Don't get too complicated trying to explain simple stuff.
Look, here's a good options education site:
http://www.interactivebrokers.com/en...&ib_entity=llc
Remember the CBOE ? sign up for the free CBOE site. They have an agreement with optionsxpress in which optionsxpress provides about 12 to 15 free courses about options. Heck, open an account with optionsxpress just for its educational material. They are expensive so, open it with $2000 and place 1 or 2 trades every few months to keep it open.
Delta, Gamma, Vega, Theta, otherwise known as the greeks, and volatility constantly change and therefore the direction of the trade (left, right, left, right...) so instead of overtrading, place a trade and forget about it. Just manage it but do not overtrade...if you get bored post on this site, etc ...
BTW: Try not to trade options just on price, that is one of the cardinal sins. Always, always look at the option volatility (not the stock BETA, BUT the option volatility). If it is too high, the option is expensive, if it is too low, the option is cheap.
The holy grial of trading options is: How to know if volatility is high or low ? There's 2 volatilities I use: Implied volatility and historical volatility. Compare one to the other to get a feeling but usually when implied goes above historial then it is high and therefore the options price is high. Thinkorswim has all this information readily available in one place so you do not have to use sites like ivolatility.com. Thinkorswim also has probability analysis, the greeks, volatility analysis, prophet (go to prophet.net to learn about it), charts, spread scan, MarketWatch from WSJ, risk profiling, etc ....
Obviously, the best broker to trade options ? Thinkorswim. It is expensive but their platform worths its every penny. Everything in one place. I vote optionsxpress #2 and interactive brokers #3.
SOMETHING VERY IMPORTANT: If you insist on buying options only, never buy them out of the money (I'll probably be selling them to you)... The probability of them expiring worthless is too high...
