Formula for calculating Betfair SP

[LetsGoAgain]

I have a BOT that puts lay bets on a single horse every 15 secs beore the jump depending on what has been matched and odds available

At the 5 seconds mark I would like to issue the Global command Take_Sp_All

But I need to have a fair idea of what the SP odds would be so I don't get burnt

The BOT gathers a lot of information at the 5 second mark like:
Back odds & $$$ available / Lay odds & SSS available / LTP / Runner volume on this horse and Total runner volume per race

Does anyone know how to calculate the BSP using that above info

Thanks in advance

IMO opinion it is physically impossible to calculate BSP with absolute certainty. Not sure if you have seen the following, but this link may help:

Hi Letsgoagain I have recently put a post on the suggestion board to ask if the Betfair Projected SP could be included in the spreadsheet data that was available through Guardian. Don't know if it would help you as well. Definitely help me. Unless tehy can get all the events to go off on time...
