sure, but if speed is the issue then the only way I see to make it faster is to lower your time, I might be wrong there though. There will be some changes that happen so fast that it will be hard for a bot or for a human to get the buy or sell order in fast enough.
Could be an issue, what did it look like on the bot graph? Did the colour reflect the same indication as in the bot signal graph?
I had ok results with 20 seconds but yea everyone should test it out for themselves.

I get "attempted to divide by zero" not sure what I did to get this notification in the debug log
