You have to:
change the wallet_password, that’s the password which will be used by the cli_wallet.
change the account name, for example “liquidity-bot-linouxisbot”
change watch_markets to the markets you want your bot to watch and therefore trade.

The wallet_password and account should be new / non-existing ones, should they? And can the wallet_user be left empty?

I tried to set up a bot but gotexchange-bot_1 | Account creation failed and exchange-bot_1 | https://bitshares.openledger.info/ response: {"status":"500","error":"Internal Server Error"}
