Autotrade didn't work today

I’ve been subscribed to, and autotrading, for a few months now. Everything has worked well and all trades were placed. However, a position was opened today by the developer but the autotrade feature didn’t work for me. I’ve been left out of the trade. I’ll need to find out what went wrong. If I had insufficient funds to make the trade would I get a message telling me so? Any advice would be greatly appreciated.
