RE: All 2.20 are sells ... Unable to get a quote to buy14 Jul 2020 18:02
In My experience MM's play games with buy and sell prices to try and stimulate the market, refusing quotes, random drops on sells to try and grab cheap shares, high buys after a number of quotes and ignoring orders.
when something happens the next day people connect the dots, but from my experience it happens all the time.
Test it yourself, find a quiet share. request quotes for a decent chunk of shares, repeat it 3 or 4 times for the exact same number, see what happens on the 3rd or 4th request.
