It works whenever it is not tired, my friend.
I can't find any other pattern based explanation.
You see, in soccer two things matter in all strategies:
1. Goal scoring
2. Time passing
If we are not sure for (1) all relevant strategies must be excluded.
There are not left a lot of things...

The only things that are important in trading are the relevant back and lay prices of the chosen markets. The actual score in a football game is of of little importance to anybody. I appreciate that the scoring of a goal will have a direct impact on prices. Triggers have to be made so as to operate as a result of these price changes and not to operate in consequence of events during a game, goals, yellow cards, red cards, offsides, etc.
I cannot see how Welldone can do any more. Soccer markets are often suspended without good cause as the guy on the Betfair button panics as a result of believing he has seen something when nothing has actually happened. This causes great difficulty for those trying to make triggers but I am afraid it is something we have to learn to live with.
Asa comparative newcomer to MFP I already find making any set of triggers a challenge. My past experience of trading soccer matches manually for many years has led me to believe that soccer is one of the more difficult sports to automate. Pre-race and in-running horse racing is comparatively simple.
