Re: [amibroker] OLE automation: How to set Param/ParamStr/ParamDate value?

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

Sending keystrokes would not be any faster than file based data transfer but surely less reliable.

If you are after BT/Explore just modify the FORMULA itself (set up some markers so you can easily parse the file,
this technique is used by IO, as far as I know). It is easy because AmIBroker automatically re-reads formula
if you call Backtest/Explore via automation.

  Thanks for all these ideas! (I haven't tried to flap my arms yet :-)
  The AutoIT/ActiveX way takes more time since I am not familiar with VB.
  A DLL plugin or ODBC is overkill for my purpose.
  So I just used a plain file to transfer the parameters. To speed things up, I use static variables in the formula to control file access and cache values, so that it only needs to read the file once at the beginning of BT/Explore.

      Or... you can write a DLL plugin.
      Or... write an Active X
      Or... store your "dynamic" values in database and access them via ODBC plugin

        The way you describe is not that bad actually. 

        A more efficient way would be to use "AutoIT"  www.autoit.com  to click the buttons for you and enter the text.  It has an activeX component as well as a dll that you could use within your script or you could call an exe that it can build.

          Thanks dingo:

          I am wondering what's the best way to pass parameters to a formula dynamically from JScript.
          A way to do it is through a file: the script writes some dynamic values to a file and the AFL formula will reads and parses the file.
          However, this would be slow and cumbersome. 
          Any suggestion will be appreciated,

          - Mark

              I am writing an automation script but couldn't find a way to set values for Param/ParamStr/ParamDate etc. I can only use their default values.
              Is there a way to set their values in JScript?
              Thanks,

              - Mark
