A concern I have now is USD weakness, particularly vs SEK. I don't intend to "trade" by changing account currencies - mostly because that would be a futile endeavor given my lack of skills in the area, and my algo platform works better with USD. However, I might have to look into an algorithmic hedging strategy to reduce my worst case currency risk, at the expense creating some costs/realized losses (which can be comfortably exchanged against the gains realized from my trading activity, prior to taxes). Last week has been pretty viscous on USDSEK, which is now down almost 4% from peak. Considering taxes will be paid on gains denoted in SEK at time of trade close, the practical effects can be even worse than that.
