BSP vs PPWAP

Hi,

Can anyone explain the key difference in how the BSP and PPWAP odds are derived on Betfair?

(For instance is BSP = PPWAP + bets placed in SP market in Betfair?)

Thanks

Hi
BSP is calculated by Betfair's own SP reconciliation process. Details here:

PPWAP is Weighted Average Price of all bets placed on a selection pre-off
