Yes this will give you only one signal BUT... only if at one time (one scan) only ONE type of alert is generated per symbol.
The problem is that in your formula cover = buy so when buy alert appearsyou receive also cover alert.
So you should use:
AlertIf( Buy, "", "Buy / Cover Stock", 1 , 1 + 2 + 4 + 8);
AlertIf( Sell, "", "Sell / Short Stock", 2, 1 + 2 + 4 + 8 );
to avoid repeated signals.

Subject: Alert / Scan every XX minutes
Tomasz,
Re: RT Alerts and Scan
Situation:
I have an indicator that triggers my Buy/Sell/Short/Cover signals.
Buy = Cross(rs, BuyLine);
Sell = Cross( SellLine, rs);
Short = Sell;
Cover = Buy;
I am using 15 minute bars. Delay = 0, Buy on Open, Sell on Open.
I set SCAN every 1 minutes.
Set #1:
AlertIf( Buy, "", "Buy Stock", 1 , 1 + 2 + 4 + 8);
AlertIf( Sell, "", "Sell Stock", 2, 1 + 2 + 4 + 8 );
AlertIf( Short, "", "Short Stock", 3, 1 + 2 + 4 + 8 );
AlertIf( Cover, "", "Cover Stock", 4, 1 + 2 + 4 + 8 );
Set #2:
AlertIf( Cross(rs, BuyLine), "", "RS Buy", 10, 1 + 2 + 4 + 8 );
AlertIf( Cross( SellLine, rs), "", "RS Sell", 10, 1 + 2 + 4 + 8 );
AlertIf( Cross( SellLine, rs), "", "RS Short", 10, 1 + 2 + 4 + 8 );
AlertIf( Cross(rs, BuyLine), "", "RS Cover", 10, 1 + 2 + 4 + 8 );
Questions:
1.. Re: Set #1 should only give an alert on the Open of a 15 minute bar, per my Settings, correct?
2.. Re: Set #2 this should give an alert based on tick data. Wheneverthere is a cross, there should be an alert regardless of bar status. Correct?
3.. Despite using 1 + 2 + 4 + 8 or blank (default) in the fifth parameter, I am still getting repeated alerts for same time and signal. Why?
As you can see in the screen shot below, IDPH is giving repeated alerts.
Thanks,
Rick
