This price is made by the demo. Weather Fi has no commodity price feed. The price on this page is an index the simulator builds from the linked weather index and a simulated market factor, to show how a real-asset future would trade beside a weather index future. It is not the price of lng for power on any market, and it trades and settles in virtual sUSDT only.

Where this price comes from

real weather × a simulated market

A hotter period burns more gas in power stations, so the simulated price rises with cooling degree days.

One index point moves the price by +0.345 points. The weather effect is held to ±60%.

The market factor stands in for everything else that moves a commodity - supply, storage, freight, currencies. It is a random walk the simulator steps once an hour and freezes when trading closes. The sensitivity to the weather is an assumption of this simulation, not an estimate from market data.

The reference price moves when the weather index moves and when the market factor steps. The market price follows it as simulated participants trade, and spread traders close gaps between the two contracts.

The hedged line is flat where both contracts are inside their bands: the weather is out of the result. What is left is the gap between the two markets today and the market factor, which is held here at its current -2.1% and is not hedged by a weather contract. Fills are taken at the quoted price, without the price impact of the trade.

A trade marked pair is one leg of a simulated spread trade: the other leg is in the weather index contract this price follows.

Settlement

This contract settles right after CDD-VHHH-NOV26 settles on the station record. The final price is the listing level of 100, moved by the weather effect at the final index and by the market factor as it stood when trading closed. If the weather contract is void, this one is void too and every position is refunded at cost.

Rules in short
  • The price is simulated by the demo from a real weather index and a simulated market factor. It is not a market price.
  • Long gains when the price finishes higher, short when it finishes lower. A long and a short share together always pay 1 sUSDT.
  • Outside the band 65 to 135 the contract pays as if the price 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.
  • Void, with every position refunded at cost, if the linked weather contract is void.
