Malcolm explains how we can know the Betfair SP and bet based on Betfair SP before the off!
Just about every system you come across on the web would first have been created using past data.

If this is the case then the result will be shown using either SP (Industry Standard starting price) or BSP (Betfair Starting Price) for results.
There is nothing really wrong with this because it is the only way of giving people the chance to check the results they are seeing as being accurate.
But where it does cause an issue and pose a problem is when it is a price sensitive system or a system that relies on being on a particular ranked runner, like the favourite.
BSP and SP are calculated at the off.
You may think by looking at the ranking a few seconds before the off will tell you who was favourite, second favourited etc…
But often this isn't the case. The BSP/SP announced ranking can be different to the just before the off rank.
A short test we did with Betfair some time back clearly showed that the rankings can differ by as much as 1 or 2 runners in every 10.
Maybe this doesn’t sound too bad…
…But when you consider you could be following hundreds or even thousands of bets over the course of a year…this could easily change the results you were expecting or the results being advertised.
The same is true of price. The price before the off is often different to BSP/SP causing even more inaccuracies in your system.
So what can you do to make sure you are on the correct runner or within the correct price range?
You may already know that just as Betfair's market goes in-play the BSP price and ranking is made available through their API.
So we have developed a great feature on the Grey Horse Bot that allows the bot to read the BSP price and Ranking as soon as it happens.
This gives the Grey Horse Bot user the opportunity to choose which ranked runner to bet on or to only place a bet into the market if it is within the price range you require.
When you create your own system it should be part of your testing to determine if you get better prices before the off or in-play. You can test both automatically with the Grey Horse Bot.
Thank you for reading I really do appreciate it.
