% Higher Than Betfair SP (In Running Tab)

Info:

You can also analyse the In Running High prices of horses by the percentage higher they went In Running in comparison to Betfair SP.

You can use this in many ways, one angle would be to find horses that often trade higher in running for trading, hold up horses, or horses that often dwell or start slowly etc

% Lower Than Betfair SP (In Running Tab)

Info:

You can analyse the Low In Running prices by the percentage they are lower than the Betfair SP.

This can be used to find potential back to lay horses.

You can set the In Running Low percentage to whatever you require and can use the operators > >= < <= AND

Examples would be >50 (this would return results only when the horses In Running Low price was at 50% or lower than BSP)

>=75 and <=95 (this would return results only when the horses In Running Low price was at between 75% and 95% lower than BSP). 

A/E (System Results)

Info:

The A/E index indicates if a statistic is good or bad and is calculated as follows:-

A = Actual Winners
and
E = Expected Winners.

A is easy to calculate as it is the number of winners.

E is the total of all the probability or odds of winning for each horse based on the Betfair SP (minus any commission) prices for each horses

e.g. If we have 100 horses who went off at 3/1 then we would expect 25 of them to win. The odds of a 3/1 shot is 0.25 so adding all 100 of those together = 25.

Once you have the expected number of winners then you just divide actual winners by expected winners to produce the A/E index.

An A/E index of 1.00 means the statistic is performing as expected, less than 1 and it is under performing and more than 1 and it is performing better than expected.

As a benchmark an A/E of 1.25 or greater would be very good and an A/E of 0.75 or lower would be bad.
