@Jonathan-Jones how do you get two winners?

I know Adam has said before that sometimes if the data changes from betfair it takes a while to update the backtesting. Whenever I spot anything that seems wrong or out of sync with my results I mark it a different colour and go back to it in a couple of weeks to see. Tbf it hardly happens so most of the time I just ignore it

Anyone any idea what this is all about?
Ripon 18:40 yesterday.
This is what he software backtest says:

For a very nice total profit of 25 points.

Except its complete fiction.

These are the bets actually taken:

Exactly the same bets yet it resulted in a loss on the race of a fraction of a point.

Interestingly fairbot looks like this:

So, i am guessing photo finish or something and the winner was changed. The software has the wrong winner.

I've been away for the past week and took a break from trading. Has LTBF righted itself or is it continuing to be a pain? The backtesting shows it's still struggling

Adam

@Joseph-Henderson It depends entirely on the criteria in your strategy.

If there's anything in there that could change between 07:00 and 13:30 then yes, that could change your qualifiers.

Joseph Henderson

@Adam Does this mean if you download the Daily Qualifiers at say 7am and upload them to BFBot, then not all selections that would appear at say 1.30pm will necessarily have pulled through by that time. I’m using a stripped filter so didn’t think the time I downloaded Daily Qualifiers mattered, but maybe I’m wrong. This might explain why my results from the Bot vary a bit to the results in the software, which is bugging me!

@Toyin-Butler said in The BTC Horse Racing Thread:

@Adam Just a thought, would it be possible to have an updated at reference on qualifiers?

Yes possibly, it's on the roadmap

@Greg-Mitchell said in The BTC Horse Racing Thread:

@Adam Quick Question on the software, if I use the "Traded Rank" filter, and say chose just Rank 1 and then add whatever other filters I feel like. Then set it to place the bet at 10 seconds before the start time. Does it pick the horse that is traded Rank 1 at that time or the one that finished the race as rank 1?

Currently the final ranking, which I appreciate isn't useful. We are working on linking various similar stats to the entry time window instead of final values.

OK, so i must of just missed the 12:02. The 14:05 looks about right. So, i guess i need to make sure to allow about 2 hours if i make any changes

Adam

@Jonathan-Jones The times above were the finishing times of the entire qualifiers run (for everyone's active strategies) in BST.

The last couple of times the qualifiers for that specific strategy of yours were updated were (in BST):

08:32
10:04
12:02
14:05

@Adam

The ones are showing are definately old ones. I may of found the cause of my issues with that BestBacks strategy. The strategy is ok, the filter is not. It still had the Favourite conditions. It obviously shouldnt. So, i must of misclicked save at some point or something. Anyway, i removed it this morning. Thought it was about 11 - 11:30 ish, was definitely well before 1. The favourite is still showing in the conditions on my qualifiers (favourite 1-4) so they are definitely wrong.

And:
They have now (in the last couple of mins) corrected.
Too late for the day though.

Those times BST or UTC?

Adam

@Jonathan-Jones These are the timings of each qualifiers update for today so far:

02:00
03:30
05:00
06:30
08:00
09:30
11:00
13:00

What is going on with the qualifiers tab these days? past few days i have been thinking its been slow updating but today i know its not changed in about 2 1/2 hours. I updated a strategy filter some point between 11 and 11:30. Its not updated the qualifiers. They are still the old ones.

Thats me out for the day then.

@Martin I shall nose

@John-Folan think I need you to create some bots for the new strategies I just released!

John Folan

@Jonathan-Jones Fairbot is limited. It’s slightly faster than BFBM but the sheer scale of what is possible as filters on BFBM is brilliant. Ive fully automated my short odds lays so I don’t even need to import selections. (Still got a couple of courses to add to the course filters but that’s it. As they come up they will be added).

The other stuff is auto imported from the software and the filtering gets me a 99% accuracy with the software. Occasional differences but that’s life. I have thrown strategies away if I can’t get them close but that might be more down to being lazy rather than software. For inrunning I use bet Angel for speed. Its filtering however is terrible. Peter Webb has made it too complicated for most.(me included or I would use it for everything. It’s bloody brilliant for manual scalping tho).

BFBM will have the added advantage of automating football as well if you do it once the new revised software is out. Something to bear in mind. They are also pretty good at adding stuff to new releases if they think it’s useful. There’s a few of my suggestions that they have added over the last couple of years. A couple they haven’t. But I want the moon on a stick!

@John-Folan
if you look at the 5th condition thats the favourite one. Fairbot does it by allowing you to set an order then do a compare. So its order by back odds then Back Price (named horse) <= BackPrice 4th horse. I think i have pushed fairbot a lot further than its meant to go and its well past its limits now. If BFBM can sort my issues with late non runners and allow me to run multiple rules against the same horse/ multiple horses in a race then i may just have to stump up the extra cash because there is no doubt my problems with executing according to the strategies are costing me a considerable sum at the moment.

Yes. Number of selections is number of runners

John Folan

@Jonathan-Jones thanks. I’ll have a play and see if I can get bfbm to play ball. I’m not a fan of fairbot as I just feel bfbm is better suited to what we do. Each to their own though. Some people swear by it.

There is no favourite condition though. That’s the only thing I could see throwing it out. But that doesn’t explain why the software is missing those you have said are in the top four that haven’t been taken.

I’m guessing selections is fairbots way of saying number of runners?

@John-Folan

This is one of todays.

2 horses in the selections, a rule set for each.
You may wonder why the apparent duplication of the rules (back price and LTP). Its more of a thing on the lays, probably not needed on the backs but i found a lot of instances on the bigger lays where LTP and best avaible lay price were miles apart. So, it was a case of either go for entry at LTP (and not get matched) or go for entry at best lay and take a possible much bigger loss than intended. So, i added the check to make sure the softwares trigger was taken but i could also get a good price. Its not made any difference on the backs.
