- Portara is the approved historical data provider for NinjaTrader
- Usually tick data, especially Level 1 tick data, which contains the bids and asks, is very expensive and extremely large in size.
- To help NinjaTrader users, Portara has created highly discounted historical data sets that you can import directly into NinjaTrader without headaches. Full import step-by-step instructions are given.

Tick – Trades Only (No Bids & Asks) Data
Only the historical trades (known as ‘last’ in NinjaTrader) are purchased. The data is a less expensive than Level 1 tick and also is 10 to 100x smaller in size. It is easy to manipulate and much faster to import into NinjaTrader. NOTE: If you can manage without the bids and asks in your strategy or for your ‘NinjaTrader Playback’ requirements, then this route will be best.
- NinjaTrader is now capable of using tick – trades only data for Market Replay and Playback regardless of the old note in the NinjaTrader help files saying the opposite. See the video below for details of how to do that:
- Because there are no bids and asks in Tick – Trades Only data, NinjaTrader simulates the bids and asks when in Market Replay Playback mode.
Watch the video below on how to transform your ‘historical data’ into ‘market replay’ data within NinjaTrader and then use that ‘market replay’ data in Playback:

- SPECIAL DEAL FOR NINJATRADER USERS
- As an example, ES in its raw form is 500 GB (1/2TB) in size. It would be impossible to read this into NinjaTrader due to its enormous size.
- To help, Portara will parse through the Level 1 CQG data sets, extracting the bid and ask at the time of each trade and placing it into the required NinjaTrader format.
- This means that you do not have to purchase the Level 1 data at all from us. This saves you thousands of dollars and weeks of unnecessary programming and parsing time.
You can also import historical tick data to be used with ‘Tick Replay’, which includes the current bid and ask prices associated with the last price of that tick (not to be confused with Playback “Market Replay” data which CANNOT import manually).
Tick – Including Trades Bids & Asks (with Millisecond Granularity)
synonymous with Tick Replay Format (with Millisecond Granularity)
The format is:
yyyyMMdd HHmmss fffffff;last price; bid price; ask price;volume
The algorithm for bids and asks needs to be as follows otherwise the data will NOT import in:
- Bid price must remain below or equal to trade price
- Ask price must remain above or equal to trade price.
- Portara deals with this algorithm so your data will read successfully into the NT platform.
