Using a correct score strategy

After watched a few trade video's, it seemed pretty easy to make money with a correct score strategy. I realise it only looked easy cause in practice it is very hard to think clear and stay with your strategy.
Cause i don't have much experience, I will start with a small budget of €20 per trade.

Before I enter my first serious trade, I will give formulate my strategy. It is as followed:

Before the trade

1.  First I will Back the 0-0, 0-1 and 1-0
2. I will do this with stakes of the amount the profits wil be equal. Divide the budget of €20 about the three choices.
3. It is important that we try to manage that our potential liability is not more than the doubled amount of your budget. So if you start with €20, maximum liability is €40. But only if there is not another way.

The trade

1. We have to protect our current position. Normally the first goal of a match is scored between the 15th and 30th minute of a match. So it is important to trade the 0-0 before the 20th minute. Therefore I have a rule. Start with trading the 0-0 if, the first 15 minutes are over or if the starting odd has fallen down to 75/80% of the starting odd.
2. Then look at how the match is going. If it is more likely that the 1-0 will be scored than the 0-1? Be sure thata part of the profit of the 0-1 is transferred to the 1-0. You can do this by simply laying a part of 0-1 bet or backing the 1-0 bet.
3. If a goal is scored, be sure that the next possible scorelines are safe. So if the 1-0 is scored, back the 1-1 and 2-0. 

Backing stakes are scalped of the possible profits.

I will start with my first trade with this strategy in mind. I hope it will have succes.
