I want a coin to be guaranteed to be bought in the market after the strategy is triggered, how can I do this?

: Strategy settings

This can be done by using buyPrice: The buy price (in %) of the price at the time of the strategy trigger (when Use30SecOldASK=NO) or the minimum price of the last 30 seconds (when Use30SecOldASK=YES). In order to buy a coin on the market, set this value to a positive value (with a margin), e.g. buyPrice=3.
