Seeking Alpha says that... For long options, delta values are positive for calls and negative for puts. A bought (long) call will have a delta between 0 and +1, rising as the option becomes more in-the-money. A purchased put option will have a delta between 0 and -1, with delta falling the further the put is positioned in-the-money. Moreover, merrilledge.com states that... Gamma goes to 0 when Delta has reached 0 (out-of-the-money) or +1 / -1 (in-the-money) at expiration. In other words, a Delta of 0 at expiration means the option is worthless as the market price is more favorable than the strike price. A Delta of +1 or -1 at expiration means the option is worth executing as the strike price is more favorable than the market. And the Tokenist explains... In theory, theta can be any number, but in most cases, it's going to be anywhere between 0 and -1. Everything "above" -1 is considered to be a big theta number as it deducts more of the option's value. So then, what the heck is going on with that chart in the previous post that I copied from orats.com?
It took some doing, but I finally tracked down a broker who offers an options demo account without requiring me to give them my mobile phone number... https://tradersunion.com/interestin...ing-apps-for-stocks-and-options/options-demo/
Okay, but they don't have any Greeks in the table either. Instead, they have these little blue buttons (which I have pointed out using yellow arrows) that list them in a drop-down menu. But when I click on them, implied volatility is always 0.00% and all the rest of them say 0.0000. So what gives? Do the markets have to be open for the Greeks to register any kind of values?

Delta is a measure of the sensitivity of an option's price to changes in the price of the underlying asset. It is one of the most important "Greeks" used in options trading, and it can be used to estimate the probability that a stock will move in the same direction as most underlying options contracts. For example, let's say you invest $50,000 in Chevron (CVX) and you decide to use options to hedge your long investment position. You can use Delta to estimate the probability that Chevron's stock will move in the same direction as most underlying options contracts. If you have a Delta value of 0.6 for an option, it means that the option goes up or down 60 cents for each dollar that Chevron's stock moves. Another example is when you are buying call options that are at the money, so at $175. If we have a Delta value of 0.468 for an option, it means that for every dollar that Apple’s stock moves, the price of this option moves around 47 cents. In summary, Delta can be used to estimate the probability that a stock will move in the same direction as most underlying options contracts. It can also be used to understand how much an option's price changes with respect to changes in the price of the underlying asset. So, my friend...to remember this, think: Delta Dollar
Microsoft Copilot in Edge... What is a real-life example of how Theta can be used when trading stock options? Theta is a measure of the rate of decline in the value of an option due to the passage of time. It is also referred to as the time decay of an option. Theta is generally expressed as a negative number for long positions and as a positive number for short positions. Here's an example: Suppose you have bought a call option on Tesla with a strike price of $700. The option costs you $20, and it has a Theta of -0.05. At the beginning, your option has 30 days until expiration. If all other variables are constant, your option will lose value as time draws closer to its maturity. Theta, usually expressed as a negative number for long positions, indicates how much the option's value will decline every day up to maturity. In this case, your option will lose $0.05 per day until it reaches the expiration date. Think "DOUBLE T" (theta, time) So, are you saying that when the option reaches expiration, it will have only lost $0.05 × 30 = $1.50? Also, I thought theta was dynamic and changes over time.

Gamma is a measure of how much an option's delta changes when the underlying asset's price changes. It is one of the "Greeks used in options trading, and it can be used to assess the risk of an options portfolio. Here's an example: Suppose you have bought a call option on Tesla with a delta of 0.5 and a Gamma of 0.1. If the underlying stock associated with the option is currently trading at $10 per share, and it increases to $11, the delta would increase to 0.6. Conversely, if the stock price decreases to $9, then the delta would decrease to 0.4. This means that for every $1 move in the stock's price, the Delta will be adjusted by a corresponding 0.10. Another example is when you are buying call options that are at the money, so at $175. If we have a Gamma value of 0.05 for an option, it means that for every dollar that Apple’s stock moves, the Delta value of this option moves around 5 cents. In summary, Gamma can be used to assess the risk of an options portfolio and estimate how much an option's delta changes when the underlying asset's price changes. Think Gamma go... (to delta)
Microsoft Copilot in Edge... What is a real-life example of how Vega can be used when trading stock options? Vega is a measure of an option's sensitivity to changes in implied volatility. It can be used to estimate how much an option's price will change for every 1% change in implied volatility. For example, let's say you buy a call option on Tesla with a Vega of 0.05 and a premium of $10. If the implied volatility of Tesla increases by 1%, the option’s price will increase by $0.50 (0.05 × $10). Conversely, if the implied volatility decreases by 1%, the option’s price will decrease by $0.50. Another example is when you are buying call options that are at the money, so at $175. If we have a Vega value of 0.05 for an option, it means that for every 1% increase in implied volatility, the price of this option will increase by around $0.05. (What? But, 0.05 × $175 = $8.75!) In summary, Vega can be used to estimate how much an option's price will change for every 1% change in implied volatility. Think: Vega Volatility

Rho is a measure of the sensitivity of an option's price to changes in the risk-free interest rate. It can be used to estimate how much an option's price will change for every 1% change in the risk-free interest rate. For example, let's say you have bought a call option on Tesla with a Rho of 0.25 and a premium of $4. If the risk-free interest rate increases by 1%, the value of the call option would increase from $4 to $4.25. Conversely, if the risk-free interest rate decreases by 1%, the value of the call option would decrease from $4 to $3.75. Another example is when you are buying put options that are at-the-money, so at $175. If we have a Rho value of -0.05 for an option, it means that for every 1% increase in the risk-free interest rate, the price of this option will decrease by around $0.05. In summary, Rho can be used to estimate how much an option’s price will change for every 1% change in the risk-free interest rate. Think: Rho Risk-free Rate
