hello im an experienced options trader and i would like to start trading the bund/bobl/schatz. can anyone help me with the basics? 1. how do i get the implied yield? 2. what are the ratios between the bund/bobl/schatz deltas? is there a direct way to calculate a delta? 3. is there anything like implied volatility or a standard deviation that affects the price? 4. what is the basic way of pricing the bonds? is there a model i can use (like the B&S in the options)? 5. is there a way to decide which one of them is more attractive at the moment? 6. are there any arbitrages between them? 7. any more tips before i get started? thanks a lot !!!
