Overview Edit
Welcome to JU API documentation. JU provides REST and Websocket APIs to suit your trading needs.
API Resources and Support Edit
Java libraries
A lightweight Java code library: Java SDK
JavaScript SDK
This JavaScript SDK provides access to various endpoints for interacting with the JU platform: JavaScript SDK
REST API Edit
production environment: https://api.jucoin.com
https://api.jucoin.io(backup 1)
https://api.jucoin.live(backup 2)
Basic information of the interface Edit
Due to reasons such as high latency and poor stability, it is not recommended to access the API through a proxy.
GET request parameters are placed in query Params, POST request parameters are placed in request body
Please set the request header information to：Content-Type=application/json
For requests that start other than /public, the request message needs to be signed
Frequency Limiting Rules Edit
Some interfaces will have limited flow control (the corresponding interface will have a limited flow description). The flow limit is mainly divided into gateway flow limit and WAF flow limit.
If the interface request triggers the gateway flow limit, 429 will be returned, indicating that the access frequency exceeds the limit, and the IP or apiKey will be blocked.
Gateway flow limiting is divided into IP and apiKey flow limiting.
Example description of IP flow limit: 100/s/ip, indicating the limit of the number of requests per second for this interface per IP.
apiKey current limit example description: 50/s/apiKey, indicating the limit of the number of requests per second for the interface per apiKey.
Signature Instructions Edit
Since JU needs to provide some open interfaces for third-party platforms，therefore, the issue of data security needs to be considered. Such as whether the data has been tampered with, whether the data is outdated, whether the data can be submitted repeatedly, and the access frequency of the interface, and whether data has been tampered with is the most important issue.
-
Please apply for appkey and secretkey in the user center first, each user’s appkey and secretkey are different.
-
Add timestamp, its value should be the unix timestamp (milliseconds) of the time when the request is sent, and the time of the data is calculated based on this value.
-
Add signature, its value is obtained by a certain rule of signature algorithm.
-
Add recvwindow (defining the valid time of the request), the valid time is currently relatively simple and uniformly fixed at a certain value.
When a request is received by the server, the timestamp in the request is checked to ensure it falls between 2 to 60 seconds. Any request with a timestamp older than 5,000 milliseconds is considered invalid. The time window value can be set using the optional parameter: “recvWindow”. Additionally, if the server determines that the client’s timestamp is more than one second ahead of the server, the request will also be invalid. Online conditions are not always 100% reliable in terms of the timeliness of trades, dataing in varying levels of latency between your local program and the JU server. This is why we provide the “recvWindow” parameter - if you engage in high-frequency trading and require stricter transaction timeliness, you can adjust the “recvWindow” parameter to better meet your needs.
Recvwindow longer than 5 seconds is not recommended.
5、Added algorithm (signature method/algorithm), the user calculates the signature according to the protocol of the hash, and HmacSHA256 is recommended. For those protocols that are supported, see the table below.
HmacMD5、HmacSHA1、HmacSHA224、HmacSHA256(recommended)、HmacSHA384、HmacSHA512
Signature generation Edit
Take https://api.jucoin.io/v1/spot/order as an example.
The following is an example appkey and secret for placing an order using a call interface implemented by echo openssl and curl tools in the linux bash environment for demonstration purposes only:
appKey: 3976eb88-76d0-4f6e-a6b2-a57980770085
secretKey: bc6630d0231fda5cd98794f52c4998659beda290
Header part data：
validate-algorithms: HmacSHA256
validate-appkey: 3976eb88-76d0-4f6e-a6b2-a57980770085
validate-recvwindow: 5000
validate-timestamp: 1641446237201
validate-signature: 2b5eb11e18796d12d88f13dc27dbbd02c2cc51ff7059765ed9821957d82bb4d9
request data：
{
type: 'LIMIT',
timeInForce: 'GTC',
side: 'BUY',
symbol: 'btc_usdt',
price: '39000',
quantity: '2'
}
1.data part
method: UpperCase method. eg: GET, POST, DELETE, PUT
path: Concatenate all values in the order in path. The restful path in the form of /test/{var1}/{var2}/ will be spliced according to the actual parameters filled in, for example: /sign/test/bb/aa
query: Sort all key=value according to the lexicographical order of the key. Example: userName=dfdfdf&password=ggg
body:
Json: Directly by JSON string without conversion or sorting.
x-www-form-urlencoded: Sort all key=values according to the lexicographical order of keys, for example: userName=dfdfdf&password=ggg
form-data：This format is not currently supported.
