Arbusers

Hi , all dear arbusers . It is years I have been here . So I started arbing again cs` have more time for it .
I playing whit Idea to apply trading managment to arbing . Lay the Draw  and if Winner will be 1 or 2 is  30 % + 37 % = 67% and that there will be draw is only 33 % so if we find arb to lay it and we will apply reward 1:1  it should be profitable  . That mean if there  wil be draw we loose if no we win . so we can be 33x1p wrong lets say  and 67x1p win what make as 67-33= +34p from 100 maches . Let me know your ideas .
