Setting Advanced Take Proft 1-3 via Cbot and Enumerated Choice Buy/Sell

Hi together,

When I open a order I usally use the Advanced TPs funcionalitty and Breakeven funcionality of Ctrader. I'm currently programming a small cbot which opens a new MarketOrder. I want to integrate in my cbot that afterwards the Advanced TPs 1-3  and / SL to Breakeven settings are set by the cbot. It that possible and how?

My second question. As an input parmeter for the cbot I want to have a choice for Buy or Sell. Like an enumerated choice which have this two options. I already tried following argument TradeType but I can't get it to work/compile. Seems like that the TradeType is not a valid parameter type.

Is it not possible to create just a new Enum Parameter with the values I want?