If there are multiple data forms, re-splicing is performed in the order of path, query, and body to obtain the splicing value of all data.
Method example:
POST
Path example:
/v1/spot/order
The above concatenated value is recorded as path
Parameters passed query example:
symbol=btc_usdt
The above concatenated value is recorded as query
Parameters via body example
x-www-form-urlencoded:
symbol=btc_usdt&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1
The above concatenated value is recorded as body
json:
{"symbol":"btc_usdt","side":"BUY","type":"LIMIT","timeInForce":"GTC","quantity":2,"price":39000}
The above concatenated value is recorded as body
Mixed use of query and body (divided into form and json format)
query:
symbol=btc_usdt&side=BUY&type=LIMIT
The above concatenated value is recorded as query
body:
{"symbol":"btc_usdt","side":BUY,"type":"LIMIT"}
The above concatenated value is recorded as body
The most concatenated value of the entire data is spliced with method, path, query, and body by the # symbol to form #method, #path, #query, and #body, and the final spliced value is recorded as Y=#method#path#query#body. Notice：
The query has data, but the body has no data: Y=#method#path#query
query has no data, body has data: Y=#method#path#body
query has data, body has data: Y=#method#path#query#body
2.request header part After the keys are in natural ascending alphabetical order, use & to join them together as X. like:
validate-algorithms=HmacSHA256&validate-appkey=3976eb88-76d0-4f6e-a6b2-a57980770085&validate-recvwindow=5000&validate-timestamp=1641446237201
3.generate signature
Finally, the string that needs to be encrypted is recorded as original=XY
Finally, encrypt the final concatenated value according to the following method to obtain a signature.
signature=org.apache.commons.codec.digest.HmacUtils.hmacSha256Hex(secretkey, original);
Put the generated signature singature in the request header, with validate-signature as the key and singature as the value.
4.example
sample of original signature message:
validate-algorithms=HmacSHA256&validate-appkey=2063495b-85ec-41b3-a810-be84ceb78751&validate-recvwindow=60000&validate-timestamp=1666026215729#POST#/v1/spot/order#{"symbol":"JU_USDT","side":"BUY","type":"LIMIT","timeInForce":"GTC","bizType":"SPOT","price":3,"quantity":2}
sample request message:
curl --location --request POST 'https://api.jucoin.io/v1/spot/order'
--header 'accept: */*'
--header 'Content-Type: application/json'
--header 'validate-algorithms: HmacSHA256'
--header 'validate-appkey: 10c172ca-d791-4da5-91cd-e74d202dac96'
--header 'validate-recvwindow: 60000'
--header 'validate-timestamp: 1666026215729'
--header 'validate-signature: 4cb36e820f50d2e353e5e0a182dc4a955b1c26efcb4b513d81eec31dd36072ba'
--data-raw '{"symbol":"JU_USDT","side":"BUY","type":"LIMIT","timeInForce":"GTC","bizType":"SPOT","price":3,"quantity":2}'
matters needing attention:
Pay attention to checking the parameter format of Content Type, signature original message and request message

FAQ Edit
1.AUTH_ 105: The server verifies the request header parameters validate-timestamp (validTimeStamp) and validate-recvwindow (recvwindow) The following rules must be followed: dealTimeStamp (server time when the request is processed, in milliseconds) - validTimeStamp < recvwindow, otherwise AUTH_105 will be returned. To avoid this error, validate-timestamp recommends using the time when the request was sent, and it is measured in milliseconds. The validate-recvwindow is set a little larger

Limit Flow Rules
1.single symbol：10/s/ip
2.multiple symbols：10/s/ip
FILTER
Filter, defines a series of trading rules. There are different filters for different fields or entities. Here we mainly introduce the filter for the entity symbol. For symbols, there are two kinds of filters, one is a global filter, and the other is a filter customized for a certain trading pair.
PRICE FILTER
The price filter is used to check the validity of the price parameter in the order. Contains the following three parts:
1.min Defines the minimum allowable price in the order
2.max Defines the maximum price allowed in the order
3.tickSize Defines the step interval of price in the order, that is, price must be equal to minPrice+(integer multiple of tickSize)
Each of the above items can be null, when it is null, it means that this item is no longer restricted
The logical pseudocode is as follows:
- price >= min
- price <= max
- (price-minPrice) % tickSize == 0
QUANTITY FILTER
The logic is similar to PRICE FILTER ,but for the order quantity.
