indicator not working without recompile

I have an indicator that I have written and it is my first indicator.
It highlights candles that are twice the average size of the last so many candles. it highights the candles with a message.

In a separate window you can see the candle size against the average size plotted.

It is the message I am having problems with. If I return to my screen and re-compile the code all the messages pop onto the chart as normal, where they remain. But an hour or so later when I want to see more of the candles identified I have to recompile again, and then they appear.

What have I done wrong?

code -
#property indicator_separate_window
#property indicator_buffers 2
#property indicator_color1 Black
#property indicator_color2 Red
int limit;
static datetime BARSTART;
int N,s;
double AVG1[];
double candle[];
double huger=1.5;

Comment(" time ",Time[0]," barStart ",BARSTART," avg ",AVG1[N]," candle ",candle[N]," ",High[N]-Low[N]);
}

// check for extra large candles
if (candle[N]>AVG1[N] && Open[N]<Close[N])
{
ObjectCreate(PatternText[N], OBJ_TEXT, 0, Time[N], Low[N] - (50*Point));
ObjectSetText(PatternText[N], "Huge candle", 9, "Times New Roman", Blue);

}

You are not using ObjectCreate() correctly. The names you are using are not unique. The value of N refers to different bars as new bars are created.
Try using the time of the bar as the name of the text object: TimeToStr(Time[N]);

Or you could move and reuse the objects with ObjectMove()/ObjectSetText().

Embed code in your posts with the tags: [ CODE]my code[ /CODE] or [ PHP]my code[ /PHP] for best rendition.

Many thanks XAPHOD. I will do some more investigating on these subjects.

So you would do this for example.
ObjectsDeleteAll() is being used incorrectly too. It takes the window as the first parameter.
One would clear the object of the above code like this:
