Will Somebody check this for me..RSI

[RemcoCoin]

Hello,

I'm new with gekko. The system is active and working good.
BUT i have the next questions.
1) I didn't see any green and red bullets in the market graph when gekko has made a trade for me.
2) Gekko is buy too high, and sell to low ??
I'm using the RSI of gekko. and 3 minutes candle's time
What is wrong in the numbers ?
