SMi is 10 SFR per point which is about £4 so quite low compared to the dax-
It used to be ok, with quite wide range and intially i was doing ok, but the range has shrunk, together with the others !! although today it was not bad-
the spread can be wide, ranging from 1 to 4/5 points and like NB says not too liquid- if u can afford the dax, stick to that-
