Why this difference between various sources?
for terminals- terminals will show last feed data, if exchanges make changes before/at the time publishing bhavcopy,then we will get difference on website but not on terminal. other thing is on high volatile end session, last mins OI change data didn't reach to terminals/website till 3.30 pm.
for browser/links - basically b/c of above two reasons, they need to run manual module to publish this data and as there are different servers/shells for different browsers, so module/manual error in updating.
