A comment, an icon, rounding and an offer.

US Horse Racing Off Times have been a problem for bot developers since the year dot. The US off times are just a guide and are not religiously adhered to like the rest of the world. Initially I got around this by polling the Time to Post stat that gives a guide of when the off time is due. This value can be scraped from a number of different sites. Even this was a little hit and miss. What I eventually landed on was waiting till the overround was less than 105% to indicate that the race was about to go off. Works quite well in sparse US markets where all the money comes in at the end before the off.

Thanks for this comment. I’ve looked into scraping times and have found a few sites. Not made any attempts to integrate yet. The idea of watching the overround is very good and something I hadn’t thought of. This goes on the to-do list, thanks.

 

 

I’ve been coding an app in Visual Studio to replicate a spreadsheet I’d made when I was doing the matched betting thing. I added an icon and thought I’d add it to this site, so if you haven’t noticed, it should be at the top of the address bar and look like this –

I like the simple look, which is fortunate. And it should show up as different to WordPress in any bookmarks, or in the blog roll on green-all-over (It’s been quiet over there recently).

 

The app I’ve made calculates the lay stake at given odds. A problem I encountered whilst testing my little app was a difference between what I calculated and what I was seeing on the Betfair site. It’s only small but at large stakes it’s noticeable and any discrepancies are worrying, suggesting an error in the formula used. My error came down to rounding. Initially I was just rounding the result only to 2dp. Each step of the formula requires rounding to 2dp to keep it accurate. At no point can you place a lay stake of £50.083333. Attention to detail is key, my mistake.

 

Talking of attention to detail, I recieved an offer to try out a VPS in Dublin with less than 3ms delay. That’s extremely fast for sports trading and probably as good as it gets without co-location (something I’m sure goes on). I had looked at getting a Dublin based VPS when I was setting up but was not willing to pay the obvious premium rate. The offer I received came via Twitter and the first thing anyone does is look at the website of the people making the offer. I remember this company was looking for people to trial its VPS about a year ago. Their website still has some pages that haven’t been altered from the template settings – the blurb you get when you start a website from a pre-made layout offered by these site builder outfits. There’s a lot of trust when putting your bots onto a VPS and you want to know you’re in safe hands that pay attention to detail. I declined the offer.
