Hi Jay,

You want to look for markets where there is not a lot of directional movement, where price has been trading in a narrow range. In theory all the ladders in your screenshot look to be suitable candidates, but you would need to watch them prior to starting the robot so that you can gauge how volatile the price movements are at the time.
I prefer not to give precise advice on what setting to use, because it is a matter of personal choice depending on your appetite for risk and because the settings should be chosen by the user to suit the market's available size and volatility at the time. Only you can judge that at the time.
It sounds like you are on the right track, just keep practising with small stakes until you feel you've got the hang of it and are making regular profits.
Kind regards,
Gavin
