I believe there are professional pick 3/4 players but they are not willing to share their winning software/techniques for obvious reasons. For example...it took me 16 years of pure hardwork/sweat to perfect/research and write my own software program. There were many many times that I wanna quit thinking it was an impossible task ...but something inside me telling me to get going...to persevere ...to believe that nothing is impossible.
The key to success or to find your own profitable pick 3/4 system is to persevere...don't quit no matter what...to keep on believing though it may seem impossible...because nothing is impossible.
BTW ...my system is a combination of mathematical formula based on current trends and Indonesian mystical numbers system.
