Hi, Im currently seeing large gaps in all of my charts where no data at all is showing between the 26th March and 13th April this year at a daily view. It doesnt matter which share i look at on the UK stock market, they all have this gap, but US stocks dont. Changing to 5min or several hours view and going back i can see the data, but it goes again when i go back to daily Anyone else experiencing this?
