Hi it is definitely the api I have been testing since November on different servers different refresh rates etc and it is nowhere near as good as the old one, I have had to give up my strategies as well, I have contacted betfair but they say there is nothing wrong, I cant really say anything about betting under the minimum to them, which when turned on on the software makes the problem ten times worse. The only thin I domt get is that other people who use in play and fast refresh rates aren't complaining unless they are still in test mose where everything gets matched. cheers Colin
