Just as an example, if you want to sell shares in excess of the market size (which is 10,000 shares in SYN - check the market size on the share page in LSE, and apologies to those who I am teaching to suck eggs), they can offer you a price well below the going rate by dropping the bid price. Lots of people sell shares at 'market rate' rather than at a limit and can get caught by this 'legitimate' trick. You will see the spread altering all the time on this share.
