It indicates the amount the delta would change given a 1 point move in the underlying security. If the gamma is small, delta changes slowly, and adjustments to keep a portfolio delta neutral need to be made only relatively infrequently. However if Gamma is highly negative or highly positive, delta is very sensitive to the price of the underlying asset. It is then quite risky to leave a delta neutral portfolio unchanged for any length of time.
Figure below illustrates this point. The size of the error depends on the curvature of the relationship between the option price and the stock price which is known as Gamma.
Thus Gamma Neutrality protects against large changes in the price of the underlying asset between hedge rebalancing. It is defined as the rate of change of the value of the portfolio with respect to the passage of time with all else remaining the same.

It is sometimes referred to as the time decay of the portfolio. It helps the trader identify the right strike to trade under a given circumstance. It also helps the trader identify the right strike to trade under a given circumstance.

This decrease in delta reflects the lower probability the option will end up in-the-money at expiration. How delta changes as expiration approaches Like stock price, time until expiration will affect the probability that options will finish in- or out-of-the-money. Because probabilities are changing as expiration approaches, delta will react differently to changes in the stock price. If calls are in-the-money just prior to expiration, the delta will approach 1 and the option will move penny-for-penny with the stock.
In-the-money puts will approach -1 as expiration nears.
If options are out-of-the-money, they will approach 0 more rapidly than they would further out in time and stop reacting altogether to movement in the stock. Again, the delta should be about. Of course it is. So delta will increase accordingly, making a dramatic move from. So as expiration approaches, changes in the stock value will cause more dramatic changes in delta, due to increased or decreased probability of finishing in-the-money. But looking at delta as the probability an option will finish in-the-money is a pretty nifty way to think about it.
As you can see, the price of at-the-money options will change more significantly than the price of in- or out-of-the-money options with the same expiration. Also, the price of near-term at-the-money options will change more significantly than the price of longer-term at-the-money options. So what this talk about gamma boils down to is that the price of near-term at-the-money options will exhibit the most explosive response to price changes in the stock.
Long and Short of Option Delta
But if your forecast is wrong, it can come back to bite you by rapidly lowering your delta. But if your forecast is correct, high gamma is your friend since the value of the option you sold will lose value more rapidly. Theta Time decay, or theta, is enemy number one for the option buyer.

Theta is the amount the price of calls and puts will decrease at least in theory for a one-day change in the time to expiration.
Notice how time value melts away at an accelerated rate as expiration approaches. In the options market, the passage of time is similar to the effect of the hot summer sun on a block of ice.
Check out figure 2. At-the-money options will experience more significant dollar losses over time than in- or out-of-the-money options with the same underlying stock and expiration date.
And the bigger the chunk of time value built into the price, the more there is to lose. Keep in mind that for out-of-the-money options, theta will be lower than it is for at-the-money options. However, the loss may be greater percentage-wise for out-of-the-money options because of the smaller time value.
