# Read and sort CSV data (reverse chronological) data = [] with open(csv_path, 'r') as f: reader = csv.DictReader(f) for row in reader: # Convert date from YYYY-MM-DD to YYYYMMDD integer date_obj = datetime.strptime(row['Date'], '%Y-%m-%d') date_int = int(date_obj.strftime('%Y%m%d')) # Convert values record = 'date': date_int, 'open': float(row['Open']), 'high': float(row['High']), 'low': float(row['Low']), 'close': float(row['Close']), 'volume': int(row['Volume']), 'open_interest': 0.0 # Default if not provided data.append(record) convert csv to metastock format

# Create MASTER file (simplified) master_path = os.path.join(output_folder, 'MASTER') with open(master_path, 'wb') as f: # Write minimal master record for one security # Structure is complex; for real use, copy from existing MASTER # This is a simplified placeholder f.write(security_name.encode('ascii') + b'\x00' * (32 - len(security_name))) f.write(struct.pack('<H', 1)) # 1 = stock type f.write(struct.pack('<H', 0)) # data format | Field | Bytes | Type | Example

Part 2: Required CSV Format Your CSV must contain these columns (exact names not required, but data is): 'MASTER') with open(master_path

File size in bytes ÷ 28 = Number of records Example: 2800 bytes ÷ 28 = 100 days of data. Using Python, loop through a folder:

import struct import os import csv from datetime import datetime def csv_to_metastock(csv_path, output_folder, security_name): """ Convert CSV file to MetaStock format. CSV must have columns: Date, Open, High, Low, Close, Volume Date format in CSV: YYYY-MM-DD """