It contains three parts:
1.min minimum allowed
2.max maximum allowed
3.tickSize Step interval, that is, quantity must be equal to minQuantity+(integer multiple of tickSize)
Each of the above items can be null, when it is null, it means that this item is no longer restricted
The logical pseudocode is as follows:
- quantity>= min
- quantity<= max
- (quantity-minQuantity)% tickSize == 0
QUOTE_QTY FILTER
Limit the amount of the order
It internally defines the minimum allowable value-min
When min is null, the order is not limited
Otherwise the restriction rules are as follows:
1.For orders of the LIMIT type,must meet the following conditions: price*quantity>=min
2.For orders of the MARKET type and BUY type,must meet the following conditions: quoteQty>=min,(quoteQty,The required amount when placing an order of MARKET type by amount)
PROTECTION_LIMIT FILTER
There are price protection restrictions for orders whose order type (orderType) is LIMIT, including the following four parts：
1.buyMaxDeviation: The maximum deviation of the buy order, determine the minimum buy order price based on this value and the latest transaction price
2.buyPriceLimitCoefficient: The buy limit coefficient, determine the maximum buy order price based on this value and the latest transaction price
3.sellMaxDeviation: The maximum deviation of the sell order, determine the maximum sell order price based on this value and the latest transaction price
4.sellPriceLimitCoefficient: The sell limit coefficient, determine the minimum sell order price based on this value and the latest transaction price
If there is no latest transaction price, there will be no restrictions, or if the above parameters are null, the corresponding direction type orders will not be restricted.
In order to pass the limit price protection, the order price must meet the following conditions (latestPrice is the latest transaction price)
buy order: price >= latestPrice-latestPrice*buyMaxDeviation && price <= latestPrice+latestPrice*buyPriceLimitCoefficient
sell order: price <= latestPrice+latestPrice*sellMaxDeviation && price >= latestPrice-latestPrice*sellPriceLimitCoefficient
PROTECTION_MARKET FILTER
There is a price limit protection mechanism for orders of the order type MARKET, which internally specifies the maximum deviation rate(maxDeviation).
For market type orders, the market price must meet the following conditions for the order to pass(sellBestPrice sell one price，buyBestPrice buy one price，latestPrice The latest transaction price, these data are obtained through historical transaction data)
buy order: latestPrice + latestPrice* maxDeviation >= sellBestPrice
sell order: latestPrice - latestPrice* maxDeviation <= buyBestPrice
For the above situation maxDeviation,latestPrice,sellBestPrice,buyBestPrice
All may be empty or there is no latest transaction price, buy one price, sell one price, there is no limit
PROTECTION_ONLINE FILTER
Limit the price of orders of the MARKET type within the specified time range after the opening
The maximum price multiple is defined inside this filter(maxPriceMultiple)，duration(durationSeconds)。
Limitation logic: when it is within the durationSeconds time range after the opening of the symbol, Orders with an order type of LIMIT must meet the following conditions to pass
price<=openPrice*maxPriceMultiple,（openPrice is the opening price）.
There are no restrictions on other types of orders or orders outside the opening time frame.
For maxPriceMultiple, durationSeconds can be null, when they are null, no opening protection limit is applied.

Orderbook manage Edit
How to manage a local order book correctly
1.Open a stream to wss://stream.ju.com/public , depth_update@btc_usdt
2.Buffer the events you receive from the stream.
3.Get a depth snapshot from https://api.jucoin.io/v1/spot/public/depth?symbol=btc_usdt&limit=500
4.Drop any event where i is <= lastUpdateId in the snapshot.
5.The first processed event should have fi <= lastUpdateId+1 AND i >= lastUpdateId+1.
6.While listening to the stream, each new event’s fi should be equal to the previous event’s i+1.
7.The data in each event is the absolute quantity for a price level.
8.If the quantity is 0, remove the price level.
9.Receiving an event that removes a price level that is not in your local order book can happen and is normal.
Note: Due to depth snapshots having a limit on the number of price levels, a price level outside of the initial snapshot that doesn’t have a quantity change won’t have an update in the Diff. Depth Stream. Consequently, those price levels will not be visible in the local order book even when applying all updates from the Diff. Depth Stream correctly and cause the local order book to have some slight differences with the real order book. However, for most use cases the depth limit of 500 is enough to understand the market and trade effectively.

