# Continuous Data Training Strategy
## Overview
The ANNOTATE system trains models on **continuous OHLCV data** from the database, not just on annotated signals. This teaches the model **when to act AND when NOT to act**.
## Training Data Composition
For each annotation, the system creates multiple training samples:
### 1. ENTRY Sample (1 per annotation)
- **Label**: `ENTRY`
- **Action**: `BUY` or `SELL`
- **Purpose**: Teach model to recognize entry signals
- **Repetitions**: 100x (configurable)
```python
{
'label': 'ENTRY',
'action': 'BUY',
'direction': 'LONG',
'timestamp': '2025-10-27 14:00',
'entry_price': 2500.0,
'repetitions': 100
}
```
### 2. HOLD Samples (N per annotation)
- **Label**: `HOLD`
- **Action**: `HOLD`
- **Purpose**: Teach model to maintain position
- **Count**: Every candle between entry and exit
- **Repetitions**: 25x (1/4 of entry reps)
```python
# For a 30-minute trade with 1m candles = 30 HOLD samples
{
'label': 'HOLD',
'action': 'HOLD',
'in_position': True,
'timestamp': '2025-10-27 14:05', # During position
'repetitions': 25
}
```
### 3. EXIT Sample (1 per annotation)
- **Label**: `EXIT`
- **Action**: `CLOSE`
- **Purpose**: Teach model to recognize exit signals
- **Repetitions**: 100x
```python
{
'label': 'EXIT',
'action': 'CLOSE',
'timestamp': '2025-10-27 14:30',
'exit_price': 2562.5,
'profit_loss_pct': 2.5,
'repetitions': 100
}
```
### 4. NO_TRADE Samples (±15 candles per annotation)
- **Label**: `NO_TRADE`
- **Action**: `HOLD`
- **Purpose**: Teach model when NOT to trade
- **Count**: Up to 30 samples (15 before + 15 after signal)
- **Repetitions**: 50x (1/2 of entry reps)
```python
# 15 candles BEFORE entry signal
{
'label': 'NO_TRADE',
'action': 'HOLD',
'timestamp': '2025-10-27 13:45', # 15 min before entry
'direction': 'NONE',
'repetitions': 50
}
# 15 candles AFTER entry signal
{
'label': 'NO_TRADE',
'action': 'HOLD',
'timestamp': '2025-10-27 14:15', # 15 min after entry
'direction': 'NONE',
'repetitions': 50
}
```
## Data Fetching Strategy
### Extended Time Window
To support negative sampling (±15 candles), the system fetches an **extended time window**:
```python
# Configuration
context_window_minutes = 5 # Base context
negative_samples_window = 15 # ±15 candles
extended_window = max(5, 15 + 10) # = 25 minutes
# Time range
start_time = entry_timestamp - 25 minutes
end_time = entry_timestamp + 25 minutes
```
### Candle Limits by Timeframe
```python
# 1s timeframe: 25 min × 60 sec × 2 + buffer = ~3100 candles
# 1m timeframe: 25 min × 2 + buffer = ~100 candles
# 1h timeframe: 200 candles (fixed)
# 1d timeframe: 200 candles (fixed)
```
## Training Sample Distribution
### Example: Single Annotation
```
Annotation: LONG entry at 14:00, exit at 14:30 (30 min hold)
Training Samples Created:
├── 1 ENTRY sample @ 14:00 (×100 reps) = 100 batches
├── 30 HOLD samples @ 14:01-14:29 (×25 reps) = 750 batches
├── 1 EXIT sample @ 14:30 (×100 reps) = 100 batches
└── 30 NO_TRADE samples @ 13:45-13:59 & 14:01-14:15 (×50 reps) = 1500 batches
Total: 62 unique samples → 2,450 training batches
```
### Example: 5 Annotations
```
5 annotations with similar structure:
Training Samples:
├── ENTRY: 5 samples (×100 reps) = 500 batches
├── HOLD: ~150 samples (×25 reps) = 3,750 batches
├── EXIT: 5 samples (×100 reps) = 500 batches
└── NO_TRADE: ~150 samples (×50 reps) = 7,500 batches
Total: ~310 unique samples → 12,250 training batches
Ratio: 1:30 (entry:no_trade) - teaches model to be selective!
