不用滴滴咿改寫吸嘉嘉感覺好帥(ADK)
上次把模擬資料用DDE打到EXCEL上再用AmiBroker的Plug-In去收雖然用C#寫蠻簡單的(ptid=145893 #8樓)
但是有個EXCEL有時還是感覺很礙眼,還有DDE的欄位設定囉唆又難看
之前也看ADK說VC6和DevC可以用,只是不知怎麼開始
寫程式總是看別人寫出來後覺得簡單,自己要從頭開始寫都覺得很難
終於孤狗到一個可用的ADK資料,看起來就是和以前舊公司所收藏的到的API有關
總是要有個起頭,想說街口轉1000索討試試看無妨,就收到了網頁所描述神奇的C++專案程式源碼了
先把bin的dll丟進AmiBroker的Plugins的資料夾內,有vc,devc,bcb好幾個版本,先試其中一個32位元的
果然順利在AmiBroker上可以查看到
加入新的database觀察看看,確實可以選擇這個資料源
不過這個資料源要載入另一個dll不存在,所以出現訊息提示
就把之前接收模擬資訊源用的dll丟進去AB的安裝資料夾內
重開AB,還是有錯誤,原來是我的dll太舊了
不過上面的種種現象說明這個ADK開發的plugin是可以運作的,所以就來研究程式碼吧!{:4_661:}
因為這份ADK的IDE有很多版,想說就在這台AB的測試虛機中下載了小小的DevC
這個不用安裝,硬碟只吃60MB,把專案一開,居然是這樣寫
最重要的是按了編譯就真的出來新的dll了,這也表示值得花時間看下去
這個看下去我看了很久,看了好多天就不用說出來笑了{:4_679:}
重點是我改成功了,看影片
雖然手上收行情的api比較舊還是可以用的啦! 程式裏不要調用新功能就可以了
看別人的程式真的好簡單,註解比程式碼還多全部一起算
ADK的部分不到400行,收行情的部分也300多行而已
如果之前在舊公司有備份到feed server就好了,不管券商行情多難用都可以變簡單
之後我也想試試x64是否也行,又下了DevC5也是可攜版(不用安裝)不過很大要360MB
果然也是順利編譯x86和x64的版本,後來拿去另一邊有VC10的試,也是都不用改
選Win32就邊出x32的版,選x64就編譯出x64的版,把自己編譯的都拿去試過AB全部OK
裡面還有BCB5和BCB6的版,裡面附有一個小工具,只要BCB編譯後用小工具處理過AB就也可以使用
不過我沒有BCB可以試,就不知道是怎樣的情況了
結論是 還蠻好玩的 比接DDE直接方便比寫C#帥{:4_186:}
ADK的程式碼像這樣,提到舊版的地方就是我修改過的{:4_624:}//////////////////////////////////////////////////////////////////////////////////////////////////////////

#define PLUGIN_VERSION 10000
#define PLUGIN_ID PIDCODE( 'F', 'T', 'W', 'D' ) //在AmiBroker的全部Plug-in中需為unique,若需多個相同方式的dll改這裏不一樣即可
#define THIS_PLUGIN_TYPE PLUGIN_TYPE_DATA //設成為資料源模式( Chart-Data or real-time , Tick資料也是比照Chart-Data要生給AB抓而不是AB自己會累積產生)
/* // PLUGIN_TYPE Note!!
詳見 ADK/adk.html 1.2 INTERFACE ARCHITECTURE
基本上 AmiBroker 判斷PLUGIN是否有提供以下介面函式
GetQuotesEx - 歷史數據(chart-data) ... 會來撈一個array的歷史資料(如KD) (Tick也是要這樣處理)
GetRecentInfo - 即時數據(real-time) ... 會來撈報價如 trade, bid/ask, days high/low, etc...
#define PLUGIN_TYPE_AFL 1 //PLUGIN_TYPE_AFL 功能模式吧... 好像只是提供一些功能方便於AmiBroker取值
For AFL plugins this second initialization phase happens when AFL engine starts
for a very first time initializing its function table. Then AmiBroker performs the following operations:
AmiBroker calls SetSiteInterface() function exported by the plug in. The site interface is used later in DLL for calling back various AmiBroker functions (including allocating/freeing memory, reading/writing AFL variables, calling back AFL functions)
AmiBroker calls Init() function from the plug in DLL that should be used for initializing working variables/allocating extra memory if necessary
AmiBroker calls GetFunctionTable() from the plug in DLL. In this step the AFL functions provided by the DLL are added to the internal AmiBroker dispatch tables allowing futher calls of these functions.
Note that this is done only once after loading DLLs in the newer versions of AmiBroker (4.10 and up).
#define PLUGIN_TYPE_DATA 2 //PLUGIN_TYPE_DATA 資料源模式, 於AmiBroker中會出現在 Data Source 中可以選擇
1.需提供 SetTimeBase 回應 AmiBroker 可接受什麼時間間隔等級的資料
2.可透過 GetStatus 讓 AmiBroker 知道資料源的連線狀況 且會於介面右下角顯示對應的狀態與訊息
3.當於AmiBroker的選單進入 File->Database Settings 選擇此資料源確認後, 就會呼叫 GetQuotesEx
(a)如果是舊版的AmiBroker則是呼叫 GetQuotes 如不想支援舊版可以不用設計 GetQuotes
(b)若要支援舊版的AmiBroker可以透過 Plugin_Legacy.h 的定義和新格式做轉換
(c)於AmiBroker的選單進入 Symbol->New 新建一個商品代碼時確定後也會呼叫 GetQuotesEx
(d)可透過 ::SendMessage( g_hAmiBrokerWnd, WM_USER_STREAMING_UPDATE, 0, 0 ); 的方式通知AmiBroker呼叫 GetQuotesEx 更新資料
For Data plugins the second initialization phase happens when given data source is selected
for the very first time in current AmiBroker session.
Then AmiBroker just calls Init() function from the plugin that should be used for initializing working variables/allocating extra memory if necessary.
No other function is called for data plugins at this time.
#define PLUGIN_TYPE_AFL_AND_DATA 3
看就明白這是 AFL + DATA 混合的模式
#define PLUGIN_TYPE_OPTIMIZER 4