REST API Edit
生产环境: https://api.jucoin.com

接口的基本信息 Edit
鉴于延迟高和稳定性差等原因，不建议通过代理的方式访问API。
GET请求参数放入query Params中，POST请求参数放入request body中
请求头信息请设置为：Content-Type=application/json
对于/public以外开头的请求，需要对请求报文进行签名
限频规则 Edit
部分接口会有限流控制(对应接口下会有限流说明)，限流主要分为网关限流和WAF限流。
若接口请求触发了网关限流则会返回429，表示警告访问频次超限，即将被封IP或者apiKey。
网关限流分为针对IP和apiKey限流。
IP限流示例说明：100/s/ip，表示每个IP每秒该接口请求次数限制。
apiKey限流示例说明：50/s/apiKey，表示每个apiKey每秒该接口请求次数限制。
签名说明 Edit
由于JU需要为第三方平台提供一些开放性的接口，所以需要接口的数据安全问题，比如数据是否被篡改，数据是否已过时，数据是否可以重复提交，接口在某个时间内访问频率等问题。其中数据是否被篡改是最重要的。
1、先通过用户中心申请appkey和secretkey，针对不同的调用，提供不同的appkey和secretkey
2、加入timestamp(时间戳)，其值应当是请求发送时刻的unix时间戳(毫秒)，数据的有郊时间根据此值来计算。
3、加入signature(数据签名)，所有数据的签名信息。
4、加入recvwindow(自定义请求有效时间)，有效时间目前相对简单统一固定为某个值。
服务器收到请求时会判断请求中的时间戳，最长60秒，最小为2秒，如果是5000毫秒之前发出的，则请求会被认为无效。这个时间窗口值可以通过发送可选参数recvWindow来设置。 另外，如果服务器计算得出客户端时间戳在服务器时间的‘未来’一秒以上，也会拒绝请求。 关于交易时效性 互联网状况并不100%可靠，不可完全依赖,因此你的程序本地到JU服务器的时延会有抖动. 这是我们设置recvwindow的目的所在，如果你从事高频交易，对交易时效性有较高的要求，可以灵活设置recvwindow以达到你的要求。
不推荐使用5秒以上的recvwindow
5、加入algorithms (签名方法/算法)，用户计算签名是基于哈希的协议，推荐使用HmacSHA256。具体支持那些协议，请参见下面表格中所列出。
HmacMD5、HmacSHA1、HmacSHA224、HmacSHA256(推荐)、HmacSHA384、HmacSHA512
签名生成 Edit
以https://api.jucoin.io/v1/spot/order为例。
以下是在linux bash环境下使用 echo openssl 和curl工具实现的一个调用接口下单的示例 appkey、secret仅供示范：
appKey: 3976eb88-76d0-4f6e-a6b2-a57980770085
secretKey: bc6630d0231fda5cd98794f52c4998659beda290
Header部分数据：
validate-algorithms: HmacSHA256
validate-appkey: 3976eb88-76d0-4f6e-a6b2-a57980770085
validate-recvwindow: 5000
validate-timestamp: 1641446237201
validate-signature: 2b5eb11e18796d12d88f13dc27dbbd02c2cc51ff7059765ed9821957d82bb4d9
请求数据：
{
type: 'LIMIT',
timeInForce: 'GTC',
side: 'BUY',
symbol: 'btc_usdt',
price: '39000',
quantity: '2'
}
1、数据部分
method: 大写的请求方法，例如：GET、POST、DELETE、PUT
path: 按照path中顺序将所有value进行拼接。形如/test/{var1}/{var2}/的restful路径将按填入的实际参数后路径拼接，示例：/sign/test/bb/aa
query: 按照key的字典序排序，将所有key=value进行拼接。示例：userName=dfdfdf&password=ggg
body:
Json: 直接按JSON字符串不做转换或排序操作。
x-www-form-urlencoded: 按照key的字典序排序，将所有key=value进行拼接，示例:userName=dfdfdf&password=ggg
form-data：此格式暂不支持。
如果存在多种数据形式，则按照path、query、body的顺序进行再拼接，得到所有数据的拼接值。
方法method示例：
POST
路径path示例:
/v1/spot/order
上述拼接值记作为path
参数通过query示例:
symbol=btc_usdt
上述值拼接记作query
参数通过body示例
x-www-form-urlencoded:
symbol=btc_usdt&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1
上述值拼接记作body
json:
{"symbol":"btc_usdt","side":"BUY","type":"LIMIT","timeInForce":"GTC","quantity":2,"price":39000}
