AmiBroker Development Kit (ADK) 的設計, 大致上就是寫一個dll專案, 主cpp裏include ADK提供的 Plugin.h 然後需要提供以下functions: PLUGINAPI int GetPluginInfo( struct PluginInfo *pInfo ); PLUGINAPI int Init(void); PLUGINAPI int Release(void); 要設計Realtime Quote則需再提供 PLUGINAPI int GetStatus( struct PluginStatus *status ); 如果還要支援線圖資料則再增加 PLUGINAPI int GetQuotesEx( LPCTSTR pszTicker, int nPeriodicity, int nLastValid, int nSize, struct Quotation *pQuotes, GQEContext *pContext ); 整個ADK其實在GMDS上要運用只需保留一個檔案, 就是 ADK\Include\Plugin.h 就可以了, 但是 Plugin.h 裡面寫了#include "plugin_legacy.h", 所以可以把 plugin_legacy.h 也留著, 不過這只有在跟舊版的AmiBroker( < v5.27)搭配時才有作用, 如真的不需要就把 Plugin.h 裏的include註解掉, 檔案也就可以刪了~ 真的沒什麼用 而要接收DTS資訊源(這裏會用HFOCX的外匯行情作示範) 只需要有 DbfTCdll2.dll 就可以作了, 如果是寫C++則可以引入 DbfTCdll2.h 可以寫的比C#更容易! PS: 與GMDS的api是全面性支援的概念有所不同, ADK 由於是用 _cdecl (VC預設) 方式宣告函式, 官方說明是可以使用VC6和DevC開發, 而BCB雖然也能正確編譯, 但作出的dll AmiBroker是不能用的!這裡的示範, 為了調用方便, 設計兩種索引方式, 大致如下規劃 void *vpQuoteIndexHandle = NULL;//行情庫管理
int iCountContracts = 0;//商品數
typedef struct
{//商品資料結構
struct RecentInfo sRecentInfo;
} RecentInfoDataItem;
typedef struct
{//商品索引用, 由行情源對應商品的記憶區塊
RecentInfoDataItem *spRecentItem;
} CommodityRefer;
typedef struct
{//商品索引用, 由商品短碼反查
RecentInfoDataItem *spRecentItem;
CommodityRefer *spCommodity;
} RecentItemRefer;
CommodityRefer *spCurrCommodity = NULL;
//資料源欄位代碼 #define Tag_UniSymbolName "1" //結合"93" "94" "95",多重資訊來源也是Unique的長代碼 #define Tag_ExchangeName "93" #define Tag_ContractName "94" //通常包含"95"的內容,於單一資訊源是Unique的短代碼 #define Tag_ContractDate "95" #define Tag_OpenInterest "13" #define Tag_Reference "14" #define Tag_Open "6" #define Tag_High "8" #define Tag_Low "10" #define Tag_Close "12" #define Tag_Bid "18" #define Tag_BidVol "19" #define Tag_Offer "20" #define Tag_OfferVol "21" #define Tag_Last "22" #define Tag_LastVol "23" #define Tag_TotalVol "27" //還有很多,有用到再找
程式內容大概這樣寫 CommodityRefer * GetCommodityRefer(const char *cpDBName, const char *cpSymbol, bool bAutoCreate = false)
{//商品索引用, 由行情源對應商品的記憶區塊
spCurrCommodity = (CommodityRefer *)fnDbfTCdll_GetItemQuoteMemory(cpDBName, cpSymbol);
if (!spCurrCommodity && bAutoCreate)
{
CommodityRefer sCommodity;
memset(&sCommodity, 0, sizeof(sCommodity));
spCurrCommodity = (CommodityRefer *)fnDbfTCdll_CreateItemQuoteMemory(cpDBName, cpSymbol, &sCommodity, sizeof(sCommodity));
return spCurrCommodity;
}
return spCurrCommodity;
}
char caContractDBN[] = "RecentItemRefer";
RecentItemRefer * GetRecentItemRefer(const char *cpContractName)
{return (RecentItemRefer *)fnDbfTCdll_GetItemQuoteMemory(caContractDBN, cpContractName);}
