# Create a dedicated user (never run trading bots as root)
adduser trader
usermod -aG sudo trader
su - trader

# Update system
sudo apt update && sudo apt upgrade -y

# Install Python and dependencies
sudo apt install python3 python3-pip python3-venv -y

# Create project directory
mkdir -p ~/trading-bot
cd ~/trading-bot

# Create virtual environment
python3 -m venv venv
source venv/bin/activate

# Install dependencies
pip install requests python-dotenv

# Upload your bot code (from your local machine)
scp -r ./bot/* trader@your-server-ip:~/trading-bot/

# Or use git
cd ~/trading-bot
git clone https://github.com/your-repo/trading-bot.git .

# Create a .env file for secrets (never commit this)
cat > .env << 'EOF'
CLAW_API_KEY=your_tickatlas_api_key
TELEGRAM_TOKEN=your_bot_token
TELEGRAM_CHAT_ID=your_chat_id

# Enable and start

# In your bot code, configure file-based logging:
import logging
from logging.handlers import RotatingFileHandler

def setup_logging():
    logger = logging.getLogger("bot")
    logger.setLevel(logging.INFO)

    # Rotate logs at 10MB, keep 5 backups
    handler = RotatingFileHandler(
        "logs/bot.log", maxBytes=10_000_000, backupCount=5
    )
    handler.setFormatter(logging.Formatter(
        "%(asctime)s %(levelname)s %(message)s"
    ))
    logger.addHandler(handler)

    # Also log to stdout for journalctl
    logger.addHandler(logging.StreamHandler())
    return logger

# View logs in real-time
# journalctl -u trading-bot -f
# tail -f ~/trading-bot/logs/bot.log

# Add a health check cron job that alerts you if the bot stops
# Create /home/trader/check_bot.sh

#!/bin/bash
if ! systemctl is-active --quiet trading-bot; then
    curl -s -X POST "https://api.telegram.org/bot$TELEGRAM_TOKEN/sendMessage" \
        -d "chat_id=$TELEGRAM_CHAT_ID" \
        -d "text=ALERT: Trading bot is DOWN on $(hostname)"

# Add to crontab
crontab -e
# Add: */5 * * * * /home/trader/check_bot.sh

# Deploy updates safely:
cd ~/trading-bot
git pull origin main
source venv/bin/activate
pip install -r requirements.txt

# Restart the bot
sudo systemctl restart trading-bot

# Verify it started correctly
sudo systemctl status trading-bot
journalctl -u trading-bot --since "1 minute ago"
