Best practices for Binomo trading bots

A good strategy can be wiped out by a bot that crashes, leaks a password or trades without limits. These practices keep your bot safe.

  1. Risk management
  2. Credentials and security
  3. Session and connection handling
  4. Trading mechanics
  5. Logging and monitoring
  6. Respect the platform

Risk management

  • Start on demo, stay there until the numbers say otherwise. Run every new strategy for hundreds of demo trades before you risk real money.
  • Use a fixed, small stake. A common rule is no more than 1–2% of your balance per trade.
  • Set hard stops in code: a maximum number of trades per session, a daily loss limit and a minimum balance. See the signal bot example.
  • Avoid martingale (doubling after a loss). A short losing streak can wipe out the account.
  • Check your balance yourself before each trade. Compare balance.amount * 100 with your stake, which is in minor units.

Binary options are high-risk. Most retail traders lose money. Nothing in this library or its docs is financial advice.

Credentials and security

  • Load credentials from environment variables or a .env file, and never commit them. Add .env to .gitignore.
  • Treat the auth token like a password. Debug logs and the login console output contain it.
  • Redact tokens and cookies before you share logs in issues or on Discord.
  • Use a separate device ID per bot so sessions don’t clash.

Session and connection handling

  • Create the client with create_from_login() so the authenticated session is reused.
  • Use async with so the WebSocket is always closed, even after an exception.
  • Call await api.connect() once at startup so your first trade isn’t delayed.
  • For bots that run for hours, catch AuthenticationError and log in again (example).
  • Retry network errors with exponential backoff, never in a tight loop (example).

Trading mechanics

  • Pass RIC codes ("EURO"), not display names ("EUR/USD"). See the Asset List.
  • Prefer OTC assets for testing. They’re open 24/7.
  • Mind expiry alignment. A 60-second trade expires on the next whole minute that is at least 30 seconds away. Details.
  • Send orders sequentially over one client rather than in parallel.
  • "submitted" means sent, not accepted or won. Check the result on Binomo.

Logging and monitoring 

import logging
logging.basicConfig(
    level=logging.INFO,
    format="%(asctime)s %(levelname)s %(name)s: %(message)s",
    handlers=[logging.FileHandler("bot.log"), logging.StreamHandler()],
)

Log every trade receipt (ref, asset, direction, amount, time) so you can match it against your Binomo history later.

Respect the platform

Automated trading may be restricted by Binomo’s terms of service, and that is your responsibility. Keep request rates reasonable: the 5-minute balance cache exists for a reason.
