A delta value of 0.5, therefore, tells you that for every $250 change in the value of the underlying futures, the option changes in value by about $125. If you were long this call option and the S&P 500 futures move up by one point, your call option would gain approximately $125 in value, assuming no other variables change in the short run. We say "approximately" because as the underlying moves, delta will change as well.

How many long call options to hedge short futures?
In other words, you need two long call options to hedge one short futures contract. (Two long call options x delta of 0.5 = position delta of 1.0, which equals one short futures position). This means that a one-point rise in the S&P 500 futures (a loss of $250), which you are short, will be offset by a one-point (2 x $125 = $250) gain in the value of the two long call options. In this example, we would say that we are position delta neutral .
Why are call deltas positive?
Keep in mind, these call delta values are all positive because we are dealing with long call options, a point to which we will return later. If these were puts, the same values would have a negative sign attached to them. This reflects the fact that put options increase in value when the underlying asset price falls. An inverse relationship is indicated by the negative delta sign. As you'll see below, the story gets a bit more complicated when we look at short option positions and the concept of position delta.