bool MakeRecentItemRefer(CommodityRefer *spCommodity) {//商品索引用, 由商品短碼反查 if (spCommodity) { CommodityRefer &sCommodity = *spCommodity; struct RecentInfo &sRecentInfo = sCommodity.spRecentItem->sRecentInfo; RecentItemRefer sRecentRefer = {sCommodity.spRecentItem, &sCommodity}; return (fnDbfTCdll_CreateItemQuoteMemory(caContractDBN, sRecentInfo.Name, &sRecentRefer, sizeof(sRecentRefer)) != NULL); } return false; }
即時數據接收的Callback大概是這樣的內容 void DBFTCDLLAPI TagDataProcessFunction(const char *cpDBName, const char *cpVarName, const char *cpSymbol, const char *cpNewValue, const char *cpOldValue)
{// 1 - By Tag, 每個商品的每個Tag更新都會呼叫
if (!spCurrCommodity) //同商品會有多次通知,僅需檢索一次
spCurrCommodity = GetCommodityRefer(cpDBName, cpSymbol, true);
//這裡的這個CB其實沒要作什麼事,可以取消不用 (留著只是示範)
//或者也可以設計一些flag幫助 ItemProcessFunction 處理
}
void DBFTCDLLAPI ItemProcessFunction(const char *cpDBName, const char *cpVarName, const char *cpSymbol, const char *cpNewValue, const char *cpOldValue)
{// 2 - By Item, 有更新的商品會呼叫 (傳入之cpVarName,cpNewValue,cpOldValue等參數為NULL)

如上之設計, 如果想玩其它花樣, 可以用以下方式隨時取得商品表與內容, RecentInfoDataItem *sp
DataItem = (RecentInfoDataItem *)fnDbfTCdll_STManGetTickMemory(vpQuoteIndexHandle, iIndex, false);
其中iIndex就是直接調出第幾個商品 0 <= iIndex < iCountContracts 所以用一個for-loop就等於將整個商品表掃一次了~ ADK要設計的內容就很簡單了...Init/Release PLUGINAPI int Init(void)

把作出來的dll放AmiBroker安裝路徑下的 Plugins 資料夾中 例如 C:\Program Files\AmiBroker\Plugins\ 而收DTS用的 DbfTCdll2.dll 則放AmiBroker的工作路徑下 例如 C:\Program Files\AmiBroker\ 然後跑AmiBroker起來, 到選單 Tools --> Plug-ins... 可以看到 然後有選單看是要新增 File --> New --> Database... 還是編輯 File --> Database setting... 就可以選這資料源來使用了 沒有任何商品代碼嗎? 從選單的 Sumbol --> New... 將下面整行內容貼進去 AUD/USD,AUD/JPY,USD/CAD,USD/CHF,CHF/JPY,EUR/USD,EUR/CHF,EUR/GBP,EUR/JPY,GBP/USD,GBP/CHF,GBP/JPY,HKGOLD,USD/JPY,LKG,GOLD,GOLDX,SILVER,SILVERX,NZD/USD 按OK鈕之後, 所有輸入的商品代碼就會列在Symbol視窗格, 然後於視窗格中按Ctrl+A全選, 再用滑鼠右鍵點出功能清單, 點選 Add to Realtime Quote windows 這樣就完工了~ 如果還沒有看到Realtime Quote視窗格, 則是要在選單列的 Window 那邊, 把Realtime Quote項目點勾起來即可 本例中與上游(UniDBF)的上游(Pats-Emu)相比對 當然, 如果使用VC10以上或DevC5就能產出x64的dll版本搭配64位元版的AmiBroker囉! 更進一步就是設計設定的介面, 可以用文件編輯ini的方式或是比較搞剛作GUI, 依拙見還是選擇前者既簡單又方便, 就請各自發揮了~ 當然, 任何資訊都可以很容易轉成DTS服務, 只要轉成DTS方式服務後, 就都能像上面一樣輕輕鬆鬆運用在AmiBroker裏了... 即便要加入線圖資訊的功能, 透過GMDS提供的 STM很容易就能完美又簡潔的建構出來~ ( 前面提到 iCountContracts 所形成的商品表, 就也是使用STM的範例 ) 這也就是說可以把各種不好使的資訊來源透過GMDS的提供的方式( Feed-Server/API)全都打進GMDS的架構內, 然後不管什麼資訊源最後統一都是最容易上手的DTS介接模式, 再來DTS以下都是維持不變的, 就算源頭換來換去再也不用擔心要大費周章改一堆了! 如能透過券商端提供 TSHS與客端使用PatsEmu-TSHS, 那麼資料完全自動銜接, 也不用再考慮什麼回補問題了~ 針對 DbfTCdll2.dll 的使用上, 關於程式使用dll的方式, 可進一步參考 使用dll的一些基礎見識其它連結: AmiBroker |
