First of thanks for another wonderful explanation Philakone! I have a question about automatic selling and buying on Bitfinex that I can't seem to figure out (not margin trading, but the regular exchange). Maybe you can help me out or one of the other readers.

For example: I own EOS and the price at the moment I want to execute this is $8. I expect it to go to $11 and than retrace to $9. What I want to do is sell at $11 and than buy back at $9 automatically. The selling part is no problem, but I can't put a buy order in at $9, since it hasn't passed this price yet. Is there a way to get this to scenario to work automatically, or will I have to put the buy order in after the sell order has been executed? Thanks in advance!
