An ETF instrument I use currently shows a 0.6% spread, approximately 6 times the usual spread on an ETF. What is more, the inverse fund corresponding to it currently shows a 0.1% spread as one would expect, leading me to believe the spread is in error. This is not a temporary glitch - the spread has been about the same for a month. This is in a spread betting account, by the way.
Can anyone suggest how I might "appeal" the spread? Obviously IG can charge whatever spread they wish to - but in this case it does look like it might be an error on their part.
