Click a race to load it into the app.

If a race is slightly light then its a closed market, if the race cannot be clicked then its been abandoned.

The link icon to the right of each race will open the market in Betfair in a new window.

Race Details

When you load a race the race details will show above the runner information. Non UK / IE races have basic information.

UK and Irish racing shows class, distance, handicap status, going, race type, number of runners and race track characteristics. These will show when they are available again after resuming post corona virus lockdown.

The 'GRID' view is shown by clicking 'GRID' on the right and it is the default view on loading a race.

The grid can be sorted in order by clicking on the column header such as runner number or name.

A row with a green background indicates the winner of the race.

  • Draw (if available and not on the silk).
  • Silk / saddle cloth number.
  • Horse Name.
  • Day Chart is the last 10 hours of data, this may be less in the case of AUS racing where data is limited due to the nature of the markets.
  • Recent Chart is the last 10 minutes of trading.
  • Prices - Betfair Back and Lay price + BSP if the race is settled
  • WAP (added 10/04/2020)
  • Odds - the odds at the ''time to post' selected in the header.
  • Move - the difference between the odds either side. The last odds uses the current price for the 'too price'

Odds time options save automatically and are saved in 2 groups, GB and IE races use different defaults that all other countries. This is because it is likely you'll want to see data much closer the to race off time for non GB / IE races.

Choose the 'htp' - 'hours to post', or 'mtp' - 'minutes to post' from the drop down to see odds from that time.

Steamers are show in GREEN and drifters in RED. The larger the movement the deeper the colour, a very light colour symbolises a small movement.

Charts View

The 'CHARTS' view is shown by clicking 'CHARTS' on the right and will stay selected when moving between races.

Blue: Back

Red: Lay

Green: WAP
Grey: Volume Traded

WAP is Weighted Average Price. This takes into account amounts traded on each price (odds). If, say, £100 has been traded at 5.0 and £1000 at 6.0, the 'normal average; would be 5.5, the WAP is 5.91. This results in a nice smooth chart that is easy to see real price movements.

The first chart is the 'Market Maturity' chart. 

The blue and red lines are how far away from a 100% that side of the market is. 

When the blue 'back book' line and red 'lay book' lines are inside the green bar then the market is reasonably mature. (5% gap in book). The time scale on the runner charts start when the market was 'mature' according to that rule (or a preset amount of time if its not).

Click the 'Market Maturity' chart where you want the runner charts to start from. Click near the right of the chart to see recent data, and to the left for more of the days odds data.

Settings Tab

General settings can be set here

Movement calculations per country are optional so you can decide what calculation is use for the movement between adjacent odds.

Book Difference, eg:

5.0 to 10.0 = (100 / 5 - 100 / 10) = (20 - 10) = 10

Ticks Difference, eg:

5.0 - 10.0 = (5,5.1,...9.6,9.8,10) = 30 Ticks

Percentage, eg:

5.0 - 10.0 = 10 - 5 / 10 = 0.5 = 50%
