Hi Darek,
Level II pricing is a feature that will be available in future versions of cAlgo. The website had published material a bit early in this case. We've removed the reference to Level II pricing from the site, and will put it back up when it's ready.
Thanks for your question, and please let us know if there's anything else we can help you with.

Hi
Can you please explain to us what exactly are you experiencing?Is this happening when you use and indicator or a robot? Do you use any complicated robot/indicator that does a lot of calculations? How many instances of indicator/robots have you got opened at the same time?
As i understand you want this indicator to produce one more line with different period. Most probably the code below will do the trick for you:
using System;
using cAlgo.API;
using cAlgo.API.Indicators;
namespace cAlgo.Indicators
{
[Indicator(IsOverlay = false)]
public class cmo : Indicator
{
[Parameter]
public DataSeries Source { get; set; }
[Parameter("CMOSlow",DefaultValue = 20)]
public int CMOSlow { get; set; }
[Parameter("CMOfast",DefaultValue = 9)]
public int CMOfast { get; set; }
[Output("CMOfast",Color = Colors.Yellow)]
public IndicatorDataSeries cmo1 { get; set; }
[Output("CMOslow",Color = Colors.Red)]
public IndicatorDataSeries cmo2 { get; set; }
double downs,downs2;
double ups,ups2;
private IndicatorDataSeries ddown;
private IndicatorDataSeries dup;
protected override void Initialize()
{
ddown = CreateDataSeries();
dup = CreateDataSeries();
}
public override void Calculate(int index)
{
if(index==0)
{
ddown[index]=0;
dup[index]=0;
return;
}
ddown[index] = Math.Max(Source[index-1] - Source[index],0);
dup[index] = Math.Max(Source[index] - Source[index-1],0);
downs=0;
ups=0;
downs2=0;
ups2=0;
for(int i=index; i > index - CMOfast; i--)
{
downs += ddown[i];
ups += dup[i];
}
for(int i=index; i > index - CMOSlow; i--)
{
downs2 += ddown[i];
ups2 += dup[i];
}
if (Math.Abs(ups + downs) < double.Epsilon)
{
cmo1[index] =0;
cmo2[index] =0;
}
else
{
cmo1[index] = (100 * ((ups - downs) / (ups + downs)));
cmo2[index] = (100 * ((ups2 - downs2) / (ups2 + downs2)));
}
}
}
}

Hi
You can use the following example if you want to output data to a text file:
using System;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.Indicators;
using System.IO;
namespace cAlgo.Robots
{
[Robot]
public class WriteToFileExample : Robot
{
StreamWriter _fileWriter;
double avspread = 0;
double spreadnow = 0;
double sum = 0;
int ticker = 0;
int once = 0;
int counter =0;
protected override void OnStart()
{
var desktopFolder = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);//getting location of user's Desktop folder
var filePath = Path.Combine(desktopFolder, "ServerTimeExample.txt");
_fileWriter = File.AppendText(filePath);//creating file
_fileWriter.AutoFlush = true;//file will be saved on each change
}
protected override void OnTick()
{
_fileWriter.WriteLine("Server Time: " + Server.Time);
}
protected override void OnStop()
{
_fileWriter.Close();
}
}
}

Hello
You can use the following code to express that the Bollinger Bands have tightened up:
[Parameter]
public DataSeries Source { get; set; }
[Parameter(DefaultValue = 20)]
public int Period { get; set; }
[Parameter(DefaultValue = 2.5)]
public double bbSTD { get; set; }
[Parameter("MA Type", DefaultValue = MovingAverageType.Exponential)]
public MovingAverageType MAType { get; set; }
[Output("Main")]
public IndicatorDataSeries Result { get; set; }
BollingerBands bbands;
protected override void Initialize()
{
bbands = Indicators.BollingerBands(Source,Period,bbSTD,MAType);
}
public override void Calculate(int index)
{
if( bbands.Top.IsFalling && bbands.Bottom.IsRising ){
//Code Logic goes here
}
}

Hello again,
Can you please try to download this indicator too: /algos/show/124, build it and then try to build the adaptive center of gravity(AdaptiveCG)?
