Refresh Rate, Requests, Throtling

[keesbart]

Hi,

I would like to know the relation between:
- Refresh Rate
- Requests
- Throtling.
I have set the throtling in the preferences to 15.
During In Play I have:
Refresh Rate: 203(40)
Requests: 8-10 (most of the time)
Can somebody explain to me what this means?

About 1-2 weeks ago the Refresh Rate was much lower, mostly between 100-120. Now it is most of the time above 200.
Also I noticed that in the preferences the Refresh Rate is now set to 0.2 (was 0.1 before).
Can somebody explain?

When you open BA and log in (and have chosen no market yet) there is an
information about that:

Fastest refresh rate increased from 0.1 to 0.2 seconds

Unfortunately we have had to increase the minimum refresh rate. This is to
keep the product in line with Betfair’s product requirements. See vendor
product requirements for further details. The relevant paragraph is the 4th
paragraph in part B under “Data Request Management”. Version 1.1.0.65q
includes this modification.

Therefore you have a refresh rate of 0.2 seconds = 200 milliseconds. The
throttling is meaningless in your case because your requests are below it
anyway.

Thanks Milfor for your reply.

Does the Refresh Rate of 200ms mean that the spreadsheet is updated every 200ms for all the data of all the sheets in the spreadsheet at once?
I have 2 pages (win- and place market) connected to 1 spreadsheet (sheet1 has the data for the win-market, page 2 has the data for the place-market).

Yes, both worksheets are updated every 200ms. The actual refresh rate displayed at the top of the screen should be around 200ms. To achieve this you will need to set the throttle limit to 20. Each sheet requires 10 requests per second (5 prices and 5 bets) which is a total of 20 requests per second. Betfair charge you for requests in excess of 20 per second so you cannot run any other Betfair software at the same time or you will be charged.

Thanks Gary for this information

How do you get an actual refresh rate of 200ms? mine has remained showing 1000ms despite increasing my throttling from 10 to 20.

[GaryRussell]

Changing the throttle limit does not change your refresh rate, it changes the maximum requests per second that the application will make.
You can change your default refresh rate in general preferences or the betting options in the top left hand corner of the application.

Here is a video demonstrating changing the refresh rate for the current market and then changing the default refresh rate so the next market uses the new refresh rate.

Thanks Gary, specsavers for me, been looking all over for that

"Betfair charge you for requests in excess of 20 per second"

Surely, whilst that is true they do offset these charges against your betting turnover, don't they ?

And you can see these details under the 'Account' menu.

If Betfair had their way, we'd be getting just one refresh a minute before they'd start charging !!

Don't go giving them ideas, next thing they will be trying to sell us that as progress.

Given that they have transaction charges in place, I can't think why Betfair have imposed this new rule, other than to coerce a few extra people into paying them £200 a month to use the API.

There's a very funny Beavis and Butthead cartoon where Beavis says of the Bon Jovi video they are watching, "Do you remember when these guys used to be cool?" and Butthead replies, "er, no". That's what I think of Betfair nowadays.

As a suggestion, if the refresh rate on a spreadsheet is set below 0.2, Betting Assistant could use 0.2, rather than ignoring it. Throttling would still safeguard against any unforeseen transaction charges.
