Close at stop?

hi all,

i have been back testing forexfunnel for sometime and i realised the huge loss at the end of the graph, was due to close at stop. can someone who knows about this ‘close at stop’ thingy please explain to me why are trades being closed? i have set the duration of test to be the whole of last year since 1st Jan 2008 to 31st Dec 2008, but due to massive close at stop, my results only lasted till some where March. i am new to trading with EAs, thus i guess i need a bit of explanations here.

thanks,
ken.

By the way i tested it in a demo acct and my friend did his in a live account and he don’t experience the crash of high equity. can someone help in explaining?
