if your SELLLVL: is set to 2 you will not see much selling with SELLLVL2: set to 5 ... try setting it lower, to 1, and keep the other settings or just slightly tweak.

"BUY_LEVEL": 0.1,
"GAIN": 0.6,
"EMA1": 16,
"EMA2": 8,
"HIGH_BB": 41,
"LOW_BB": whatever you fancy, it aparently works if the bot is buying OK,
"STDV": 2,
"SMAPERIOD": 50,
"SELLLVL1": 2, I would consider also lowering this a bit, maybe 1.2 or 1.5 or even less, 0.8 would work to speed
things up
"SELLLVL2": 5,
"SELLLVL3": 70,
"SELLLVL": 1, set this to 1 to start sell cycle earlier
