Hi everyone, I'm Max. I am a neophyte in the MQL4 programming and speak little English, so excuse me. I have a problem I can not solve.

I have an indicator / alert built on CCI Histogram. I inserted the conditions that work. I would like that the last bar of the histogram, was read at the opening

of candelstick and not the closure of candelstick.

I hope someone can help me.


Thank you all, greetings, Massimo.

 

 

 for(int i = limit-1; i >= 0; i--)

     {
      if (i >= MathMin(5000-1, rates_total-1-50)) continue;  
      //Indicator Buffer 1
      if(iCustom(NULL, PERIOD_CURRENT, "CCI Histogram", 4, 0, false, 0, false, 1, "TrendCCI", false,  0, i) < iCustom(NULL, PERIOD_CURRENT, "CCI Histogram", 4, 0, true, 0, false, 1, "TrendCCI", false,  0, 1+i) //CCI Histogram < CCI Histogram
      && iCustom(NULL, PERIOD_CURRENT, "CCI Histogram", 4, 0, true, 0, false, 1, "TrendCCI", false,  0, 1+i) < iCustom(NULL, PERIOD_CURRENT, "CCI Histogram", 4, 0, true, 0, false, 1, "TrendCCI", false,  0, 2+i) //CCI Histogram < CCI Histogram
      && iCustom(NULL, PERIOD_CURRENT, "CCI Histogram", 4, 0, true, 0, false, 1, "TrendCCI", false,  0, i) > 0 //CCI Histogram > fixed value
      && iCustom(NULL, PERIOD_CURRENT, "CCI Histogram", 4, 0, true, 0, false, 1, "TrendCCI", false,  0, 2+i) > 0 //CCI Histogram > fixed value
      && iCustom(NULL, PERIOD_CURRENT, "CCI Histogram", 4, 0, true, 0, false, 1, "TrendCCI", false,  0, 2+i) > 0 //CCI Histogram > fixed value
      )
        {
         Buffer1[i] = Low[i];

Hi, I post all the code. I would like, if possible, that the alert is shown when opening the spark plug if the conditions are complied with the code.

There must be 3 bars of decreasing CCI, but the alert should appear only once at the opening of the current candle.

I hope I was clear. Sorry for my poor English, greetings, thank you, Max.

You have a function for an alert, but the function is not called

Hello Gumrai. I updated the file that works in part. The alert appears at the opening of the candle but in the course of its

formation may disappear. I would rather that once appeared, if the conditions are valid at the opening of the candle, do not disappear anymore.

Greetings, Massimo.

PS:

Hello to all. I would like to schedule an alert just open the candle, that is, if the opening of the candle are all the conditions for the arrow that appears you have to stay until the end of the candle, even though during its formation conditions change.
I am very inexperienced and I hope someone can help me.
Sorry and thanks to all, Massimo.

omissamf: in the course of its formation may disappear. I would rather that once appeared, if the conditions are valid at the opening of the candle, do not disappear anymore.
Valid only at the opening
if(Volume[0] < 5) Buffer2[i] = 0;
if(Volume[0] < 5) Buffer1[i] = 0;
Valid anytime during the candle
// Buffer2[i] = 0;
// Buffer1[i] = 0;
 Valid at the end of the candle
Buffer2[i] = 0;
Buffer1[i] = 0;

WHRoeder Hello, thanks for the reply. I modified the code as you suggested, but the problem remains. In fact, after the opening of the candel if the conditions vary the arrow disappears. I would like instead remain visible regardless of what happens after the opening of the candle.

thank you so much, Massimo.

Hi, I could use the Sleep () function, to stop the indicator running for 58 seconds? I said nonsense?
How could I integrate it into the code?
Regards, Massimo.
if( Volume[0]>5) Sleep(50000);

You cannot use Sleep in an indicator.

Ok GumRai,

I was trying and I've seen that does not work. How can I do? He's trying to study, but I can not find the solution.
thanks Massimo.
