Many companies hire traders, the employers need not be a regular bank or a broking firm…it could be companies like -
Reliance / Shell / BPCL etc - They hire crude oil trader and forex traders to hedge their positions in spot
Thomas Cook / Cox & Kings - They hire forex traders
Cargill / Olam / Louis Dreyfus - They hire commodities traders, in fact they are the biggest commodity traders
Banks - They hire Bonds and Interest Rate Futures traders
Family Office - They hire equity traders to private transactions
This list can get quite exhaustive, just be aware that there are highly rewarding opportunities…however they are limited and gets taken away by the best.