```
## Why This Works
### 1. Reduces False Positives
By training on NO_TRADE samples around signals, the model learns:
- Not every price movement is a signal
- Context matters (what happened before/after)
- Patience is important (wait for the right moment)
### 2. Improves Timing
By training on continuous data, the model learns:
- Gradual buildup to entry signals
- How market conditions evolve
- Difference between "almost" and "ready"
### 3. Teaches Position Management
By training on HOLD samples, the model learns:
- When to stay in position
- Not to exit early
- How to ride trends
### 4. Balanced Training
The repetition strategy ensures balanced learning:
- ENTRY: 100 reps (high importance)
- EXIT: 100 reps (high importance)
- NO_TRADE: 50 reps (moderate importance)
- HOLD: 25 reps (lower importance, but many samples)
## Database Requirements
### Continuous OHLCV Storage
The system requires **continuous historical data** in DuckDB:
```sql
-- Example: Check data availability
SELECT
symbol,
timeframe,
COUNT(*) as candle_count,
MIN(timestamp) as first_candle,
MAX(timestamp) as last_candle
FROM ohlcv_data
WHERE symbol = 'ETH/USDT'
GROUP BY symbol, timeframe;
```
### Data Gaps
If there are gaps in the data:
- Negative samples will be fewer (< 30)
- Model still trains but with less context
- Warning logged: "Could not create full negative sample set"
## Configuration
### Adjustable Parameters
```python
# In _prepare_training_data()
negative_samples_window = 15 # ±15 candles (default)
training_repetitions = 100 # 100x per sample (default)
# Derived repetitions
hold_repetitions = 100 // 4 # 25x
no_trade_repetitions = 100 // 2 # 50x
```
### Tuning Guidelines
| Parameter | Small Dataset | Large Dataset | High Precision |
|-----------|--------------|---------------|----------------|
| `negative_samples_window` | 10 | 20 | 15 |
| `training_repetitions` | 50 | 200 | 100 |
| `extended_window_minutes` | 15 | 30 | 25 |
## Monitoring
### Training Logs
Look for these log messages:
```
✅ Good:
"Fetching HISTORICAL market state for ETH/USDT at 2025-10-27 14:00"
"Extended window: ±25 minutes (Includes ±15 candles for negative sampling)"
"1m: 100 candles from DuckDB (historical)"
"Added 30 NO_TRADE samples (±15 candles)"
"→ 15 before signal, 15 after signal"
⚠️ Warning:
"No historical data found, using latest data as fallback"
"Could not create full negative sample set (only 8 samples)"
"Market data has 50 timestamps from ... to ..." (insufficient data)
```
### Sample Distribution
Check the final distribution:
```
INFO - Prepared 310 training samples from 5 test cases
INFO - ENTRY samples: 5
INFO - HOLD samples: 150
INFO - EXIT samples: 5
INFO - NO_TRADE samples: 150
INFO - Ratio: 1:30.0 (entry:no_trade)
```
**Ideal Ratio**: 1:20 to 1:40 (entry:no_trade)
- Too low (< 1:10): Model may overtrade
- Too high (> 1:50): Model may undertrade
## Benefits
### 1. Realistic Training
- Trains on actual market conditions
- Includes noise and false signals
- Learns from continuous price action
### 2. Better Generalization
- Not just memorizing entry points
- Understands context and timing
- Reduces overfitting
### 3. Selective Trading
- High ratio of NO_TRADE samples
- Learns to wait for quality setups
- Reduces false signals in production
### 4. Efficient Use of Data
- One annotation → 60+ training samples
- Leverages continuous database storage
- No manual labeling of negative samples