上述值拼接记作body
混合使用query与body(分为表单与json两种格式)
query:
symbol=btc_usdt&side=BUY&type=LIMIT
上述拼接值记作query
body:
{"symbol":"btc_usdt","side":BUY,"type":"LIMIT"}
上述拼接值记作body
整个数据最且拼接值由#符号分别与method、path、query、body进行拼接成#method、#path、#query、#body，最终拼接值记作为Y=#method#path#query#body。 注意：
query有数据，body无数据：Y=#method#path#query
query无数据，body有数据：Y=#method#path#body
query有数据，body有数据：Y=#method#path#query#body
2、请求头部分 将key按照字母自然升序后，使用&方式拼接在一起，作为X。如：
validate-algorithms=HmacSHA256&validate-appkey=3976eb88-76d0-4f6e-a6b2-a57980770085&validate-recvwindow=5000&validate-timestamp=1641446237201
3、生成签名
最终把需要进行加密的字符串，记作为original=XY
最后将最终拼接值按照如下方法进行加密得到签名。
signature=org.apache.commons.codec.digest.HmacUtils.hmacSha256Hex(secretkey, original);
将生成的签名singature放到请求头中，以validate-signature为Key，以singature为值。
4、样例
签名原始报文样例：
validate-algorithms=HmacSHA256&validate-appkey=2063495b-85ec-41b3-a810-be84ceb78751&validate-recvwindow=60000&validate-timestamp=1666026215729#POST#/v1/spot/order#{"symbol":"JU_USDT","side":"BUY","type":"LIMIT","timeInForce":"GTC","bizType":"SPOT","price":3,"quantity":2}
请求报文样例：
curl --location --request POST 'https://api.jucoin.io/v1/spot/order'
--header 'accept: */*'
--header 'Content-Type: application/json'
--header 'validate-algorithms: HmacSHA256'
--header 'validate-appkey: 10c172ca-d791-4da5-91cd-e74d202dac96'
--header 'validate-recvwindow: 60000'
--header 'validate-timestamp: 1666026215729'
--header 'validate-signature: 4cb36e820f50d2e353e5e0a182dc4a955b1c26efcb4b513d81eec31dd36072ba'
--data-raw '{"symbol":"JU_USDT","side":"BUY","type":"LIMIT","timeInForce":"GTC","bizType":"SPOT","price":3,"quantity":2}'

注意检查 Content-Type、签名原始报文中的参数格式、请求报文中的参数格式

FAQ Edit
1.AUTH_105：服务器在校验请求头参数validate-timestamp(validTimeStamp)、validate-recvwindow（recvwindow）时， 需要符合以下规则：dealTimeStamp（请求被处理时服务器时间,单位毫秒）- validTimeStamp < recvwindow ，否则就会返回AUTH_105，为了避免此错误，建议validate-timestamp 设置为请求发出的时间，以毫秒为单位，validate-recvwindow设置的大一点

过滤器
过滤器，即Filter，定义了一系列交易规则。针对不同的领域或者实体有不同的过滤器，这里主要介绍针对symbol这个实体的过滤器。 对于symbol来说，有两种过滤器，一种是全局过滤器，一种是针对某个交易对定制的过滤器。
价格过滤器 PRICE FILTER
价格过滤器 用于检测订单中 price 参数的合法性。包含以下三个部分:
1.min 定义了订单中price允许的最小值
2.max 定义了订单中price允许的最大值
3.tickSize 定义了订单中price的步进间隔，即price必须等于minPrice+(tickSize的整数倍)
以上每一项均可为null，为null时代表这一项不再做限制
逻辑伪代码如下:
- price >= min
- price <= max
- (price-minPrice) % tickSize == 0
数量过滤器 QUANTITY FILTER
其逻辑和PRICE FILTER 类似，不过针对的是订单数量。
其内部包含三个部分
1.min 允许的最小值
2.max 允许的最大值
