to 111, you buy 17 more futures. The total position gamma was 17 and, sure enough, the total position delta went from 0 to positive. The futures have now risen one point to 113. You want a position that is delta neutral, which means you must now sell a spot on the same asset to balance out your delta. Of course, we now have to take out the 120 in time decay for a total intra-day gain of 7,880. The total position delta would now be about -17. With the futures at exactly 112, you decide to buy a 50-lot in 112 straddles (50 calls and 50 puts at the 112 strike). T-bonds go up to 113; you sell short 17 futures. In this case, you sell short 13 more futures contracts. Thats a further increase in options value from 101,600 to 125,000, or 23,400.

When you start out with a position that is delta neutral and long gamma: every time the underlying moves, up or down, you make a profit; every time the underlying moves up, your positions delta increases, and every time the underlying moves down, your positions. The next day, the markets go wild. The puts and the calls each had a gamma.17. Delta hedging, delta hedging volatility on its own is less complex, but it does add to your risk. If you missed that change, you would not adjust your holdings in time to keep your delta neutral.
Gamma scalping in as plain of terms as possible. At this point, you are delta neutral, which is what you want. This brings you back to delta neutral. Action time, now, this scenario has us long 50 straddles at a strike of 112, which were bought when the futures were at 112. In this simple example, gamma scalping showed that money could be made where it is typically lost. Rarely do we rely on gamma scalping to exceed our daily theta. You are no longer delta neutral.
