Not able to on E-Trade.Didn't get a chance today, but will buy more call contracts tomorrow. BTW, are you/anyone able to buy or sell options contracts after hours? Fidelity says that you can in a brokerage account, but I have never been successful getting an order filled.
Side note: E-Trade recently changed up their charts, and earnings-revenue graph pages and they are super glitchy. I need to look into this.
