Cross Abv/Blw - Double arrow question

January 6th, 2011, 11:57 AM

Hello,
I'm new to C#-Ninja programming and cannot figure out the problem. Is there a way to display only one arrow per cross please? Please see attached screen shot. Is there error in the code(attached)?
I'd appreciate if anyone would be willing to help. This should be simple problem for any experienced programmer. And I hope it is not too much to ask to share your knowledge resolving this simple matter.
Thank you very much.

you could add a flag inside red arrow condition then check for it before moving on to orange arrow.

Thank you. I tried flag but it does not work. I do not really know how to do this correctly. If you or anyone can share a small example then please do so.
I tried the following:

if (K[0] <= 80 && K[0] >= 70)
{
if (CrossBelow(Stochastics(PeriodD, periodK, smooth).K, 80, 1))
RedFlag = true;
DrawArrows(2, 9); // Red arrow
}
else if (K[0] <= 70 && K[0] >= 60)
{
if (CrossBelow(Stochastics(PeriodD, periodK, smooth).K, 70, 1))

if RedFlag == false
DrawArrows(2, 4); // Orange arrow
OrangeFlag = true;
}
RedFlag = false;
OrangeFlag = false;

Thank you in any case.

How about using K[1] ?

Code

                            
if (K[0] <= 80 && K[0] >= 70){
  if (CrossBelow(Stochastics(PeriodD, periodK, smooth).K, 80, 1))
    DrawArrows(2, 9);  // Red arrow}
  else 
    if (K[0] <= 70 && K[0] >= 60) {
      if ( (CrossBelow(Stochastics(PeriodD, periodK, smooth).K, 70, 1))  && (K[1] < 70 || K[1] >80))
        DrawArrows(2, 4); // Orange arrow
}

}

Almost works but still getting double arrows at some places and no arrows at other places where there used to be an arrow.
Thank you.

Try to put some print (with Print() ) some values before each DrawArrows(), it will help you to find what's wrong in your logic.
With only a small part of the indicator, it's hard for us to find what could be wrong.

Hello Sam,
First, I truly appreciate your help.
If you have time and will please see attached compiled .cs file. I'm using 6E 300 volume chart for my testing. There are many double arrows with the approach you have suggested. It is impossible for me to figure out what is wrong and how to fix it. If you can please help. If not then I still truly thank you very much.

Do you really need CalculateOnBarClose = false ?

The way this indicator is coded currently you could get multiple draw object painted on the chart for each 300 volume bar as the COBC = false setting analyzes your code on each incoming tick. I would think you want to set COBC = true so that your criteria is checked each time a bar completes. Not sure what you are trying to do so I can only speculate this might alleviate the problems you are seeing...

Hope this helps,
