Most asset classes move in a fairly straightforward manner. They're either going up or down at any given time. But when it comes to currencies it's not that simple.

Everything's relative. So what drives these relative movements, and how do traders decide what bets to place? On this week's episode of the Odd Lots podcast, we talk to Ken Veksler, a currency trader, and director of Accumen Management about how this market operates, and how he navigates it.
