the thing is that I want to make returns, not to answer the phone (I do not say this to underestimate the work is fine, it just does not relate to what I want)
What you say no longer exists. There are very few companies that make their own returns and they do not need many people to do this. What you are saying is 15-20 years ago when bwin had a specialist in 2-3 countries to make odds for each league.
Now all this is automated and the whole industry is looking for automation so that the active potential covers the live. That is, to be the one who sees Milan at 2.50 and is right, if the market has Milan at 1.80 and you 1.80 you will necessarily give and you will lose your job if you have 2.50
All odds are sent by the betrayer and adjusted by each bookmaker based on the rake.
All you have to do is trade live and support phones. When we say live do not imagine that you watch the match and set the prices according to what you see. Again, prices come automatically and change depending on what people bet and the models that each company runs in terms of time. You have to lock it unlocks the market when it has a foul or when a lot of money falls and the model is late to change the price and to control / reject dangerous bets that are coming.
Essentially what you need is knowledge of how the arbors move, knowledge of the reasons for price changes and a knowledge of risk management.
I do not know if you are still covered by working in a betting company, but since you have no experience, you will need recommendations and you will go through many tests, losing many hours until they take you normally.
However, this as a book does not exist, it changed gears.
