1 Attachment(s) Hello everyone,

only a simple question...I was considering the spread graphs posted by Oanda (http://fxtrade.oanda.com/spreads/recent_spreads.shtml) in which they show the spread for different currency pairs within the last 7 days, I started to compare the shift (widening) of this spread with theforexintuitivenews calendar and I can not appear to find the connection between Oanda spreads and theforexintuitivecalendar (supposing that the spreads at Oanda change based on significant news statements ).

For instance, throughout Monday 27/8 and Wednesday 29/8 the chart indies no growth of the spread for EUR/USD, though I see about theforexintuitivecalendar that there were 2 high impact announcements during Monday 27/8:

15:00 EUR ECB President Trichet Speaks HIGH IMPACT
16:00 USD Existing Home Sales HIGH effect

So my question is simple. Is there anyway to expect the spreads widening at Oanda predied on th info offered by theforexintuitivecalendar (or any other calendar)? The actual question is: Why does the spread alters according to significant news announcements or is it just some stuff in order to discourage day trading? . Note that I am not complaining about anything, I just wish to know if they respond to occasions or if the spread changes are arbitrary.

Thanks beforehand and my apologies if there's a similar thread about this, I searched and found a lot of information about Oanda but nothing regarding Oanda spreads forexintuitivecalendar.
