Using the Chart screen (Chart ), examine an intercommodity Notes-over-Bonds (NOB) spread formed with a T-bond futures and T-note futures contracts similar to the ones you analyzed.

Note that the contracts have to have the same expiration.

a. Use the Chart screen (Chart ) to create multigraphs for the T-bond, and T note futures. On the Chart Menu screen, select Standard G chart; once you have loaded your securities, go to "Edit" to put your graphs in separate panels.

b. Select a period in which you would have taken a long NOB spread position (long T bond contract and short T-note contract) and calculate the profit from opening and closing at the futures prices at the beginning and ending dates for your selected period. Calculate the losses if you had taken a short NOB position (short T-bond contract and long T-note contract).

c. Select a period in which you would have taken a short NOB spread position (short Tbond contract and long T-note contract) and calculate the profit from opening and closing at the futures prices at the beginning and ending dates for your selected period. Calculate the losses if you had taken a long NOB position (long T-bond contract and short T-note contract).

d. Using the annotation bar, apply the "\% Change" tool to calculate the percentage change for your select periods, and then click the "News" icon on the annotation bar to find relevant news events on or preceding the opening date.
