EOD

EOD is an abbrevation of End of Day which is qute often used financial company. It means the time when we estimate the profit or loss about products we have. It must be done every day, and it must be of cousre correct. Especially it is very important for financial company, particulary swap houses which deal exotic derivatives. There are some reason for this.
At first, derivatives are not real products. They are not fruits, fishes, sweets, nor oils. They are only the kind of contracts which promise specialized cash flow. So we have to estimate how much the price is every day.
Secondly, Exotic derivatives are difficult to price. Exotic, as you can imagine easily by this word, is not a simple product. So we have to simulate them by using complexity logic. it might be impossible only by using simple formulation.
From this point, EOD are quite related with quants developers. It is not too much to say that quats developers' task are almost to manage that EOD has been done every day correctly.
