Buy historical tick data

[nightriderx]

I am looking to buy several months of historical tick data at level 1 for a few stocks. Can you please recommend a reliable vendor? Also, what formats will nt7 accept of such data and how do I go about loading it properly?
thx

Hello,

Thank you for your post.

In order to import data into NinjaTrader data must be in a .txt text format. I have provided a link below to our Help Guide that goes over Importing Data.

Unfortunately I am not aware of a vendor that offers this data however other users may have additional input on vendors they have used for purchasing data.

Please let me know if I may be of further assistance.
