Select "+ Remote executer key"
The bot will generate you an external executer key. Use this key to send messages from your trading platform just like other Discord/Telegram keys. But these messages will not be posted anywhere. They will be stored in the bot database. You can get these messages from bot database using the same key in MetaTrader or FXTS2.
So, the workflow will look like this:
Send message using this key -> Bot will store it in the database -> Request new messages from bot database using the same key.
