Sharp vs Square Money

Sharp money comes from winning, professional bettors; square (public) money comes from casual recreational bettors. Lines that move against the public ticket count usually indicate sharp action on the other side.

• Reverse Line Movement (RLM) — When the line moves opposite to the public ticket count — a classic signal that sharp money is on the unpopular side.
• Steam Move — A sudden, uniform line move across many books at once, driven by coordinated sharp betting — fast-moving professional consensus.
