Gamma measures the sensitivity of option delta with respect to changes in the underlying prices. Option delta represents the sensitivity of option price to small movements in the price of underlying asset. Option price is a function of many variables such as time to maturity, underlying volatility, spot price of underlying asset, strike price and interest rate, option trader needs to know how the changes in these variables affect the option price or option premium.

Theta is always negative since if other things remaining same, option value declines as it gets closer to expiration due to diminishing time value. All other option parameters remaining constant, the option value will constantly erode with every passing day since the time value of the option diminishes as it approaches option expiration.
