Rounding

[pman777]

I need to round a variable (currLine double) to the nearest tick ... eg, the value 804.38648328337 needs to get rounded to 804.4. Below is the code I use to calculate this variable.


currLine = (HMA(10)[0] - (ATR(20)[0])

Hello pman777,
You can use the RoundToTickSize function to round the value of your variable to the nearest ticksize. Please refer to our help guide to know more about it.

thanks ... can you show me how to use this function within a coding example

Hello pman777,
A sample code will be like:

currLine = this.Instrument.MasterInstrument.Round2TickSize(HMA(10)[0] - ATR(20)[0]);

Please let me know if I can assist you any further.

that worked ... thank you.

Now I'm trying to shade a region on my chart from my currLine to (currLine + 5*TickValue) but I get an error message ... seems currLine needs to be a 'series' ... not sure how to convert it into a series ... can you assist?

Here's my code:
DrawRegion("tag1", CurrentBar, 0, currLine , (currLine + 5*TickValue), Color.Empty, Color.Lime, 2);

Hello pman777,
You cannot convert a double to a IDataSeris. If you want to draw a region then you have to store the values in a DataSeries.

//in variable
DataSeries ds;

//in Initialize
ds = new DataSeries(this);

//in OnBarUpdate
ds.Set(Instrument.MasterInstrument.Round2TickSize(HMA(10)[0] - ATR(20)[0]));

//draw the region
DrawRegion("tag1", CurrentBar, 0, ds , ds[0] + 5*TickValue, Color.Empty, Color.Lime, 2);
