I will be happy to open the topic with a tool I am using and developing. I am using bettingmetrics to keep track of all my bets and analyse them. I think Bettingmetrics is much better than just a an excel spread-sheet because of the following reasons: 1. There is an API feed that shows suggestions all the time so it helps me save time while tracking my bets 2. I can import my history from betfair exchange, that is something I like 3. All bets logged will be auto settled 4. The analytical tools are tailored made for betting and extremely easy for using 5. No technical knowledge is required I am also using some matched betting calculators when i spot an opportunity. What are you guys using?
