Your trading agent is managed through a dedicated Telegram bot (https://t.me/ttmt_agent_bot) that communicates with your MetaTrader instance. This bot is built to help you change settings quickly and securely—all without needing to log into a separate interface. Here’s a step‐by‐step explanation of what happens when you use the bot to update your trading instance settings:

1. Changing Your Default Lot Size

Command: /set_lot_size

What It Does

The default lot size controls the base order size your trading instance will use when executing trades. When you update this setting, the bot does the following:

• Prompts for Input: If you start the command without an argument, the bot will ask you to type in a numeric lot size (for example, “0.2”).
• Validates Your Input: The bot checks that the value you provide is a valid number.
• Updates Environment Variables:
  • The bot calls an API (via Coolify) to update your instance’s environment variable for default_lot_size.
  • It also calculates a corresponding “high risk” lot size (70% of the default, but no less than 0.08) and updates that setting too.
• Restarts the Instance: To ensure that your new settings take effect, the bot restarts your trading instance.

Example Interaction

User: /set_lot_size
Bot: Please enter your desired default lot size.
User: 0.2
Bot: Updating default lot size... ⏳
Bot (after update): ✅ Successfully updated default lot size to 0.2.
         High risk lot size set to 0.14.
         Restarting instance to apply changes...

Alternatively, you can also pass the lot size directly with the command:

User: /set_lot_size 0.2

2. Setting Your Maximum Risk and Auto-Calculating Lot Sizes

Command: /set_max_risk

What It Does

This command is designed for those who want the bot to automatically calculate your default lot size based on your maximum risk per trade and your account leverage. The process works as follows:

1. Risk Entry:
   • The bot asks you to enter your maximum planned risk per trade in USD (for example, “50”).
