All valid comments I agree. But it ain't what it used to be, last May I'd clip 400 happily intraday, you could go unnoticed, you won't catch me doing anywhere near that in this whippy book. I complained about the 5000*5000 flipper book and 35 tic range years ago and I'll complain about this book too. I like complaining. It's more the speed of change than the change itself, it means a steep adaption learning curve but it keeps you on your toes.
It's not just bund, what happened to noone batting an eylid at 6000 tnote clips into 10,000 it was only a few months back, everyone's chickened out of risk since the crunch. These times they are a changing, still I was slightly concerned we'd be at 25,000 thick book by now the rate it was thickening up at last year, nice to see a flush out in a way but feels like way fewer participants in there, you get noticed by the machines now.
I think there's been a lot of migration of bund locals to eurostoxx, at least there, there's some size left in the book.
