I use different types of strategies and when they are triggered at the same time, it is difficult to find out which strategy has placed an order. Can you advise whether it is possible to change the line type and order colour for different strategies in the MoonBot terminal?

: Strategy settings

Yes, it is possible. Use three parameters in the MoonBot terminal in the strategy settings on the User Interface tab: UseCustomColors, OrderLineKind and SellOrderColor.
The UseCustomColors parameter can be set to NO or YES (NO is the default). If UseCustomColors=YES, you are allowed to change the line type of this strategy using the OrderLineKind parameter (solid/pointed and others from the menu) and the colour of Sell orders of this strategy using the SellOrderColor parameter, using the built-in colour palette.
