Indicadors with alert

New comment
 
Greetings to all,

I to discover this sufficiently beneficial pointer and it would like to know of somebody is possible to introduce an alert one to go off all time that a new signal to appear. I am very thankful who to give this aid to me.

Sincerely,

Eduardo Robson

...
if( i == hhb ) {
    b1[i]=High[hhb]+SignalGap*Point;
    PlaySound( "alert.wav" );
}
if( i == llb ) {
    b2[i]=Low[llb]-SignalGap*Point;
    PlaySound( "alert.wav" );
}
...
When the arrow is drawn, an alert is sounded. However the problem is that when the arrow is drawn, the signal is already late by at least dist/2 bars. So I think this is not a good indicator.

PS. Look also zig-zag indicator.
 
I perceived this. Now using this pointer in the timeframe M30 and H1 the signals are more necessary. More I am been thankful for the gentility.

If somebody will have some indication will be well very well coming.

Good Businesses
Eduardo
 
Hello! I need help in understanding the code. Could someone explane to me what signalGap is and what it is used for?