/* // real-time 注意這幾個
GetPluginStatus() function is optional and used mostly by real-time plugins to provide visual feedback on current plugin status. It provides a way to display status information in the AmiBroker's status bar. For example implementation of GetPluginStatus() function please check QuoteTracker plugin source.
The following two functions are implemented only by real-time plugins:
PLUGINAPI struct RecentInfo * GetRecentInfo( LPCTSTR pszTicker ); // RT plugins only
PLUGINAPI int GetSymbolLimit( void ); // RT plugins only
GetRecentInfo() function is exported only by real-time plugins and provides the information about the most recent trade, bid/ask, days high/low, etc (updated by streaming data).
It is called by AmiBroker's real-time quote window on each window refresh (occurs several times a second). The function takes ticker symbol and returns the pointer to RecentInfo structure described above.
GetSymbolLimit() function is exported only by real-time plugins.
It returns the maximum number of streaming symbols that plugin and/or external data source can handle.
The result of this function is used to limit the number of symbols that are displayed in real-time quote window

最核心的 getquoteex 的程式沒 show 出來
WOW
kuolung大來出考題了{:4_620:}
不過這比較像是考我的抄襲能力耶
其實像上次用EXCEL作皮看報價,現在換用AB作皮而已
如果會收行情,收行情那塊就能把需要的資料都弄齊也能寫檔不會有什麼問題
也就是收行情本身也是能獨立運作的,AB是平行作業再收一份行情
這樣收行情與存檔的部分才不會因為AB要開開關關而受影響
看kuolung大也是另寫server,AB則透過server收行情與回補這也是相同的概念吧!
模擬資訊源那種行情源原本就有TickWriter可紀錄Tick,
要組成各種cycle的KD或轉成歷史也都沒什麼問題
所以如果存檔就在AB跑的PC上,那GetQuotesEx就是讀檔回補就可以了
很多情況下我只有想要報價而已,歷史對我來說沒什麼意義
在這裡就表現一下程式大概怎麼寫的想法,不然太過累贅就又不好讀了
以網路這份資料 webrtqt.fortunengine.com.tw/rtdata/k-chart/day-2330.txt 存檔作示範
用之前nes大那個CsvReader的dll,抄這份程式碼的作法
弄成很獨立完整加入就可以用的程式碼,像這樣(原本ADK的註解也保留)

// When AmiBroker calls GetQuotes function it allocates

於AB上出來就是這樣
由DataWindow對照網頁內容
IndexDateDateOpenHighLowCloseVolume

右邊紅色的的量是最後一根(2019-01-28)
IndexDateDateOpenHighLowCloseVolume
5102019/1/28229.5229.522822925986
其實這裡並不難,如果收行情那裡就直接用ADK的struct Quotation格式保存了資料
那GetQuotesEx可能就也只是以assign為主,頂多考慮各種KD是否要在這裡組出來
就像行情那裡也是,因為收行情那裡直接用ADK的struct RecentInfo保存資料,
所以GetRecentInf簡單成這樣 PLUGINAPI struct RecentInfo * GetRecentInfo( LPCTSTR pszTicker )
{
if (hmDbfTCdll)
{
RecentItemRefer *spRecentRefer = GetRecentItemRefer(pszTicker);
if (spRecentRefer)
return &(spRecentRefer->spRecentItem->sRecentInfo);
}
return NULL;
}
考慮線圖Tick進來則大概是這樣的作法,在行情這邊通知AB來重撈資料
PLUGINAPI struct RecentInfo * GetRecentInfo( LPCTSTR pszTicker )
{
if (bTickNotify)
{
bTickNotify = false;
PostMessage( g_hAmiBrokerWnd, WM_USER_STREAMING_UPDATE, 0, 0 );
}
if (hmDbfTCdll)
{
RecentItemRefer *spRecentRefer = GetRecentItemRefer(pszTicker);
if (spRecentRefer)
return &(spRecentRefer->spRecentItem->sRecentInfo);
}
return NULL;
}
