Choose a data form to see the format choices available for it.
Once payment is in, we will send across final formatting options for you to choose from and then add you to our jobs list for processing. See below for what questions we will ask.
One-off data dump:
- Delivery Months: FHKNUX (Jan, Mar, May, Jul, Sep, Nov)
- Delimiter: comma, i.e. .csv .txt - ASCII. Or choose another delimiter such as semi-colon, space or tab
- Filename: Discrete names created from the symbol root, the year and delivery month code. For example GCN2026F is the January 2026 contract for Corn-TGE.
- Filename Alternatives: Choose from the following if you require compatibility elsewhere: CSI: JC4
- Column Order: date, time, open, high, low, close, volume
- Extra Columns [optional]: Prior to 22 Aug 2011 there was no such thing as intraday volume. Back then traders would use ‘tick count’ as a proxy volume. It counted the number of ‘wobbles’ in the intraday period. This was the only way to try to determine volume. If you feel it would be useful, we can include this metric, usually another column before trade volume.
