Just trying out a few things selling Bobl and Schatz options, and I'm having a hard time getting filled. Example: The bid-ask spread in Mar strike 106.2 Schatz calls is 0.03, I make the best ask. Nobody bites. The only trades that go through the market are volatility trades, recognizable by the nice large round volume figures. Nobody appears to be trading outright options or option spreads. The only non-vol trade this morning was some poor guy paying full ask for some March puts - on a 9-tick spread for 250 contracts. Ouch. Is this normal ?
