I would suggest the latter. 20 lots is a lot for QG, especially when you consider natural's volatility.
I bot some lots yesterday when offereed, and it popped immediately and the higher offers disappeared immediately. Looks like someone was trying to spoof the market, so when they bid it higher immediately, I sold it out. Spoofing the market is a silly game. Lets all keep an eye on this and maybe make some "mad money" as cramer says!
Its the middle of summer, just look at nat gas, my gosh what will it go to this winter. This is insane.
I dont truly understnad energy mkts, but have been making money for the last month,so, will stay with it. Have given up trading er/es/nq as they are losers for me now.
