Feed-Server行情導入介面與Feed-API

張貼者:2012年8月27日 下午9:25Wei-Xiuang Wang   [ 已更新 2017年9月14日 下午6:35 ]

PatsRaw 與 PatsEmu 程式皆可含有Feed Server服務介面, 透過Feed-API輕鬆完成行情導入系統之工作,
可以獨立運行規劃其他市場行情或介接其他資訊源, 也可用來擴展特定商品(例如指數)或衍伸商品(例如指標),
整合進GMDS架構後, 透過GMDS強大之通訊與架構功能快速相容於原本發展在以GMDS為中台架構的各種應用系統中,
立即享用GMDS簡單便利的介接與開發功能, 同時系統提供可擴展自訂欄位的強悍功能, 應用上之變化與自由超乎想像!

PatsEmu-OBG

這邊以PatsEmu-OBG作介紹, 因為PatsEmu-OBG本身亦是GMDS的一種行情導入規格介面,

PatsEmu-OBG使用 /Source 參數 指定來源 TSHS-TfsRaw, 經由 TcpRDS 收取OBG格式的任意TCP Socket Server來源,
Socket Server透過OBG的通訊格式(五檔/十檔)提供資料, 便可將所需行情導入GMDS架構中

OBG Socket Server <-- TcpRDS <-- TSHS-TfsRaw <-- PatsEmu-OBG

由於PatsEmu-OBG指定 /Source 也是行情導入的功能, 因此搭配具有Feed-Server功能時,
若同時設立 /Source 和 /FeedPort 則是混合模式, 也可僅設立其中一種, 若不設 /Source 則是最基本的 Feed-Server 服務程式,
其它具有Feed-Server功能的PatsEmu與PatsRaw則於啟用 /FeedPort 時, 一律為混合模式運行

Feed-Server

所有PatsEmu(含PatsRaw)可使用 /FeedPort 參數功能 指定服務埠號 啟動 Feed-Server 服務

具有Feed-Server功能的PatsEmu/PatsRaw會含有修改行情之介面功能

Feed 命令
透過Feed命令, 可以針對已存在之商品進行欄位資料修改, 其輸入內容格式完全同Feed-API

SaveFieldList 命令
透過SaveFieldList此命令, 可將現行系統的欄位設定定義輸出到指定的檔案, 檔案為.csv檔格式

欄位定義檔格式
a. 欄位內容不可同時含有半形之單引號( ' )與雙引號 ( " )
b. 欄位內容如果有逗號或單引號,則首尾須以雙引號包起來
c. 欄位內容如果有逗號或雙引號,則首尾須以單引號包起來
d. 每行定一個Tag Field, 各欄欄內容以逗號( , )作分隔, 共須5欄依序為

1. Tag代碼, 例如 123 或 "123" 或 '123' 之設定方式皆可

2. 欄位長度, 依欄位格式設定長度

I: 1~8, 如為1代表數值範圍 -128~127
U: 1~8, 如為1代表數值範圍 0~255
S: 須設0, 實際欄位保留長度則是於欄位格式中填足對應長度

3. 欄位格式

I: 有號整數
U: 無號整數
S: 字串

4. 欄位說明1 (會秀在PatsEmu/PatsEmu的商品資料檢視表中)

5. 欄位說明2 (保留,但須存在)

可修改欄位定義檔擴增所需欄位, 透過 /FieldList 參數 可讓PatsEmu/PatsRaw改以指定的檔案作為欄位定義來源
原已定義之欄位與順序儘可能不作變動, 例如#1 固定是全域性的商品代碼作為唯一的識別Key用不應該被調整,
而10檔買賣#100~#119,#200~#219則是順序上已應用中的程式會透過欄位ID計算檔位所以也不應該被調整

Feed-API

與API PktEvCdll.dll 完全相同, 透過指定Feed-Server之Host後便可進行Data Feed了!
使用API函數
//fnPktEvCdll_SendPacket(char cType, const char *cpMessage, int len, bool bRealPush)
//    cType : 僅允許 0x20 ~ 0x7F , 配合Server端定義之配對設計
//    bRealPush : 是否即時發送, true 立即發送, false 儘可能即時發送
例:
char caData[] = "AAA,92=ABC,93=CME,6=156.50,8=158.00,10=155.80";
fnPktEvCdll_SendPacket('F', caData, strlen(caData) + 1, false);

例中參數說明:
bRealPush : 都設 false 即可
cType : 必須設 'F'
caData : AAA為#1商品代碼,後面為針對此商品,各Tag所想更新的內容, 所設商品若不存在系統自動新增
len : caData長度, 須含ZE

特別欄位說明


#97, #60
十進制數字日期 YYYYMMDD (前端連續0之位數會省略)

#98
十進制數字時間, hhmmss (前端連續0之位數會省略)

#61
十進制數字時間, hhmmssnnn (前端連續0之位數會省略)

#16, #17
日期時間, Unix time(or POSIX time, UTC), 數值內容為自1970-01-01 00:00:00開始所對應的日期時間之總秒數

#96
Bias時區設定, 當Feed API提供 #93 #94 的資料時, 系統會透過Bias設定檔規則, 自動提供該商品所需之 #96 數據內容
因此 #96 應避免透過Feed API來提供數據, 而是於系統上透過Bias設定檔來提供規則 (參考 時區表 , Bias設定檔說明 )
此欄位的提供能透過合適的偏差值設定, 當行情運作時能讓商品有對應交易日(#97)可以參考

#97, #98, #16
此三欄位於任何資料更新時, 系統會同時連帶更新
#97, #98 為依據更新當時之系統時間與 #96 之Bias設定換算所得之結果, 因此 #96必須在所有數據需求之前先提供

#27 TotalVol
當發送此欄位異動時, 系統會連帶更新 #23, #97, #98, #16, #17
如果想另外提供 #23 資訊作取代時, 若發送訊息時將 #23 置於 #27 之前將被系統之計算結果給覆蓋, 可將 #23 置於 #27 之後則能正確取代為所提供之數據

應用實例

市面上投顧最常用的行情系統(證期權股匯市全市場即時行情) 透過Feed-API很容易就可完成轉換...參考Feed-API(AGVS)
