SPDR S&P 500 (SPY)

Blasher, don't want to speak for NM, but from my observations he uses 10 contracts as a base, then doubles, triples, etc., but he then relates everything back to 10 contracts or 1000. Soooo, 18 would be $18K.
Notice when he makes .15, but says it's a double, so .30 will be recorded, all he is saying is:
20 contracts(2000)*.15 = $300 OR 1000 * .30 = $300
Kind of goofy, but different strokes for different folks!!
