Hi!

I have background in stat-arb and market making the the stock market, and recently been looking at sports betting just for fun. The comparison between the betting market and stock market is obvious. I got curious about playing around with market making to see how it would work. Im not looking for moving around huge amounts where liquidity would be an issue, just small amounts for fun. So could any kind person help me with these question and maybe save me alot of time?

* Will the exchanges let you use their API for moving around placed bets frequently, or will they limit you in some way if they dont think you contribute enough? One would think that the exchanges likes market makers since the increase liquidity, but from experience, I know companies does not always act rationally.

* Is the spread generally wide enough to overcome the commisson? Commission of 0.75-3% seems huge to me.

* Does it still exists market making opportunites today, or has the market matured enough to make it a futile project?

Cheers!

1. Depends, in general they are not happy when their APIs are used or manipulated.
2. Yes, commissions are huge.
3. There are opportunities and ways to make money here.

Thanks for your reply!

I´m a bit puzzled why the exchanges wouldn´t like it when you use their API.. Or do you mean if I for example just read all the market info without placing any serious orders, they will shut me down? My idea was to put in limits near the current price and hopefully get filled quite often. And maybe modify my order 5 times a minute. Do you think they would let me do that?

Cheers
