Hi Ya,
I am a complete noob also, but I have managed to buy and sell!
Your settings look OK (almost the same as mine!)
The key to this is patience, the price has not being meet to complete your sale order.
Once price is met, Gunbot will sell.
You just have to be patient... It does work!
Leave your bot running and depending on the market, you will probably wake up to find out you have sold it!
I suggest to leave your setting as they are for the moment, get a few sales in and then play with the BB settings to suit your trading style...
It actually doesn't need a lot of attention, just need to choose the correct trading pair.
Not much help! but I am hoping it was reassuring!
