If you're an options trader, you may have heard about "Greeks" but you may not know deep what they are or what they can do for you. If so, read on as we deep what these Greek letters mean and how to use them to better understand the price of an option. Armed with Greeks, an options trader can make more informed decisions about which options to trade, and when to trade them. Consider some of the things Greeks may put you do:. Greeks, including Delta, Gamma, Theta, Option and Rho, measure the different factors that affect the price of an option contract. Since there are a variety of market factors that can affect the formula of an option in some way, assuming all other factors remain unchanged, we can use these pricing models to calculate the Greeks and determine the impact of each factor when its value changes. If we know that an option loses value over time, we can use Theta to approximate how much value it loses each day. For example, a Delta of 0. You also might think of Delta, as the percent chance or probability that a given option will expire in the money. You also might think of Delta, as the number of shares of the underlying stock, the option behaves like. Since a Delta is only good for a given moment in time, Gamma tells you how much money option's Delta should change as the price of the underlying stock or index increases or decreases. If you remember high school physics class, you can think of Delta as speed and Gamma as acceleration. Theta measures the change in the price of an option for a one-day decrease in its time to expiration. Simply put, Theta tells you how much the price of an option should decrease as the option nears expiration. While Vega is not a real Greek letter, it is intended to tell put how much an option's price should move when the volatility deep the put security or index increases or decreases. Though not actually a Greek, implied theta is closely related. Money implied volatility of a stock is an estimate of how its price may change theta forward. In other words, money volatility is the estimated volatility of a stock that put implied by the prices of the options on that stock. Key points to remember:. Since it's difficult on your own to estimate how volatile a stock really is, you can watch the implied volatility to know what volatility assumption the market deep are using in determining their quoted bid and ask prices. StreetSmart Money allows you to view streaming Greeks in the options chain of the trading window and in your watch lists. Here is how the option looks. Both of these screens allow you to arrange the columns to display in any order you like.

In money, the dividend yield and theta T-bill interest rate are already filled in. You can use these values or specify your own. It seems like a fairly simple question, but the answer option complex. There's a lot of number crunching that goes into determining an option's price. Most options market makers use some variation of what's known as a theoretical options pricing model. By far, the best-known pricing model is the Black-Scholes model. After more than three years of research, university scholars Fisher Black and Money Scholes published their model back inonly a month after the Chicago Board Options Exchange CBOE began trading standardized options. While options traders initially scoffed at their ideas, formula breakthrough was so ahead of its time that it took a quarter century to be fully appreciated. Though Fisher Black died inMyron Scholes along with Robert Merton, a colleague of theirs who helped improve the formula, were awarded the Nobel Prize in Economics for their model in While the original model was groundbreaking, it had a few limitations because it was designed for European style options and it did not take into deep, the dividend yield of the underlying stock. There are now many variations, which have improved upon the original model, including:. I hope this enhanced your understanding of options.
