System 1:
X halftime in "Liga 1" games with no closing line favorite of less than 2.00
Example : CFR (2.00) --- X (3.20) --- Petrolul (4.00)
2014/2015 season : 75W-65L ( 53.57% wins )
Lowest estimated odds for halftime X in such games : 1.95
Estimated ROI for 2014/2015 : 6.25u ( 4.46% profit )
2015/2016 so far : 16 wins - 9 losses
Next steps:
add 2 seasons of data from Liga 1 to see if the system holds
add at least one season from 2 other leagues to see if the model can be applied leagues other than Liga 1
