yes, there normally is a big change in the bids/offers on the depth of market as soon as they issue the price
i still haven't traded today. still waiting for the bl**ding obvious.
one clue might have been the high in the future of 4055.5. i am informed the EW BOR is 4006. the market loves to move in 50, 49.5 and 49's (as well as 15, 30 ......!) but the market is a bit oversold, so i'm being cautious
