Historical Tick data for 15-30 days


I’m looking to get tick data for my FnO algo. The one minute chart which i used to back test have a deviation to expected results when executed in real time. So I want more accurate data. I am looking for probably 15-30 days of historical tick data. Is there any source online where I can download or buy ?

Thanks in Advance


We can’t get historical data of any past (week/month) expiry for Historical API calls so, You can contact Global Datafeeds for this.
