A word of caution on options quotes and "value" estimates used in calculating unrealized gains or losses: You really have to look at the bid/ask spread, which is quite wide compared to the underlying stock bid/ask spread. Therefore, brokerage accounts use a variety of methods to determine interim performance (which is frustrating, but there's no really good answer).
The "last" trade for options contracts is an automatically wrong method, as the last trade may have been days or weeks ago due to the thinly traded character of most option contracts. Schwab, my broker, for example, uses a hypothetical mid-point between the bid and the ask for intraday quotes and value estimation. This may either undervalue or overvalue what the market really is, but may be the best compromise. Then, at closing, they switch over to the end of day bid, in most cases, I think. This generally understates the value, but is closer to what you could have realized if you traded right before closing. It is sometimes something else entirely, which I haven't figured out.
Just saying, don't confuse option theoretical gains as real until your trade executes - all quotes are an estimate, by nature.
