That's a bug in Gekko, if you could let me know some details (like are you running the latest version, what exchange and interval) I will look into it!
I have updated now
git pull https://github.com/askmike/gekko.git && npm update
and I am on Bitstamp
interval is 30
still the same
ADVICE is to HOLD @ 85.810 (NaN)
which part of config.js do you need?
(BTW: is there any possibility to git pull without to fill out config.js every time new? - I rename the existent to .bak and copy/paste the settings in the new one)
