telegram.bot.token: Token from @BotFather after creating a new bot.

telegram.chat.id: Chat ID of the Telegram user or group where alerts will be sent.

For group chat IDs, make sure the bot is added to the group and use a negative sign (e.g., -123456789).

MongoDB Settings

#spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=cpa
spring.jpa.properties.hibernate.ogm.datastore.create_database=true
spring.data.mongodb.auto-index-creation=true

MongoDB is used to store signal history and trades.

Default configuration assumes MongoDB is running locally on port 27017.

Database name: cpa
