Answer : I'm an EOD trader. So I am not using R/T data. 'My example' code works fine and does not give me repeating SAY's. But with you're code I do have a problem. It's called 'syntax error' because of an expecting "(" : Buy=Ref(Cross(C,MA),-1);
So assuming you want something like "Buy=Cross(C,MA(C,10));" I have no problems with the SAY() clause. 'My example' code :
LongMA = EMA( C, Param("Long Period", 50, 30, 200, 5 ));
ShortMA = EMA( C, Param("Short Period", 5, 3, 50, 1 ));
Buy = Cross( ShortMA, LongMA );
Sell = Cross( LongMA, ShortMA );
Buy = ExRem(Buy,Sell);
Sell = ExRem(Sell,Buy);
// Now use "Bar Replay" to walk thru the time series ...
if (LastValue(Buy)) Say("Buy");
if (LastValue(Sell)) Say("Sell");

Question: Let's say you are trading 5 minute intervals, but you're getting R/T data every second. Your condition was True on the last bar (or the current one). Aren't you going to get Say() repeating itself every second for five minutes?
Buy = Ref(Cross(C,MA),-1);
if (LastValue(Buy)) Say("Buy");

Just the famous example with Cross() to let Say() work. Interesting to know that I am not the only one having problems with AlertIf(). Thanks and happy holidays for you too, Ton.

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(< /FONT>"Buy");
if (EndValue(Sell)==1) Say("Sell");
Ton.

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?
