What happens if the SM button with a red arrow is pressed on the main window of MoonBot terminal, a manual strategy is selected and its parameters allow to use Stop Market (UseMarketStop=YES), but MarketStopLevel=0?

: Strategy settings

In this case, when buying a coin in the MoonBot terminal using a manual strategy with the parameters UseMarketStop=YES and MarketStopLevel=0, a take line (Sell order) will be placed, but you will still have the option to move this take line to the opposite stack with automatic replacement by the Stop Market line, as well as the reverse action: you can move the Stop Market line to the opposite stack and the take line will appear again.
Please note that in order to be able to use Stop Market, you should set the slider to the far right on the Settings-Advanced-System tab to “Log level: 5”.
