CTD, futures, price, dollar duration

Finished Q15 of Schweser Exam 3 (vol 1) PM and got some questions. Just want to get a shortcut summary. Price DD Duration CTD (1) (2) D1 Futures (3) (4) D2 (1) is normally given in the question, right? You don’t really have to calculate it. (2): is it just D1 x (1) x 0.01 x bps change? Do we need to scale it up to match the portfolio size? (This is what’s done in the solution, to come up to $10,596.40) (3): how is it related to (1) or other parameters? (4) = (2) / conv. factor ---- right? How are D1 and D2 related? Thanks. - sticky
