import historical data stock error

[cowboyss]

I downloaded historical data for AAPL and saved as .txt file
In Tools > Historical Data Manager >
I tried both NT formats / last / -5 timezone / generate day bars (and I tried unchecked)

error log - AAPL: Time stamp line 2 is smaller/equal than timestamp of previous line

how can I upload historical data?

thanks

Hello cowboyss,

Thank you for your post.

Could you please copy and paste the second line of the file you'd tried importing?

Since Yahoo only allows import of daily or larger, where can I get 1 minute bars for the full history of companies?

Hello,

There are a few 3rd party vendors who offer historical data you can import. We do not have any suggested recommendations, but I've heard good things from users regarding www.tickdata.com

Matthew,

I want to purchase a year's worth of tick data from tickdata.com. Will I be able to build volume/tick charts with that data? Also, is there still a problem with the data format from tickdata.com and NT7?

[NinjaTrader_Matthew]

The tick data you purchase can be used to build volume/tick charts with NinjaTrader.

Tickdata.com actually has a NinjaTrader formatted output you can select when you export the data.

[Vozdovac]

Thanks for your response! Does it matter if I use TickWrite Download and TickWrite On-Demand or just have them ship it to me?

[NinjaTrader_Matthew]

I'm really not sure what the difference is between those products. I'd suggest contacting them as they have very excellent support.