# Final Data Structure Implementation Summary
## What Was Implemented
### ✅ 5 Batches of 600 Candles Each
**Primary Symbol** (e.g., ETH/USDT):
- 1s timeframe: 600 candles (10 minutes of data)
- 1m timeframe: 600 candles (10 hours of data)
- 1h timeframe: 600 candles (25 days of data)
- 1d timeframe: 600 candles (~1.6 years of data)
**Secondary Symbol** (BTC/USDT or ETH/USDT):
- 1m timeframe: 600 candles (10 hours of data)
**Total**: 3,000 candles per annotation
---
## Symbol Pairing Logic
```python
def _get_secondary_symbol(primary_symbol):
"""
ETH/USDT → BTC/USDT
SOL/USDT → BTC/USDT
BTC/USDT → ETH/USDT
"""
if 'BTC' in primary_symbol:
return 'ETH/USDT'
else:
return 'BTC/USDT'
```
---
## Data Structure
```python
market_state = {
'symbol': 'ETH/USDT',
'timestamp': '2025-10-27 14:00:00',
# Primary symbol: 4 timeframes × 600 candles
'timeframes': {
'1s': {'timestamps': [...], 'open': [...], 'high': [...], 'low': [...], 'close': [...], 'volume': [...]},
'1m': {'timestamps': [...], 'open': [...], 'high': [...], 'low': [...], 'close': [...], 'volume': [...]},
'1h': {'timestamps': [...], 'open': [...], 'high': [...], 'low': [...], 'close': [...], 'volume': [...]},
'1d': {'timestamps': [...], 'open': [...], 'high': [...], 'low': [...], 'close': [...], 'volume': [...]}
},
'secondary_symbol': 'BTC/USDT',
# Secondary symbol: 1 timeframe × 600 candles
'secondary_timeframes': {
'1m': {'timestamps': [...], 'open': [...], 'high': [...], 'low': [...], 'close': [...], 'volume': [...]}
}
}
```

# Training Improvements Summary
## What Changed
### 1. Extended Data Fetching Window ✅
**Before:**
```python
context_window = 5 # Only ±5 minutes
start_time = timestamp - 5 minutes
end_time = timestamp + 5 minutes
```
**After:**
```python
context_window = 5
negative_samples_window = 15 # ±15 candles
extended_window = max(5, 15 + 10) # = 25 minutes
start_time = timestamp - 25 minutes
end_time = timestamp + 25 minutes
```
**Impact**: Fetches enough data to create ±15 candle negative samples
---
### 2. Dynamic Candle Limits ✅
**Before:**
```python
limit = 200 # Fixed for all timeframes
```
**After:**
```python
if timeframe == '1s':
limit = extended_window_minutes * 60 * 2 + 100 # ~3100
elif timeframe == '1m':
limit = extended_window_minutes * 2 + 50 # ~100
elif timeframe == '1h':
limit = max(200, extended_window_minutes // 30) # 200+
elif timeframe == '1d':
limit = 200
```
**Impact**: Requests appropriate amount of data per timeframe
---
### 3. Improved Logging ✅
**Before:**
```
DEBUG - Added 30 negative samples
```
**After:**
```
INFO - Test case 1: ENTRY sample - LONG @ 2500.0
INFO - Test case 1: Added 30 HOLD samples (during position)
INFO - Test case 1: EXIT sample @ 2562.5 (2.50%)
INFO - Test case 1: Added 30 NO_TRADE samples (±15 candles)
INFO - → 15 before signal, 15 after signal
```
**Impact**: Clear visibility into training data composition
---
### 4. Historical Data Priority ✅
**Before:**
```python
df = data_provider.get_historical_data(limit=100) # Latest data
```
**After:**
```python
# Try DuckDB first (historical at specific timestamp)
df = duckdb_storage.get_ohlcv_data(
start_time=start_time,
end_time=end_time
)
# Fallback to replay
if df is None:
df = data_provider.get_historical_data_replay(
start_time=start_time,
end_time=end_time
)
# Last resort: latest data (with warning)
if df is None:
logger.warning("Using latest data as fallback")
df = data_provider.get_historical_data(limit=limit)
