Trading
Long and Short
Every position has two tokens: Long and Short.
The Long price is the position's Attention Share. A position with 18% Attention Share has a Long price of $0.18. If its share rises to 25%, the Long price rises to $0.25.
The Short price is the complement. Long price and Short price always sum to $1.00. A Long price of $0.18 means a Short price of $0.82.
Buy Long and you profit when Attention Share rises. Buy Short and you profit when it falls. See Tokens for how Long and Short tokens work.

How trades move prices
All prices in a Sentidex market sum to $1.00. Every position holds a share of a whole.
Buying a position increases demand for it, and demand raises its price. When one price rises, the others must fall to keep the total at $1.00. Selling works in reverse.
The AMM
Sentidex prices every market through a custom-built automated market maker, designed from scratch for on-chain multi-outcome trading. You trade directly against it at any time, with no counterparty required. The design is novel: purpose-built for markets where every position competes for a share of a fixed total, pricing every outcome continuously without requiring seed liquidity.
No liquidations or funding rate
A position on Sentidex works like a prediction market position. There is no funding rate charged for holding it and no liquidation risk. Your maximum loss is the price you paid for the position, and it stays open for as long as you choose to hold it.
Closing a position
Sell Long or Short tokens back to the AMM at any time. The AMM quotes a price for every position continuously, so there is always a price to enter or exit. There is no expiry and no settlement date.
