When I log on, my historical data is kept on a 1 min chart, but when i change it to a tick or secound chart it i lose all my recorded data, it even happens if i switch from a 1 min chart to a 2min chart. again i lose all date that has been recorded on a 1min chart.....
Not sure what I have done, but this as only happen the last 2 days, before this, it was working fine any help ?
Thanks
