RE: [amibroker] Re: using say("text") (AmiBroker 4.89.0 BETA released )

["Herman" <psytek@xxxxxxxx>]

In Real-Time I rarely use Cross() and I may want to Say() things that are
unrelated to signals, are unrelated to the last bar, and that could become
repetitive. Like error msgs, warnings, alerts before I enter a automated
trade, even synthesized voice debug output. My eyes can only look at one
screen at the time but sound can be picked up from anywhere, allows you to
multi-task much more efficiently :-)

So Static variables solve the problem for me. S0, I am very happy with the
new Say(), I never got the Alert() working for this.

happy holidays,
herman

  I would rather suggest using LastValue, instead of EndValue because
EndValue depends on Range markers
  that may or may not point to the last bar.

    Why Herman ? Say() works fine for me. Next a simple MA crossing system.
Use 'Bar Replay' to walk thru the time array and you'l' get your 'Buys' and
'Sell' ...

    LongMA    = EMA( C, Param("Long Period", 50, 30, 100, 5 ));
    ShortMA   = EMA( C, Param("Short Period", 5, 3, 50, 1 ));
    Buy       = Cross( ShortMA, LongMA );
    Sell      = Cross( LongMA, ShortMA );
    if (EndValue(Buy)==1) Say("Buy");
    if (EndValue(Sell)==1) Say("Sell");

      You need to store any text to ouput in a staticvar and clear this
variable after you output it, below is just one way of doing this. This will
only Say() text when is has changed. You may have to change this when you
need repetative messages, like pyramided trades that say Buy, Buy, Buy, ...


      Text = ParamStr("Enter text to synthesize","Test");
      PrevText = StaticVarGetText("PrevText");
      if
      ( Text != PrevText )
      {
      Say( Text );
      StaticVarSetText
      ("PrevText", text);
      }

      best regards,
      herman

        Thanks, I may be misunderstanding Flip but my guess is it should be
the opposite,
        something like ExRem() to only sound message once on the first
occurrence.
        but I am not even sure what to include in that statement as arrays.

            if condition say("my message");

        I would like to be said only once (the first time condition is true)
and only on the last bar
        (which I will take care of after I figure out how to restrict this
event).

        I haven't done this yet, but Flip function should work.

            How does one use the say("text") function such that it is only
            stated once and does not repeat even if the condition that
            it depends on continues to be true?
