What this tool helps you investigate
Use the futures long-short workspace to compare consecutive interval changes for a selected contract. Its table and chart modes show how price, OI and volume evolve during the session.
The labels describe price-and-OI combinations. They are not the participant long/short contract report: use participant-wise OI when the question is which group holds the exposure.
Read the workspace
Choose the instrument, contract and observation window before interpreting the results. Read the source timestamp and any empty-data message in the live tool.
How to use Futures long-short intervals
- Choose the asset, instrument, expiry and historical or live session.
- Select the interval and confirm the row timestamps.
- Read price change and OI change together before interpreting the buildup label.
- Switch to charts to compare the selected price, OI or volume series over time.
Understand the measurements
| Measurement | How to read it |
|---|---|
| Interval row | One sampled interval compared with the preceding observation. |
| Long buildup | Price rises while OI expands. |
| Short covering | Price rises while OI contracts. |
| Session-high/low tags | D.HB and D.LB mark new session high or low behaviour in the available observations. |
A worked example
A rise from 100 to 101 with OI falling from 10,000 to 9,800 describes a price rise with 2% OI contraction. The common label is short covering. It does not show the FII long-short ratio or identify which participant closed.
This example explains the calculation or reading process. It is not a current market observation or a trade recommendation.
Checks before drawing a conclusion
- Match the interval and contract before comparing rows.
- Do not confuse this price/OI classification with participant net positions.
- Missing observations and rollover can change the apparent interval behaviour.
