Thanks for the sniplet Ed. After adding just one closing brace to the
first four lines its working for me.. but have a couple of questions and
some validations just so i understand how its working.
* Chart redraws every so many seconds (10secs default) and evaluates
all the rules in the afl. Or does it happen more often; because i see my
incoming ticks changing the bars more often? so evertime a new tick come
in is the chart and indicators redrawn?
I am still testing but i have added the following lines at the end of
your code to cover for situations where a signal intermittently comes
and goes away within a 5min bar; to get the recurrent says i am
resetting it every chart refresh..
else if( (!LastValue(Buy) AND !LastValue(Cover) AND !LastValue(Short)
AND !LastValue(Sell)))
{
StaticVarSet( "buyVar",0);
StaticVarSet( "sellVar",0);
StaticVarSet( "shortVar",0);
StaticVarSet( "coverVar",0);
//Say("reset done");
}
How it is working?
* First time around none of the myBuyVar, mySellVar etc are
initialized; so StaticVarGet returns zero. And say for the first time my
buy rules are triggered, it goes into the if statement block and sets
buyVar to 1 and essentially resets all others to zero (useful from the
second execution onwards).
* Now that buyVar is set to 1, next chart refresh gives myBuyVar a
value of 1 and this prevents from Say( "Buy" ) executing again and
again; until it is reset by some other if statement block.
* If my system covers and goes long at the same time, then i better
get both signals and i should remove the three extra ANDs in this
statement..
(LastValue(Buy) AND !LastValue(Cover) AND !LastValue(Short) AND
!LastValue(Sell))
PS: AB support actually suggested using LastValue(Buy) within AlertIf
statement just directly; i would think if the chart refreshes every
10secs or so and i use LastValue(buy) within the alertif statement it
should work if it is reading the signal from the last bar but somehow it
is not; do you think you know why that one doesnt work?
thanks a bunch again!

(ofcourse rules are simplified); and the way i am using them now is i
plot the graphs and that shows the buy/sell arrows; all i wish is when
it is creating these arrows, it also shouts out loud so that i dont have
to sit at the screen but do something more useful like.. reading a book
or yoga :) and dont care until i hear out a loud sound about my entry..
the problem i run into is it only works intermittently (when the cursor
is on the bar before which the signal is coming); somtimes the alerts
sound; sometimes they dont..