```
**Impact**: Trains on correct historical data, not current data
---
## Training Data Composition
### Per Annotation
| Sample Type | Count | Repetitions | Total Batches |
|------------|-------|-------------|---------------|
| ENTRY | 1 | 100 | 100 |
| HOLD | ~30 | 25 | 750 |
| EXIT | 1 | 100 | 100 |
| NO_TRADE | ~30 | 50 | 1,500 |
| **Total** | **~62** | **-** | **~2,450** |
### 5 Annotations
| Sample Type | Count | Total Batches |
|------------|-------|---------------|
| ENTRY | 5 | 500 |
| HOLD | ~150 | 3,750 |
| EXIT | 5 | 500 |
| NO_TRADE | ~150 | 7,500 |
| **Total** | **~310** | **~12,250** |
**Key Ratio**: 1:30 (entry:no_trade) - Model learns to be selective!
---
## What This Achieves
### 1. Continuous Data Training ✅
- Trains on every candle ±15 around signals
- Not just isolated entry/exit points
- Learns from continuous price action
### 2. Negative Sampling ✅
- 30 NO_TRADE samples per annotation
- 15 before signal (don't enter too early)
- 15 after signal (don't chase)
### 3. Context Learning ✅
- Model sees what happened before signal
- Model sees what happened after signal
- Learns timing and context
### 4. Selective Trading ✅
- High ratio of NO_TRADE samples
- Teaches model to wait for quality setups
- Reduces false signals

# Unicode and Shape Fixes
## Issues Fixed
### 1. Unicode Encoding Error (Windows) ✅
**Error:**
```
UnicodeEncodeError: 'charmap' codec can't encode character '\u2713' in position 61
UnicodeEncodeError: 'charmap' codec can't encode character '\u2192' in position 63
```
**Cause:** Windows console (cp1252 encoding) cannot display Unicode characters like ✓ (checkmark) and → (arrow)
**Fix:** Replaced Unicode characters with ASCII equivalents
```python
# Before
logger.info(f" ✓ Fetched {len(market_state['timeframes'])} primary timeframes")
logger.info(f" → {before_count} before signal, {after_count} after signal")
# After
logger.info(f" [OK] Fetched {len(market_state['timeframes'])} primary timeframes")
logger.info(f" -> {before_count} before signal, {after_count} after signal")
```
---
### 2. BCELoss Shape Mismatch Warning ✅
**Warning:**
```
Using a target size (torch.Size([1])) that is different to the input size (torch.Size([1, 1]))
```
**Cause:** Even though `trade_success` was created with shape `[1, 1]`, the `.to(device)` operation in the batch processing was potentially flattening it.
**Fix:** Added explicit shape enforcement before BCELoss
```python
# In train_step() method
if trade_target.dim() == 1:
trade_target = trade_target.unsqueeze(-1)
if confidence_pred.dim() == 1:
confidence_pred = confidence_pred.unsqueeze(-1)
# Final shape verification
if confidence_pred.shape != trade_target.shape:
# Force reshape to match
trade_target = trade_target.view(confidence_pred.shape)
```
**Result:** Both tensors guaranteed to have shape `[batch_size, 1]` before BCELoss

## Files Modified
1. **ANNOTATE/core/real_training_adapter.py**
- Line 502: Changed ✓ to [OK]
- Line 503: Changed ✓ to [OK]
- Line 618: Changed → to ->
2. **NN/models/advanced_transformer_trading.py**
- Lines 973-991: Enhanced shape enforcement for BCELoss
- Added explicit unsqueeze operations
- Added final shape verification with view()
---
## Verification
### Unicode Fix
- ✅ No more UnicodeEncodeError on Windows
- ✅ Logs display correctly in Windows console
- ✅ ASCII characters work on all platforms
### Shape Fix
- ✅ No more BCELoss shape mismatch warning
- ✅ Both tensors have shape [batch_size, 1]
- ✅ Training proceeds without warnings
---
## Notes
### Unicode in Logs
When logging on Windows, avoid these characters:
- ✓ (U+2713) - Use [OK] or [✓] in comments only
- ✗ (U+2717) - Use [X] or [FAIL]
- → (U+2192) - Use ->
- ← (U+2190) - Use <-
- • (U+2022) - Use * or -
### Tensor Shapes in PyTorch
BCELoss is strict about shapes:
- Input and target MUST have identical shapes
- Use `.view()` to force reshape if needed
- Always verify shapes before loss calculation
- `.to(device)` can sometimes change shapes unexpectedly
---
## Summary
✅ Fixed Unicode encoding errors for Windows compatibility
✅ Fixed BCELoss shape mismatch warning
✅ Training now runs cleanly without warnings
✅ All platforms supported (Windows, Linux, macOS)
