@ Ex-hft,
I'm pretty sure you'll understand me.
SING provides interesting market odds for lower-division soccer games, but also offers other major sports such as Basketball when it is needed.
There are ways to precisely avoid cancellations on their end if you're not greedy. Some limited positions in markets with positive expected valued market positions, avoid any arbing approach here. Remember Aristotle's thought "Greed knows no boundaries" and act on it (I doubt SING managers know it, but who knows...)
Some other Asian/Caribbean Minotaurs are pretty excellent here also, provided that you know when and how exactly to open the appropriate value positions there, for example, Super Bowl LVIII is coming...
