Hi Jason,
following our exchange re GBPAUD & GBPNZD recently. Looking at my GBPNZD 5M chart this morning, I see that the high-low range of the 5M candle on the RBNZ rate announcement was a around 490 pips.
I cannot recall whether this is typical of the volatility in that pair at the time of RBNZ announcements. My understanding is that the FXCM bid-ask are a pure derivative of the prices from all of FXCM's liquidity providers.
Could you comment as to whether generally speaking the volatility in prices on news releases has increased over recent months/years? I have heard the idea that increases in post-news volatility may be due to the a reduction in prop trading done by banks, thus sucking liquidity from the markets. It would be great if you could comment about that.
By the way, do let me know if I am not meant to be asking these types of questions on this thread!
[As a sidenote, I have been using FXCM for many years. One of the big reasons for it is the responsiveness of the staff and my ability to get hold of someone on the telephone if I have a question.]
