In the log I saw something like: already working on that market. Wont place another buy order sorry., AutoStart: FALSE Already working. Autodetect ON, and additional orders are not placed, what does this mean?

Already working” means that there is already one order on a coin and MoonBot won’t place the second and subsequent orders without multorder mode.
To remove this error and allow the bot to place multiple orders on one coin, you need to enable multiorder mode (press the M button on the main window of the MoonBot terminal).
The multiorder mode and use of the M button are available only to PRO version owners with activated Moon Scalper module.
