How to interpret daily currency fixings

Hi,

How do you interpret these? Are the highs and lows of the daily candle fixed at the 4pm London Fix what about the NY and Tokyo fix?

Thanks.

There has been a whole investigation about the fixings, the investigation is still going. It appears inst. traders coordinated their trades through chat rooms at the fixings. I am uncertain whether highs/lows can be used but a large movement is often seen when M&A deal is due (I am assuming you are an experienced trader and know the effects M&A's). The biggest reaction during fixing hours are end-of month and end-of-year. The main one's are ECB and London fix.
