Hello everyone, as in other threads read i have the problem with the alerts of expert advisor with the notifications that are repeated continuously and sending many e-mails. The code i use is this,,,, intraday time frame 15 minutes:
BUY:
Buy:=Fml("My HMA Centrata 128-16-32")>Ref(Fml("My HMA Centrata 128-16-32"),-1);
Sell:=Fml("My HMA Centrata 128-16-32")<Ref(Fml("My HMA Centrata 128-16-32"),-1);
buy AND BarsSince(Ref(buy,-1))>BarsSince(Ref(sell,-1));
SELL:
Sell:=Fml("My HMA Centrata 128-16-32")<Ref(Fml("My HMA Centrata 128-16-32"),-1);
Buy:=Fml("My HMA Centrata 128-16-32")>Ref(Fml("My HMA Centrata 128-16-32"),-1);
sell AND BarsSince(Ref(buy,-1))<BarsSince(Ref(sell,-1))
I have a latch becouse otherwise the signals of buy and sell are repeated and i have read in other threads that i can use a latch in way to trigger once on each buy - sell notifications
I do not know very well the different latch that can be used in different cases, and i do not know how to use them
help

It is hard to say definitively whether this would work with your formulas or not, but aside from disabling the Recalculate Expert Live feature (which makes it so that the formulas only calculate at the end of the price bar), you could try using the Cross function instead of using greater than / less than, such as:
Buy:=Cross(Fml("My HMA Centrata 128-16-32"),Ref(Fml("My HMA Centrata 128-16-32"),-1));
Sell:=Cross(Ref(Fml("My HMA Centrata 128-16-32"),-1),Fml("My HMA Centrata 128-16-32"));
buy AND BarsSince(Ref(buy,-1))>BarsSince(Ref(sell,-1));

Thanks for the quick reply.
I know the possibility of disabling the function of recalculate expert live but i wanted to avoid using even because is general for all expert. I try the modified code that you wrote and then tell you if it's okay.
Thanks

I tried changing the code as written you but the result is very similar to the code that I used. I have disabled the function of recalculate expert live but is a little tedious to enable and disable this function for some expert and others do not. The function of recalculate expert live should be included in the expert editor and not in general options, I hope to be done in future versions of metastock.
Thank you

One thing to keep in mind, if the value crosses up and you get an alert, it can still cross back down, then cross back up again triggering a new alert. Depending on how easily the values cross each other, it may not help that much.
The feedback is appreciated!

You may want to look at the Forum DLL in the Files section (click Files tab above). There is a Latch function therein that may do specifically what you need. I am not an expert on this DLL, but there are others here on the forum that have experience using this.
