Ok, I got it, You mean even in the change in 'Timestamp' cause it to send the data. Because in the above screenshot only the 'Timestamp' field change. But I think that the timestamp generated only when there is a change in other fields.
thnks sujith..
Yes I want to get the data, when there is any change in market. But whats the point in getting repeated data even when there is no change in market.
For ur info, the data in above screenshot is of AJANTPHARM18OCTFUT.
for that u have to create new app by spending 2000 credits, and once the app is created is created you have to get historical api option under that app for which you have to spend again more 2000 credits
