Fetch historical tick data

Hi,

I try fetching tick data for a period, even for a day, and it gives me a "hasMore = true".

1) What does that mean? Is it possible to continue fetching from there or should I re-define the request using a smaller period (something like an hour)?

If I try to break a bigger period into smaller ones of one hour each the server says I exceeded the amount of requests allowed.

2) What is the maximum limit of requests?

3) How can I fetch a long period - like a year - of tick data then?

What is the best way to fetch tick data?

Many thanks,

Douglas.
