DrawText for a calculated value?

[BigRo]

Hi, i would like to print a number on the chart just like i do with drawtext() but this number should be calculated, for example the current diffrence between two moving averages. but somehow i cant make it work since drawtext() requires a string so when i use something like

"emaSeries[0]-ema2Series[0]" it will just print that rather than the value.

Hello BigRo,

Thank you for your inquiry.

The reason why it is printing "emaSeries[0]-ema2Series[0]" is because you have wrapped this statement with quotation marks. As DrawText() accepts a string for this parameter, it is just going to output that exact string you have specified.

If you wish to output a value, you will want to create a variable that will hold the value of emaSeries[0] - ema2Series[0] and use that variable with ToString() appended to it.

Example:

double subtractedEMAs = emaSeries[0] - ema2Series[0];

DrawText("tag", subtractedEMAs.ToString(), .....);

Please, let us know if we may be of further assistance.

ok, worked and is there a way to round this number because it has 10-15 decimals for example
0.0008000000000005 or something.

i was tryin to multiply it by 10000 so i would get the pipvalue as real number by using int instead of double but that doesnt seem to work either.

ok got it.
used


double x = 1234.7;
int a; // Cast double to int.
a = (int)x;

System.Console.WriteLine(a); } }
// Output: 1234

Dear ZacharyG,

I tried to implement your idea into my Drawtext, but I get an error. Any idea what I am coding wrong?

Hello kadan,

As a heads up, Zachary is no longer with NinjaTrader.

Please expand the Error column so that we may read the full error message.

What is the full line of code causing the error?

From the screenshot it looks like there are too many parameters used in this overload of DrawText(). There are not any overloads that have string, string, bool.

DrawText(string tag, bool autoScale, string text, int barsAgo, double y, int yPixelOffset, Color textColor, Font font, StringAlignment alignment, Color outlineColor, Color areaColor, int areaOpacity)

Perhaps you are wanting the first string to be concatenated?

"EMA 288 max avg. " + countad.ToString()

Dear ChelseaB,

Concatenate has helped. Thank you very much for your help :-)
