VIX

VIX 反映市场对未来 30 天波动率的预期。

算法核心步骤

选取剩余到期日大于 7 天的最近到期合约作为近月合约，次近到期合约作为次近月合约。
计算近月和次近月波动率：

$\sigma ^ { 2 } = \frac { 2 } { T } \sum _ { i } \frac { \Delta K _ { i } } { K _ { i } ^ { 2 } } e ^ { R T } P ( K _ { i } ) - \frac { 1 } { T } \left[ \frac { F } { K _ { 0 } } - 1 \right] ^ { 2 }$

其中：

$T=\frac{N_{T}}{N_{365}}$

N_T 为合约剩余到期时间（以分钟计），N₃₆₅ 是一年的分钟数（固定值）。

R：无风险利率。

S：认购期权价格与认沽期权价格相差最小的执行价。

F：S + e^RT × [认购期权价格(S) − 认沽期权价格(S)]。

K_i：由小到大排列的所有执行价（i = 1, 2, 3, …）。

K₀：小于 F 且最接近 F 的执行价。

ΔK_i：第 i 个执行价对应的执行价间隔，通常为 (K_i+1 − K_i−1) / 2。

P(K_i)：当 K_i < K₀ 时，取 K_i 对应的认沽期权价格；当 K_i > K₀ 时，取 K_i 对应的认购期权价格；当 K_i = K₀ 时，取 K_i 对应的认沽期权与认购期权价格的平均值。
期权价格选择规则
1. 当日有成交时，取最新价。
2. 当日无成交时，取昨结算价。
3. 合约进入熔断状态时，如有虚拟成交价格，则取虚拟成交价格；否则取熔断前确定的价格。
如果某个期权没有以上任何一种价格，则不将其纳入波动率计算。
计算 VIX：

$VIX = 100 * \sqrt {\{ T _ { 1 } \sigma _ { 1 } ^ { 2 } \bigg[\frac { N _ { T 2 } - N _ { 3 0 } } { N _ { T 2 } - N _ { T 1 } } \bigg] + T _ { 2 } \sigma _ { 2 } ^ { 2 } \bigg[\frac { N _ { 3 0 } - N _ { T 1 } } { N _ { T 2 } - N _ { T 1 } }\bigg] \} \frac { N _ { 365} } { N _ { 3 0 } }}$

其中：

σ₁、σ₂ 分别为近月和次近月波动率。

N_T1、N_T2 分别为近月和次近月合约的剩余到期时间（以分钟计）。

N₃₀、N₃₆₅ 分别为 30 天和一年的分钟数。

T₁ = N_T1 / N₃₆₅，T₂ = N_T2 / N₃₆₅。

加权指数

该品种所有月份合约的最新价按照持仓量占比加权计算，得到加权指数合约的价格。

Markets

View real-time market data for instruments.

Path: Menu → Trade → Markets

Window Interaction

Double-click Bid, Ask, B.size, or A.size to open the corresponding order entry window. By default, the InfiniTrader window opens.

To change the default order entry window, go to Systems → Settings → General Settings, then select the order entry window opened by double-clicking market data.
Double-click anywhere else in Markets to open Market Charts for the selected instrument.
When Link is enabled in an order entry window or chart window, clicking an instrument in Markets syncs the instrument details and Account to the linked window.
Price linking: When you click a price cell, such as Bid, Ask, or Last, the value in that cell is also passed to the linked window. The price passed to the window depends on the price cell under the mouse pointer.

Market Information

Status: Shows the current trading status of the instrument. During normal market hours, the status is Open. Other statuses include Pre-Trade, Halted, AuctionOrdering, and Closed.
Update Time: Shows the time when the most recent market data update for the instrument was received, not the current time. If market data is delayed because of a network issue, check this value to determine whether the data is updating.
Fee/Margin: Shows the fee and margin rates returned by the upstream system. Click a blank cell in this column to query the rates.

Continuous and Dominant Contracts

A continuous contract uses a code such as agMain, where ag is the product code.

A dominant contract is identified by an M suffix, such as ag2102M.

At the close of each trading day, the contract with both high Open Interest and Volume is designated as the dominant contract. The dominant contract is reviewed and may be switched after each trading-day close.

Watchlist

From the context menu in Markets, add the current instrument to a watchlist group or open the Watchlist window. See Watchlist for details.

Hotkey Order Entry

Enable Hotkey in the upper-right corner to place orders for instruments using keyboard shortcuts. See Settings for details.

Hotkeys are available only when the Markets window is selected and Hotkey is enabled. A selected embedded window has a blue border.
The Markets window does not provide open/close or quantity controls. The default open/close setting is Auto(DayTrade First), and the default quantity is 1. These defaults cannot be changed. Use hotkeys to switch the open/close action.

VIX

VIX reflects the market's expectation of volatility over the next 30 days.

Calculation

Select the nearest-expiry contract with more than seven days remaining as the near-term contract, and the next expiry as the next-term contract.
Calculate the near-term and next-term variances:

$\sigma ^ { 2 } = \frac { 2 } { T } \sum _ { i } \frac { \Delta K _ { i } } { K _ { i } ^ { 2 } } e ^ { R T } P ( K _ { i } ) - \frac { 1 } { T } \left[ \frac { F } { K _ { 0 } } - 1 \right] ^ { 2 }$

Where:

$T=\frac{N_{T}}{N_{365}}$

N_T is the time remaining to expiration, in minutes. N₃₆₅ is the number of minutes in one year (a fixed value).

R: Risk-free interest rate.

S: Strike price with the smallest difference between the call and put prices.

F: S + e^RT × [call price(S) − put price(S)].

K_i: All strike prices in ascending order (i = 1, 2, 3, …).

K₀: Strike price immediately below and closest to F.

ΔK_i: Strike interval for the ith strike, generally calculated as (K_i+1 − K_i−1) / 2.

P(K_i): The put price at K_i when K_i < K₀; the call price at K_i when K_i > K₀; or the average of the put and call prices at K_i when K_i = K₀.
Option price selection
1. If the option traded today, use the Last price.
2. If the option did not trade today, use the previous settlement price.
3. If the contract is under a volatility interruption, use the indicative execution price when available. Otherwise, use the price determined before the interruption.
Exclude an option from the variance calculation if none of these prices is available.
Calculate VIX:

$VIX = 100 * \sqrt {\{ T _ { 1 } \sigma _ { 1 } ^ { 2 } \bigg[\frac { N _ { T 2 } - N _ { 3 0 } } { N _ { T 2 } - N _ { T 1 } } \bigg] + T _ { 2 } \sigma _ { 2 } ^ { 2 } \bigg[\frac { N _ { 3 0 } - N _ { T 1 } } { N _ { T 2 } - N _ { T 1 } }\bigg] \} \frac { N _ { 365} } { N _ { 3 0 } }}$

Where:

σ₁ and σ₂ are the near-term and next-term variances, respectively.

N_T1 and N_T2 are the times remaining to expiration for the near-term and next-term contracts, respectively, in minutes.

N₃₀ and N₃₆₅ are the numbers of minutes in 30 days and one year, respectively.

T₁ = N_T1 / N₃₆₅ and T₂ = N_T2 / N₃₆₅.

Weighted Index

The Weighted Index price is calculated from the Last prices of all contract months for the product, weighted by each contract's share of total Open Interest.
