Trade GDD-VIDP-NOV26

Long gains if GDD finishes above the level you pay for.

Virtual sUSDT only. No monetary value.

Rules in short
  • Long gains when the index finishes higher, short when it finishes lower. A long and a short share together always pay 1 sUSDT.
  • Outside the band 260 to 400 the contract pays as if the index had finished on the edge.
  • You pay in full when you buy. What you paid is the most you can lose: no margin, no liquidation.
  • You can sell back to the market maker at any time before trading closes, when the last day of the period begins.
  • Void, with every position refunded at cost, if any day of the period cannot settle on the record.
