Good question. Personally I only use FUNDS_RESERVE but I see RESERVE_PILE_UP still appears in config.js file. However it doesn’t appear in the GUI. I’m going to figure out why this happens and if it still works on v21+ and I will let you know.
I just talked with lead developer and he checked the code and told me RESERVE_PILE_UP is active. At this moment, the only way to use it is to activate it directly editing config.js but now dev team is warned about this and they will include it in GUI for next version.
So I am enabled and also checked pileup and its showing zero. Reserve_pile_up is true and the bot has been restarted since. I know there has been profit since also. here is the ouput. (Zero is on the beginning of the next line.. no end of line on the QTY “\n”)
