I don't use any services, systems, or programs. Like you, I tried , but nothing too sophisticated or too successful. I feel that is a dead end road. If it could be done successfully, it would be done, and even if you did it, people with more $$ and bigger edge would exploit it till it no longer existed. My "edge" is reading the lines like I do people at a poker table. I also am very knowledgeable about Sports, sports mentality, and strategy. I have watched and bet on literally thousands of games for 20 years now, so I have definitely seen it all. I have a trading background, so I understand odds and probabilities more than most. I am not afraid to win big. I learned this from trading. The daily grind is unwinnable if you don't exploit the hot streaks. Increase on winning streaks, and decrease on losing streaks. It also helps that I have a huge bankroll. I have been able to sustain some sizeable losses in my betting career. I love situational betting (good spots, bad spots, etc.).
