The current spotware cAlgo version is 1.0.299. If you merely restart it, it should update automatically, otherwise you will see a message on the top right corner that an update is available.
If you want to download it again it is found on the homepage of cTDN. Just click the green "Download cAlgo Demo" button (bottom, middle of the page).

RE:
Also, is there a way to count the number of active positions/orders with same label?
For positions in the account:
var count = Account.Positions.Count(position => position.Label == "1234");
For pending orders in the account:
var count = Account.PendingOrders.Count(order => order.Label == "1234");

You may create a custom indicator that references the MACD and the Stochastic and outputs their results then their output will be on the same panel. If you need help learning how to do that refer to the sample indicators that are included in cAlgo, like SampleAlligator for instance references MedianPrice and WellesWilderSmoothing Indicators.

You may create another indicator that references the midrange indicator you created:
//#reference: midrange.algo
// -------------------------------------------------------------------------------
//
// This is a Template used as a guideline to build your own Robot.
// Please use the “Feedback” tab to provide us with your suggestions about cAlgo’s API.

// -------------------------------------------------------------------------------
using System;
using cAlgo.API;
using cAlgo.API.Indicators;
namespace cAlgo.Indicators
{
[Indicator(IsOverlay = false)]
public class NewIndicator : Indicator
{
SimpleMovingAverage sma;
midrange mrange;
[Parameter(DefaultValue = 10)]
public int Period { get; set; }
[Output("Main")]
public IndicatorDataSeries Result { get; set; }
protected override void Initialize()
{
mrange = Indicators.GetIndicator<midrange>();
sma = Indicators.SimpleMovingAverage(mrange.Center, Period);
}
public override void Calculate(int index)
{
// Calculate value at specified index
Result[index] = sma.Result[index];
}
}
}

Hello,
The ability to add the stop loss and take profit as well as slippage for market orders will be available in the next release. You may look at the description for the time being on how you can implement it here:

Position.Label and PendingOrder.Label
Label
A Label is an identifying string, associated with an order or position. One can specify a label using the new request-based API for creating orders; in that case the created order will have the specified label. When the order is filled, the resulting position will also have the same label.
Example 1:
protected override void OnBar()
{
var request = new MarketOrderRequest(TradeType.Buy, 10000)
{
Label = "MarketOrderLabel"
};
Trade.Send(request);
}
protected override void OnPositionOpened(Position openedPosition)
{
Print("Position Label is {0}", openedPosition.Label);
}
Example 2:
protected override void OnStart()
{
double targetPrice = Symbol.Ask + 10 * Symbol.PipSize;
var request = new StopOrderRequest(TradeType.Buy, 10000, targetPrice)
{
Label = "1234"
};
Trade.Send(request);
}
protected override void OnPendingOrderCreated(PendingOrder newOrder)
{
Print("Order Label is {0}", newOrder.Label);
}
protected override void OnTick()
{
foreach (var position in Account.Positions)
{
if (position.Label == "1234" && position.GrossProfit < 0)
{
Trade.Close(position);
}
}
}

RE:
I noticed earlier robots turning themselves off. It appears that its happening when a new candle is generated. All roborts for the same candle period switch off. Also When I rebooted the application the Symbol for the Robot is not appearing in the menu. It appears they are no available at all now
Hello,
Try the following:
Clear the cache (delete all files) from this folder:
C:\Users\...\AppData\Roaming\xxx-cAlgo\Cache
(You may find the AppData folder by searching for %appdata%, i.e. in Start -> type %appdata% in the search box)
Let us know if this helps.

RE:
The documentation does not tell anything about calling the methods of an external C/C++ library (dll).
- Does it work at all? (e.g. using P/Invoke)
- Where should the external dll be copied to?
- When would this information (along with some short tutorial) be added to the documentation?
What kind of protection do you provide for the robots/indicators? Is there any tutorial about it?
See this example for P/Invoke and external dll calls:

This example displays a pop up message box.
using cAlgo.API;
using cAlgo.API.Indicators;
using System;
using System.Runtime.InteropServices;
namespace cAlgo.Robots
{
[Robot]
public class PInvokeExample: Robot
{
[DllImport("user32.dll", CharSet = CharSet.Unicode)]
public static extern int MessageBox(IntPtr hWnd, String text, String caption, uint type);
protected override void OnStart()
{
MessageBox(new IntPtr(0), "Hello World!", "Hello Dialog", 0);
}
}
}

RE:
please can you tell me how to add news robot after download , i have downloaded it but i was not be able to add it , please i need your help .
Move the News Robot.cs (after extracting from the zip) file in the robots location.
The easiest way to access this location is from the robots list in the left panel in cAlgo. Click on the drop down arrow and select "Show in Folder".
Then you just need to build the robot and you should be able to run it by adding an instance.
You may also read the instructions here: /algos/robots -> click on the "How to install" link.

RE: RE:
admin said:The .algo file is not currently encrypted. There is a plan to encrypt the .algo files in the future though, therefore they will be protected against reverse engineering.
How about the external dll calls?
Hello,
To add a reference please use the "Add Reference" button on the top menu next to build. You may then locate the dll in your file system and add to your robot/indicator.

Thank you for the suggestion. We will think about adding such a feature in the future.
