Look: the betting market is choking on noise, and the first filter is the scalpel you need. You’re watching a tote board flash, you think you’ve got a winner, but the race type hidden behind the name is the silent killer. Open races, graded races, class races — each one behaves like a different beast. If you ignore the filter, you’ll chase phantom hares and waste cash.

Open vs Graded – the quick showdown

Here is the deal: Open races are the free-for-all, the scrappy street fights where any greyhound can step up, regardless of form. Graded races, on the other hand, are the club-level fixtures, a hierarchy where dogs are grouped by ability. The odds in open races swing wildly, like a roulette wheel on a stormy night; graded races are tighter, more predictable, like a well-tuned engine.

What the filter actually does

By slapping the race type first filter onto your data feed, you instantly separate the chaotic from the controlled. It’s not a fancy algorithm; it’s a binary switch. When you select “open,” you’re telling your software to only pull events where the entry list is unrestricted. Choose “graded,” and you get the curated sets where dogs have been vetted by past performances. The difference is as stark as night versus day, and it shows up in your win rate.

How to set it up in a flash

First, locate the race-type dropdown in your platform. Click “open races.” Done. Need graded? Flip the switch. If you’re using an API, append race_type=graded to the query string. No fuss. The key is to make this filter a default step, not an after-thought. Every time you pull a dataset, the filter should be the first line of code, not the last.

Common pitfalls and how to avoid them

Don’t assume the label “open” always means the same thing across tracks. Some venues call a “Class 1” race “open” even though it’s effectively graded. Double-check the track’s definition page. Also, never rely on a single filter; combine it with distance and trainer stats for a sniper-level approach. Ignoring these nuances is like shooting blindfolded.

Real-world impact on your bankroll

When you apply the filter correctly, you’ll notice a shift in your ROI within a week. Open races give you the high-risk, high-reward opportunities — perfect for a small bankroll looking to explode. Graded races smooth out volatility, ideal for steady growth. The secret is to allocate a percentage of your stake to each based on your risk appetite. Mix them, don’t hoard one.

Final tip

And here is why you must treat the race type filter as non-negotiable: it’s the gatekeeper to relevance. Skip it, and you’ll be drowning in data. Embrace it, and you’ll be surfing the wave of profitable odds. For a deeper dive, check out this race type first filter UK greyhound article.
