this week ... there have been few days where ARCA
is not making markets in mining stocks pre market
now ... they never really make a market ... its just GTC orders usually on their book ...
but on the dozen or so stocks I look at including ETF's
there are few if any bids and offers ...
so I am curious ... did the customers just stop
placing orders as GTC or did any MM who ARCA used for
pre market liquidity go on vacation ?
