Reading the ladder

Back (blue): Money available for you to back — offered by layers on the exchange. Best back price is the highest available, directly below or at the LTP. Bar width shows relative depth at each tick.
Lay (pink): Money available for you to lay — offered by backers. Best lay price is the lowest available, at or above the LTP. Tighter spreads (fewer ticks between best back and best lay) indicate a liquid market.
LTP: Last Traded Price — the most recently matched price, highlighted in cyan. In liquid markets the LTP sits between the best back and best lay. Sudden LTP movement (steam) signals a directional shift in the book.
Weight of Money: Ratio of total available back volume to total available lay volume across all visible ladder levels. Back-heavy WoM (blue bar >50%) suggests the market expects the price to shorten. Lay-heavy suggests drift.
Tick ladder: Betfair prices must be valid exchange ticks — the increment changes at fixed price boundaries. Submitting a price of 3.14 to the API returns INVALID_ODDS; it must be rounded to 3.15 (the nearest valid tick in the 3.00–4.00 band). Use the rounding tool above to verify prices before placing orders.
