August ’17

The streaming version of Gruss is better now, none of the issues of late with missed market list updates or getting stuck on expired markets.

The new Oscar on the Aus horses has performed flawlessly (apart from another schoolboy error that lead to it trading one race the first day out and not moving on). I now need to add all those changes to the UK dogs, not that I have any trouble there but the code is neater and more efficient, so good practice to implement.

I haven’t done any more with the bots other than update Gruss when new beta versions are released, as I’ve been busy with other things.

A good chart from the UK dogs, less up and down than last month.


Generally good for the Aus horses. The sharp up then down was a run of four races where only one back bet was placed. No offset or green bets placed/matched. I’m assuming there was either an API issue or connection problem. These races don’t seem to suffer from early starts, so it isn’t that. And they were different venues. One of those things.

The sharp drop prior to those four errors was a failed offset/greening sequence. There were 7 back bets placed/matched fully but the seventh lay bet wasn’t matched and then greening only partially matched.

These were all before the new code for greening went in, so I’ll have to wait and see if it happens again. I’ve probably said it before but in the long run, these errors tend to have very little effect.


Although I praised the US horses last month, compared to the Aus dogs, this chart has pushed me to stopping the bot. Four missed offset bets resulting in a gain overall. I think the way my algo trades the markets, it just isn’t worth the risk with too few bets placed. There isn’t the turnover to recover in time for the next problem/error.


As mentioned last month I went to the Ebor festival at York for the Saturday races. It was a good event, nice weather, plenty to eat and drink. I’d gone with a tight limit on the betting and placed bets with the on-site bookies, to enjoy the experience. I don’t really like gambling though (in the traditional way), I can’t get past thinking I’m just going to lose as I don’t know anything about picking winners. Won nothing, surprise, but had loads of laughs and enjoyed getting to the front to see the horses race past the finish post, great atmosphere and very impressive. And Saturday night in York was a laugh too, finished with a kebab, “large… hic… everything on it mate… hic…  “, which seems like the best thing ever at the time but probably best forgetting about afterwards, rather than contemplating it’s content.

    1. No, not as a rule. I allow a very small spread to remain active in fast, or low liquidity, markets.

      I did trade gaps when I was doing it manually, on UK greyhounds and US horses. The trick then was to use some other source as a guide to direction and jump in early on markets where the spread hadn’t closed.
