Where the data comes from
A scanner is only as good as its data and its speed. Ours reads the venues directly, with no middlemen in between.
This is the boring part reviews usually skip. A pity, because it’s where most scanners break. Nearly all the value of a scanner sits in two things: how close its data is to reality, and how fast you get it.
We connect to the venues directly
Not through aggregators, not through data resellers, not through someone else’s API with a trimmed line and its own delay. Pulse reads the same feeds a venue sends to its own website.
The difference shows immediately. When a scanner takes its data from a middleman, there are at least two extra links between the real price and your screen, each with its own delay and its own failures. We don’t have that link.
Honest numbers
ROI is calculated with fees and the liquidity that’s actually available. Not a shop-window percentage that looks great in the feed and dissolves the moment you try to bet.
An arb doesn’t vanish from the feed for no reason. A market only leaves the feed when the venue has taken it down.
Three kinds of pairs
| Pair | What to expect |
|---|---|
| Book vs book | The classic. Familiar interface, a bet goes through in a second |
| Book vs exchange | Usually the fattest percentages: the pricing mechanisms differ, so they drift apart more often |
| Exchange vs exchange | Rarer, but these arbs live longer: exchanges even out slowly |
A separate plus of exchange arbs: an exchange doesn’t cut you for winning. Your result doesn’t matter to it, it earns on volume. With bookmakers it’s more complicated, and the more venues you have, the calmer you can be. See Limits and restrictions.
