Just continue as is. First of all, everyone is affected. Second, it's a unpredicatable day today anyway. Third, it's the first day and don't think it will have a hugh impact.
I placed an order to buy CTM yesterday afternoon at about 3:30. The price then was around 42.75-43p. Somehow the ordered was executed this morning at 49p, which wiped out all my profits. Is it a 'technical conspiracy' or what?
