@Everyone:

We've made some improvements to our Betfair price grabber that provides the prices for the backtesting.

Previously, we took a price snapshot once per second and wrote that to the DB for later retrieval in your strategies. 1-second intervals are obviously pretty granular (already resulting in about 10 million price snapshots per month of data 🤣 ) and provide a good indicator of price trends and entry / exit points.

However when a race goes in-play, the prices obviously become very volatile and we've seen that the price can easily dip below or surge above the "snapshotted" price between snapshots, often for significant enough traded amounts that you would want to be aware of it in backtesting (where you're basically always interested in whether the price touched a particular level).

To solve this problem without literally writing every tick to the database and needing a data-centre to rival OpenAI's, we're now analysing the ticks that make up each snapshot in memory and then storing the highest and lowest values as the snapshots.

The upshot of this is a more reliable indication of whether your entry or exit price was hit and therefore a closer correlation between your simulated backtesting results and your real life trading.

This will most benefit people who are exiting their trades in-running, or those doing lay the field type strategies.

@Alex-Rendell it's still not come up with finished product. I keep getting to limit of data analysis for the day🤦‍♂️

@Ryan I would have cashed out when the underdog scored for a very small loss and that would have meant a profitable day 🙂

My new manta is "protect you bank" which is helping with discipline.

@Chris-King very interested in your selection filters. So what angle do you trade using your filters. I can see that you are identifying a strong underdog. Are you looking to back the dog pre match and hope they make a fast start and win the 1st set?

@Simon-Hardy-0:

To find the higher ranked player, filter on:
Player -> Total -> Rank -> less than -> Total for opposition

The problem is you can't then do "price for this player" unfortunately. You can filter on the BF prices via Betfair -> Odds but only referencing specific selections.

If you have the "BF Prices" tab open in the main view, filter on the rank as above and then click each match in the filter results table, you should be able to narrow it down pretty quick.

Cheers fella

So plenty of potential in these systems and i ones that havn't been profitable on will tighten the filters and then show the results if they improve

Not updated for a while but LTD still going in right direction just slow due to kids and life in general meaning i am busy when most trades are happening but the ones i catch seem to be generating small profit.

have just started (paper) trading half dobs on the horse racing and if this works then that would be amazing as i am buy my computer all day for these... we will see.

Full house yesterday!

Today's AI LTDs:
Sangju Sangmu vs Gwangju FC 3.5
Sydney FC vs Melbourne City 3.7
Silkeborg vs Vejle 3.75
Roda vs Vitesse 4.2
Helmond vs Cambuur 4.3
Den Bosch vs Jong PSV 4.3
Jong AZ vs Maastricht 5.3

@Lee-Greener No worries, we'll disable the non-scope version of that strategy rule in a future update (like we do with "horse position") as it's literally impossible to use to backtest an upcoming race!

Ive traded the power play on 2 games in this T20 WC, both With the Black caps batting first....and the kiwis have not let me down!(although went on to lose v South Africa)Screenshot 2026-02-27 135837.png

@Lukáš-Bíňovský what's the multigoal strategy?

I have a similar one, these are my settings:

I don't bother with the "Sport Specific" ones, and more often than not it trades out for profit after the 1st goal, provided its early enough.

@Adam Fantastic, thanks very much! 🙂

@Martin Many thanks for your help so far. Appreciated.

@James-Menhenitt Think of xG less as "expected goals" and more like "expectation of a goal". It's basically the probability that a given shot made by the average player will result in a goal.

A value is given to each shot based on tons of factors, including distance and angle to the goal, type of shot (header, volley, etc), position of the keeper, the type of pass that led to the shot, etc. The xG values for each shot are then added together to give an xG value for the whole match.

The Overall > Average > xG in the software then takes the last 10 home matches for the home team and the same for the away team, and gives you the average xG figure per match over that match history.

Happy New Year!

Watched the videos — really good stuff. Had a 7-hour car journey so I smashed through the podcasts as well, some of them more than once.

I’ve been trading LTD and FHG using 2% of the bank and after just two trades this morning I’m already not far off doubling my original bankroll.

I’m big on stats and the software just makes everything feel smoother and easier to manage. I’m pretty strict with discipline too — some days one bet hit the target and that’s it, I was done for the day.

@Martin said in Starting Over:

Thanks Martin.

I am still paper trading this but it is throwing up so many ideas. I am amzed how much I have learnt from so few matches, approx 210.

I will update again when I start trading this on Betfair.
