RE: [amibroker] Example code for using Say()

["Herman" <psytek@xxxxxxxx>]

Hello Ton,

You are correct and you should initialize the text variable. However your
solution doesn't work in a my real time application. Of course, if your
simpler solution works for you should use it.

I am absolutely delighted with the Say() as it lets me focus on and do other
things while trading or running bar-Playback simulations. I don't have to
sit and stare (waste time and get cross-eyed) at the screen to see at what
price my order triggered or what transient error passed, the say() output is
slow and lets you catch it all. For me this is simply utilizing my senses
more effectively. It lets me work under much less intense (normally needed
to catch transient events) conditions. With a little innovation the Say()
can help you create a much more efficient working environment.

Thanks again Tomasz :-)

best regards,
herman

  I have three problems with this code Herman. My first problem is that it
doesn't give me a Buy or Sell sound. So for me it does not work properly.
Secondly, the variable Text will create an error in case there is no Buy or
Sell because it has not been initialized. I would start the code with 'Text
= "";'. And thirdly, why not keeping things simple ( KISS ) ?
  As I told you, the following works fine :

  if (LastValue(Buy)) Say("Buy");
  if (LastValue(Sell)) Say("Sell");

  I am probably not seeing the problems that you're seeing ...

  Ton.

    Sorry, here's a small change to the code - I should have tested it
before posting!

    if(LastValue(Buy))            Text ="  Buy, at,
"+NumToStr(BuyPrice,1.2);

    else if(LastValue(Short))    Text ="Short, at,
"+NumToStr(ShortPrice,1.2);;

    PrevText = StaticVarGetText("PrevText");

    if( StrLeft(Text,5) != StrLeft(PrevText,5) )

       {

       Say( Text );

       StaticVarSetText("PrevText", text);

       }


----------------------------------------------------------------------------


    just FYI I use this type of code in Real-time trading and it seems to
wokr just fine:

    if(LastValue(Buy))            Text = "Buy, at, "+NumToStr(BuyPrice,1.2);

    else if(LastValue(Short))    Text ="Short, at,
"+NumToStr(ShortPrice,1.2);;

    PrevText = StaticVarGetText("PrevText");

    if( Text != PrevText )

       {

       Say( Text );

       StaticVarSetText("PrevText", text);

       }

      Perhaps TJ can add a msg queue or a SayStatus() command so that we can
do the queueing ourself. You may be able to prevent repeats (using Static
variables) and prevent calling Say() to fast, you could insert an
automatically minimum call interval, using GetPerformanceCounter() or
getStatus("RedrawAction"), that is proportional to the number of characters
in your message.

      best regards,
      herman

        I love the new Say(text) command in 4.89 Beta, but often the message
is cut off (apparently by the next pass through the AFL code) before it can
be completely "uttered". Has anyone else seen this problem and figured out
how to "buffer" it?

        Thanks,
        Dale
