You can use ZEROMQ is the easy and reliable way to do
here is an example:
Server Side:
using System;
using System.Text;
using System.Collections.Generic;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;
using ZMQ;
List<string> fields = new List<string>
{
"Open",
"High",
"Low",
"Close"
};
protected override void OnStart()
{
int total = 0;
using (var context = new Context(1))
{
using (Socket worker = context.Socket(SocketType.DEALER))
{
worker.StringToIdentity(Symbol.Code, Encoding.Unicode);
worker.Connect("tcp://127.0.0.1:5999");
while (true)
{
string request = worker.Recv(Encoding.Unicode);
if (request.Equals("FIM"))
total++;
// Print(total);
for (int idx = 0; idx < fields.Count(); idx++)
{
if (request.Equals(fields[idx]))
{
var valor_ = valor(request, Convert.ToInt32(worker.Recv(Encoding.Unicode)));
worker.Send(valor_, Encoding.Unicode);
break;
}
}
}
}
}
}
private String valor(string request, int periodo)
{
if (String.Equals(request, "Open"))
return Convert.ToString(MarketSeries.Open.Last(periodo));
if (String.Equals(request, "High"))
return Convert.ToString(MarketSeries.High.Last(periodo));
if (String.Equals(request, "Low"))
return Convert.ToString(MarketSeries.Low.Last(periodo));
if (String.Equals(request, "Close"))
return Convert.ToString(MarketSeries.Close.Last(periodo));
Print("cagada");
return Convert.ToString(0);
}
//////////////////////////////////////
Client Side
protected override void OnStart()
{
using (var context = new Context(1))
{
using (Socket requester = context.Socket(SocketType.ROUTER))
{
requester.Bind("tcp://*:5999");
System.Threading.Thread.Sleep(1000);
double high = consulta(context,requester,"USDJPY","High",100)
}
}
}
private double consulta(ZMQ.Socket requester, string Ativo, String Series, int periodo)

requester.SendMore(Series, Encoding.Unicode);

}
}
you can get zeromq via nuget.. create a new project in visual studio download via nuget and then reference it in your calgo project outside de visual studio,, you do this just to get the files
as clrzmq is a wrapper of the libzmq the libzmq must be in the calgo path... control alt del... the click with the right button on calgo process... then go to file or folder(sorry my windows is in pt-br) something like that.. then copy the libzmq to this folder
This is an example of as many robots as you want exchanging quotes... pay attetion in this topology the router must wait for the dealers to connect... i really sugest you to go to http://zguide2.zeromq.org/
here are my references
//#reference: ..\..\x64\Release\clrzmq.dll
//#reference: ..\..\x64\Release\clrzmq-ext.dll
i hope this helps you

RE:
The error is in this two lines
//Local declaration
TriState _Close_BUY_Positions = new TriState();
TriState _Close_SELL_Positions = new TriState();
You try to instance a object from a class TriState but there is no reference to it! You must use "add reference" and look for the dll file that contains the TriState Class and then declare it.
using TriState or whatever the classname is!"

No support for this. Look this topic
I coding matlab to optimize my parameters, but this is do a work that are already done, ctrader guys must release a method that call the backtest and then we can interact trough my variables to find the best value, but this is not possible right now

Sorry, i think i was not clear. I want to know if its possible to start a backtest from inside a robot
Something like this:
for(var i=1;i>10;i++
results = myrobot.Backtest (GBPJPY, h4, 4500000, i, 54, 10, 1000, 80);
end
This is useful to optimize the value used for the indicators. Is it clear now?
Tks guys

RE: RE: tick charts
jfuechsl said:is there some timeframe when tick charts will be available?
You can use this indicator:
Hello guys!
I need some help here. Im using this tick chart indicator. But when i try to access the values inside a code i fail. For example if i want to get the bid.LastValue
//#reference: C:\Users\Leonardo\Documents\cAlgo\Sources\Indicators\Tick Chart.algo
TickChart ticks;
ticks = Indicators.GetIndicator<TickChart>();
Print("{0}",ticks.Bid.LastValue);
"
I get NaN as return.

What about traders first talk?
Why not have a session to discuss this? This is happening more often, i had the same problem with *MODERATED* with a open position and it goes to stoploss... I complained and they refunded me!
This must be a fair game... I think part of fair things is to everybody to know and follow the rules, we must exchange information about bad broker or bad pratices, and i cannot see a better place than here!
So thinks TRADERS FIRST, not brokers!
