It doesn’t make much sense to me. It means.. whenever the bot detect a difference of 0.1 % in prices he will trade?
Answer
-0.1 is so that the bot can make it instant (most of the time)
If it says -0.1 , then it will only open the position if the price gap is >-0.1 . If it says 0.3 , then it will only open the position if the price gap is >0.3
