I'm looking for a list of the most popular futures contracts and their multipliers. So for example, NQ -> 20 ES -> 50 etc. Does anyone know where such a list exists?
The most popular (highest volume) futures contract in the world is the Bund traded on EUREX. Its BigPointValue ("multiplier") is 1000 Euros. Your broker is a good source of information for point values, tick sizes, hours traded, expiration dates, market holidays, and so forth.
Here's an article you may be interested in. EuroDollar futures traded on the CME were the highest volume futures contract in the world, at least for the first half of 2007. http://www.futuresindustry.org/downloads/Volume.pdf
YG mini gold is $3.32 per $0.10 tick or $33.20 every $1.00. Margin required is 1121/830 overnight and intraday with IB.
