If you don't follow all your signals and bet, then you won't have the performance.
The best thing would be pure value bets, a maximum of 10 signals per day, for which you only need 2-3 reputable bookies.
pinnacle e.g.! is that not possible?
From what I can see, this is positive EV betting. Basically you bet with an edge. Over the long term and mathmatically this is proven to work if you are consistently betting with an edge. It takes time and often a lot of volume is better too. You are more than likely going to come out positive if you are consistently betting over 1% expected value atleast.
