correct me if I'm wrong...
if you stop loss in previous market, you lose another oportunity to get green...
ex: match beggin
0-0 -- 1º lay
1-0;0-1 -- 2º lay ... if the game stay like this you win both lay´s, if not
2-0;0-2;1-1 -- 3º lay ... if stay with 2 goals you win 2º and 3º lay
.... you just won, one lay if the game has 4 goals.... and yes, lose everything if a 5th goal scored...
i think and like you said, if we choose the restrictively games with some constant in it, we have 2 chances to be winner...
what you think, about it?
