How to remove extra arrows in an indicator?

New comment
 

Hi everyone,

I wrote an indicator to display arrows & alert me whenever the closed candlestick is above 50, 100 and 150 EMA lines.

That worked and I'm happy with the code. But there's an issue occurred:

When I run the indicator, it draw many extra arrows as soon as the conditions are met. So, how may I disable creating more arrows when the first one is draw?

remember (static) the first arrow direction, until new arrow != new direction.

Most likely there is an error in your code, resulting in multiple arrows instead of only one.

Thanks Mohammad, but can't understand what you mean

Actually no, the code doesn't generate any error. I can't understand how should I modify it

Don't Alert on a signal. Act on a change of signal.

What I do in mine is create a variable" int lastWas=5;  "  Then I check to make sure "lastWas" is not equal to 1 for up arrow or 2 for down arrow. So something like  ...  

 if

( iClose(NULL,0,1)>iMA( bla bla bla)

&& iClose(NULL,0,2)< iMA( yadda , yadda, yadda) 

&& lastWas!=1 //1 is up, 2 is down

)

{

Buffer1[1]=iLow(NULL,0,1);

lastWas=1;

}

As long as lastWas is not equal to 1 , it will paint, else..nothing but clean chart :)
