At the time of writing this, there is a sell order for 18.21 BTC for 300GP making it 16.4745 GBP/BTC

However there is also a buy order for 45.2 BTC for 840 GBP making it 18.5841 GBP/BTC

A guy is willing to pay £18.5 for BTC and somebody is willing to sell for £16.47.

Is there a problem with the site where the orders are not being matched and the trade not happening?

Many thanks
