Scalability Analysis

Memory Usage

# Memory usage grows linearly with dataset size
# Formula: Memory = Base + (Dataset_Size * 0.007) MB

# Example:
# 1,000 points: ~7 MB
# 10,000 points: ~70 MB
# 100,000 points: ~700 MB

Time Complexity

# Most operations are O(n) or O(n log n)
# Technical indicators: O(n)
# Portfolio optimization: O(n) to O(n)
# LSTM training: O(n * epochs * features)

Optimization Tips

1. Use Appropriate Data Types

# Use float32 instead of float64 for large datasets
df = df.astype('float32')

# Use categorical data types for strings
df['symbol'] = df['symbol'].astype('category')

2. Enable Multi-threading

import os
os.environ['OMP_NUM_THREADS'] = '4'
os.environ['MKL_NUM_THREADS'] = '4'

3. Use Chunking for Large Datasets

# Process data in chunks
chunk_size = 1000
for chunk in pd.read_csv('large_data.csv', chunksize=chunk_size):
    # Process chunk
    pass

4. GPU Acceleration

# Use GPU for LSTM training
import torch
if torch.cuda.is_available():
    device = torch.device('cuda')
    model = model.to(device)

Performance Recommendations

For Small Datasets (< 1,000 points)

  • Use default settings
  • No special optimization needed
  • All features perform well

For Medium Datasets (1,000 - 10,000 points)

  • Consider using float32 data types
  • Enable multi-threading
  • Use chunking for data processing

For Large Datasets (> 10,000 points)

  • Use GPU acceleration for ML features
  • Implement data chunking
  • Consider distributed processing
  • Monitor memory usage

For Real-time Applications

  • Use pre-computed indicators where possible
  • Implement caching strategies
  • Consider using faster libraries for critical paths
  • Optimize data structures
