What does +400 mean in betting?
+400 means a $100 bet wins $400, and a $10 bet wins $40. The price says it wins 20.0% of the time, so at +400 you make money on bets that win more than 20.0% of the time.
In plain words
+400 is a longshot: $10 wins $40, and $100 wins $400.
The price says about 1 in 5, or 20.0%. One win covers 4 losses, so a longshot only has to land a bit more often than 20.0% to pay over time.
Size it small. Even a good longshot goes cold: at 20.0%, the chance of ten straight losses is 10.7%. Keep longshot bets to one unit (1% of your bankroll) or less. Never bet the house on one bet.
