Description of problem and/or code sample that reproduces the issue

When i read a symbol data from Tickstore database it does not show the complete data even though my date_range=None , so i should get entire series. library.read("symbol")

Also i checked using max_date the last index of the symbol, i could see the last index entry is greater than what i see while reading the symbol. Is there a limit to number of ticks which read fetches ?

Could you please post your sample code? I had a similar issue, but setting a date range resolved it for me.

You need to pass a date_range in that isn't None. By default it will only read a month of data if you don't specify what you want in TickStore - as the data can be very large indeed...
