Each particular option contract has its own trading volume and it is very likely that your option orders aren’t filling because those contracts have little to no volume in the real world. Even options for huge stocks like GOOG and AAPL still have much, much lower volume than the stock itself. Options on smaller company’s stocks often have no volume except for the strike prices that are very close to the stock’s current trading price.
To check the volume of an option you are trying to buy or sell, go to the options trading page and enter in all the details as you normally would when making an order. When you have finished, you will see a quote for the option itself appear right under the company’s stock quote. If the option’s volume is smaller than your order quantity then the order likely will not fill.
