Trigger being set off by inaccurate football scores.

See attached....

My trigger, which works 99% of the time... is sometimes being set off by non existant goal results....

The trigger fired because it thought the score had changed to 1-0 but it is in fact still 0-0

Unfortunately, the Betfair score service is not reliable enough for trading requirements.  It is far safer to design triggers around the changes in odds that occur when a goal is scored, or use other markets as indicators.  For example I am currently trading the B.Munich v E. Frankfurt match and after 9 min there is still no score available and this is a major game in the Bundesliga.
