反覆來回幾次與 AB 技術支援的電郵詢問後,確定了這一點: 指標或畫圖的資料無法處理來自兩個不同的資料庫!
這是 AB 很大的敗筆,會造成資料處理上的受限。 我也回信希望爾後他們下一版本可以改善這個問題。
底下是 AB 的回信:
There is no direct plugin for TradeStation - so you would need to have
quotes exposed through DDE if you want to use DDE plugin (provided that TS
supports that).
In general - if you want to use 2 separate DDE-based sources (with
different links), then you would need to set-up 2 databases.
Note that if you just want to chart data of 2 different symbols, then one
database should be fine, as AmiBroker DDE configuration allows you to enter
link templates instead of hard-coded entries (so you can use e.g. {ticker}
template, which is then replaced by the actual symbol you call) - read:
http://www.amibroker.com/dde.html
You can't read 2 databases from one instance of AmiBroker - i.e. you can process the databases separately in 2 instances of the program (2 copies of AB running at the same time), but each instance will be independent from the other one. |
