I read somewhere that when a opening total crosses a number that can be divided by 7 or 10 to produce an whole number (meaning no decimals), then it becomes a key indicator on which side of the total you should play because that line shows to be inflated to attract square play
for example, total opens at 48.5 and crosses 49 to 49.5 .
49 / 7 =7
49.5 / 7 or 10 = 7.07 or 4.95
this indicator is similar to crossing 3 and 7 ATS
in this example, playing the under would be proper.
does anyone have more info on this?