3.tickSize 步进间隔，即quantity必须等于minQuantity+(tickSize的整数倍)
以上每一项均可为null，为null时代表这一项不再做限制
逻辑伪代码如下:
- quantity>= min
- quantity<= max
- (quantity-minQuantity)% tickSize == 0
金额过滤器 QUOTE_QTY FILTER
对于订单的金额做限制
其内部定义了min允许的最小值
当min为null时，订单不做限制
否则限制规则如下：
1.对于限价LIMIT类型的订单，需满足 price*quantity>=min
2.对于市价MARKET类型并且是购买类型(orderSide=BUY)订单，需满足quoteQty>=min,(quoteQty,市价按金额下单时必填的金额)
开盘保护过滤器 PROTECTION_ONLINE FILTER
对处于开盘之后指定的时间范围内，对于限价类型的订单的价格进行限制
该过滤器内部定义了最大价格倍数(maxPriceMultiple)，持续时间(durationSeconds)。
限制逻辑:当处于交易对开盘后durationSeconds时间范围内，订单类型为限价类（LIMIT）的订单
须满足订单价格price<=openPrice*maxPriceMultiple,才会通过（openPrice为开盘价）。
其他类型的订单或者不在开盘时间范围内的订单不做限制。
对于maxPriceMultiple,durationSeconds均可为null,为null时，不做开盘保护限制。
限价保护过滤器 PROTECTION_LIMIT FILTER
对于订单类型(orderType)为LIMIT(限价) 类型的订单具有价格保护限制，包含以下四个部分
1.buyMaxDeviation: 买单最大偏离度，根据该值和最新成交价确定买单价格最小值
2.buyPriceLimitCoefficient: 买单限制系数，根据该值和最新成交价确定买单价格最大值
3.sellMaxDeviation: 卖单最大偏离度，根据该值和最新成交价确定卖单价格最大值
4.sellPriceLimitCoefficient: 卖单限制系数，根据该值和最新成交价确定卖单价格最小值
若没有最新成交价则不做限制，或者以上参数为null,则对应方向类型订单不做限制
为了通过限价保护，订单price必须满足以下条件(latestPrice为最新成交价)
买单: price >= latestPrice-latestPrice*buyMaxDeviation && price <= latestPrice+latestPrice*buyPriceLimitCoefficient
卖单: price <= latestPrice+latestPrice*sellMaxDeviation && price >= latestPrice-latestPrice*sellPriceLimitCoefficient
市价保护过滤器 PROTECTION_MARKET FILTER
对于订单类型为MARKET的订单具有价格限制保护机制，其内部规定了maxDeviation最大偏差率。
对于市价类型订单，市场价格须满足以下条件，订单才会通过(sellBestPrice 卖一价格，buyBestPrice 买一价格，latestPrice 最新成交价,这些数据均通过历史成交数据获得)
买单: latestPrice + latestPrice* maxDeviation >= sellBestPrice
卖单: latestPrice - latestPrice* maxDeviation <= buyBestPrice
对于以上情况maxDeviation，latestPrice，sellBestPrice ，buyBestPrice
均有可能为空或者没有最新成交价，买一价格，卖一价格，则不做限制

Orderbook 维护 Edit
如何正确在本地维护一个orderbook副本
1.订阅 wss://stream.ju.com/public，depth_update@btc_usdt
2.开始缓存收到的更新。同一个价位，后收到的更新覆盖前面的。
3.访问Rest接口 https://api.jucoin.io/v1/spot/public/depth?symbol=btc_usdt&limit=500 获得一个500档的深度快照
4.将目前缓存到的信息中i <= 步骤3中获取到的快照中的lastUpdateId的部分丢弃(丢弃更早的信息，已经过期)。
5.将深度快照中的内容更新到本地orderbook副本中，并从websocket接收到的第一个fi <= lastUpdateId+1 且 i >= lastUpdateId+1 的event开始继续更新本地副本。
6.每一个新event的fi应该恰好等于上一个event的i+1，否则可能出现了丢包，请从step3重新进行初始化。
7.每一个event中的挂单量代表这个价格目前的挂单量绝对值，而不是相对变化。
8.如果某个价格对应的挂单量为0，表示该价位的挂单已经撤单或者被吃，应该移除这个价位。
注意: 因为深度快照对价格档位数量有限制，初始快照之外的价格档位并且没有数量变化的价格档位不会出现在增量深度的更新信息内。因此，即使应用来自增量深度的所有更新，这些价格档位也不会在本地 order book 中可见， 所以本地的 order book 与真实的 order book 可能会有一些差异。 不过对于大多数用例，500 的深度限制足以有效地了解市场和交易。
