📠Settlement

Users trading in MetaOracle will encounter two types of settlement: waiting for the event to end and then the platform settlement, or selling the shares to another user.

Definition 9: The $\mathit{OI}$ of user $\mathit{A}$ in a given static market $\mathit{E_n}$ is $\mathit{U_AOI(E_n)}$, the predicted probability $\mathit{P(E_n)}$ at the end of the market prediction, and the predicted reward multiplier $\mathit{M(E_n)}$. After the final result of the market event is determined and User $\mathit{A}$ chooses to settle on the platform, the $\mathit{PnL}$ without considering the settlement fee is $\mathit{U_APnL_{E_n}}$.

$$\mathit{U_APnL_{E_n}=U_AOI(E_n)×\frac{1-P(E_n)}{P(E_n)}=U_AOI(E_n)×(M(En)-1)}$$

Definition 10: Given the $\mathit{OI}$ of user $\mathit{A}$ in a particular dynamic market $\mathit{E_n}$ is $\mathit{U_AOI(E_n)}$, the predicted probability $\mathit{P_d(E_n)}$, and the predicted reward multiplier $\mathit{M_d(E_n)}$. After the final result of the market event is determined and user $\mathit{A}$ chooses to settle on the platform, the $\mathit{PnL}$ without considering the settlement fee is $\mathit{U_APnL_{E_n}}$.

$$\mathit{U_APnL_{E_n}=U_AOI(E_n)×\frac{1-P_d(E_n)}{P_d(E_n)}=U_AOI(E_n)×(M_d(En)-1)}$$

Definition 11: The $\mathit{OI}$ of user $\mathit{A}$ in a given dynamic market $\mathit{E_n}$ is $\mathit{U_AOI(E_n)}$, the predicted probability $\mathit{P_{d}^{T_0}(E_n)}$, and the predicted reward multiplier $\mathit{M_{d}^{T_0}(E_n)}$. At a certain T1 moment before the end of the market, the predicted probability $\mathit{P_{d}^{T_1}(E_n)}$ and the predicted reward multiplier $\mathit{M_{d}^{T_1}(E_n)}$. At this point, user $\mathit{A}$ sells his share to another user by choosing the platform settlement, and the $\mathit{PnL}$ without considering the settlement fee is $\mathit{U_APnL_{E_n}}$.

$$\mathit{U_APnL_{E_n}=U_AOI(E_n)×\frac{P_{d}^{T_1}(E_n)-P_{d}^{T_0}(E_n)}{P_{d}^{T_0}(E_n)}=U_AOI(E_n)×\frac{M_{d}^{T_0}(E_n)-M_{d}^{T_1}(E_n)}{M_{d}^{T_1}(E_n)}}$$

2.4.1 Settlement Fee

MetaOracle charges users a settlement fee.

Definition 11: For any user $\mathit{A}$ who gets a $\mathit{PnL}$ of $\mathit{U_APnL_{E_n}}$ without considering the settlement fee, a fixed percentage of the settlement fee - $\mathit{U_ALF_{E_n}}$ is charged, i.e.

$$\mathit{U_{A}LF_{E_n}=U_{A}PnL_{E_n}\times Fee\%}$$
