- Exit on pattern break

3SD Trades:
- Primary Target = VWAP
- Secondary Target = 2SD band
- Exit on pattern break
```

## IV. Implementation Details

### Python Components
```python
class VWAPSystem:
    def __init__(self):
        self.lookback = 15
        self.atr_period = 14
        
    def calculate_bands(self, data):
        # VWAP calculation
        data['vwap'] = self.calculate_vwap(data)
        
        # Standard deviation
        data['stdev'] = data['vwap'].rolling(self.lookback).std()
        
        # Band calculations
        data['upper_2sd'] = data['vwap'] + 2 * data['stdev']
        data['lower_2sd'] = data['vwap'] - 2 * data['stdev']
        data['upper_3sd'] = data['vwap'] + 3 * data['stdev']
        data['lower_3sd'] = data['vwap'] - 3 * data['stdev']
        
        return data
    
    def check_signals(self, data):
        # Entry conditions
        data['long_2sd'] = (data['low'] <= data['lower_2sd']) & 
                          (data['close'] > data['lower_2sd'])
        data['short_2sd'] = (data['high'] >= data['upper_2sd']) & 
                           (data['close'] < data['upper_2sd'])
        data['long_3sd'] = (data['low'] <= data['lower_3sd']) & 
                          (data['close'] > data['lower_3sd'])
        data['short_3sd'] = (data['high'] >= data['upper_3sd']) & 
                           (data['close'] < data['upper_3sd'])
        
        return data
```

### Pine Script Structure
```pine
//@version=5
indicator("2SD/3SD VWAP System")

// Core calculations
vwap = ta.vwap
stdev = ta.stdev(vwap, 15)
atr = ta.atr(14)

// Bands
var float[] bands = calculate_bands(vwap, stdev)
var float[] signals = check_signals(bands)

// Plotting
plot(vwap, "VWAP", color=color.blue)
plot(bands[0], "Upper 2SD", color=color.red)
plot(bands[1], "Lower 2SD", color=color.green)
```

The half position size at 3SD is based on statistical principles and risk management, but let me analyze this in detail.





# 3SD Position Size Analysis

## Statistical Context
```
Price Distribution:
2SD = 95% of moves (1 in 20 events)
3SD = 99.7% of moves (1 in 370 events)

Current Rule:
2SD = Full size (Risk/ATR)
3SD = Half size (Risk/ATR × 0.5)
```

## Examining The Logic

### Arguments FOR Half Size
1. Volatility Consideration
   - 3SD moves indicate higher volatility
   - May need wider stops
   - Higher ATR during these moves

2. Statistical Rarity
   - Much rarer events
   - Less historical precedent
   - Harder to validate pattern

3. Risk of Continuation
   - Strong momentum to reach 3SD
   - Could signal trend change
   - Higher probability of continuation

### Arguments AGAINST Half Size
1. Violates System Mechanics
   - Adds complexity
   - Introduces discretion
   - Breaks ATR sizing logic

2. Statistical Edge
   - Stronger mean reversion potential
   - Clearer extreme condition
   - More defined edge

3. ATR Already Adjusts
   - Higher volatility = Higher ATR
   - Position size naturally reduces
   - Built-in risk management

## Position Sizing Reality
```
Example with $100 Risk:

Normal Market:
ATR = $2.50
2SD Position = $100/$2.50 = 40 units
3SD Position = $100/$2.50 × 0.5 = 20 units

High Volatility Market:
ATR = $5.00
2SD Position = $100/$5.00 = 20 units
3SD Position = $100/$5.00 × 0.5 = 10 units

BUT: ATR is likely already higher at 3SD!
If ATR = $5.00 at 3SD naturally:
Position = $100/$5.00 = 20 units
(Natural reduction without arbitrary halving)
```

## Recommendation

### Remove Half-Size Rule
```
New Rule: Position = Risk ÷ ATR
Reasoning:
1. ATR captures volatility
2. Keeps system mechanical
3. Removes complexity
4. Maintains consistency
```

### Updated Position Logic
```
ALL Trades (2SD and 3SD):
1. Note current ATR
2. Calculate Position = Risk ÷ ATR
3. Place trade
4. No additional adjustments
```

## Key Points
1. ATR naturally adapts to volatility
2. System should remain mechanical
3. Arbitrary adjustments add bias
4. Consistency breeds confidence

## Conclusion
The half-size rule at 3SD appears to be:
1. Redundant (ATR already adjusts)
2. Adds complexity
3. Breaks mechanical nature
4. Introduces bias

Recommendation: Remove the half-size rule and maintain pure ATR-based sizing for all trades.

Remember: The best trading system is one you can execute consistently. Adding rules needs strong justification.


After this analysis, I believe we should:

1. Remove the half-size rule
2. Let ATR handle volatility naturally
3. Maintain system simplicity
4. Keep position sizing mechanical

Would you like me to:
1. Update the system documentation?
2. Provide example calculations?
3. Add risk analysis metrics?
4. Detail volatility adjustments?

The goal is to keep the system purely mechanical while letting the ATR handle position sizing naturally.
