I have noticed a number of times share prices shown on charts mainly at weekends that are a factor of 2 or 3 outside the prior days trading price. This messes up the graphs and makes it much more difficult to look at data as well as it just being wrong. Come the next trading period the figure will correct back to a more normal range. What is driving these prices like TUI shares trading on Friday at 380p at close of play on the london stock exchange website. These are showing at around 1100p for the whole of friday's data. This is not the first stock either.
