Having seen his account James19 is not a trader, but an arber, and he's using 'OddsTrawler Pro' to get his arbs.
I Don't think he's an Arber,
not by my definition of the word anyway.
He's said he uses a model to find value and then greens up when the odds realign,
Smarkets confirmed this by telling him not to green up against the market makers.
SO to me he's just a trader that exploits short term value, like alot of us on here do .
I myself use models to help in my trading sometimes
and yes im sure it could be said that some of the out of line prices were also by coincidence arbs too, but most are not.
It's a dangerous precedent to set on what is a very gray area. AS All winners win by getting value of some sort.
