Yes. Your question was really what is the tick size. The answer is half a point. Bitstream was just wasting space (or maybe he thought the tick size was one point and didn't know the difference between tick and point...having seen other posts from Bitstream, I'm pretty sure he was just being cute.)
Ok, thanks. I am not familiar with futures. I trade forex. So tick size is synonymous with spread? Interesting.
Not technically. The spread is the difference between the bid price and the ask price. In a liquid market the bid/ask spread is usually equal to the smallest possible price increment, which is one tick. In this case, one tick is half an index point. Edit: I assumed that's what you were asking. Maybe you meant how many ticks wide is the market usually, in which case maybe Bitstreams comment was not as smartassed as I thought.
