Hi,
Just tested it with the code you posted, worked fine on my system, the popup showed up and I got a message on Telegram.
Did you made any kind of change on the code? or you used the same exact posted code?
I noticed the following in the error text. In the very first line of the log
.....Culture=neutral, PublicKeyToken=null]]. The value ' ' cannot be parsed as the type 'Int32'.
It turns out that he passes NULL instead of a token, and then he tries to pass the value " ", converting it to Int32 (Failed and an error is thrown )
No, that's not the case.
It looks like something is going wrong in de-serialization.
I recorded a video that shows it's working fine on my system:

RE: RE:
tippy said:
ok, it seems to work well on your system.
Could you please check missing trendbar with timestamps?
request.fromTimestamp = 1578362820*1000 # 2020-01-07 02:07:00 GMT request.toTimestamp = 1578363000*1000 # 2020-01-07 02:10:00 GMT
The bar data can be missed if there was no incoming price during that bar period, so it looks like the price didn't changed from previous bar close to this bar close.

RE: RE:

thanks for response. I have noticed that first run is ok, problem occurs after another execution. Could you try execute sendProtoOAGetTrendbarsReq multiple times and check if it is ok?
I have another issue, is it normal that some of trendbars are missing in historical data for EURUSD on M1? I am using a demo account from the IC Markets.
Hi,
I tested sendProtoOAGetTrendbarsReq by calling it 5 times in a row, here is the result:

def sendProtoOAGetTrendbarsReq(weeks, period, symbolId, clientMsgId = None, numberOfCalls = 0):
if numberOfCalls == 5:
return
request = ProtoOAGetTrendbarsReq()
request.ctidTraderAccountId = currentAccountId
request.period = ProtoOATrendbarPeriod.Value(period)
request.fromTimestamp = int((datetime.datetime.utcnow() - datetime.timedelta(weeks=int(weeks))).timestamp()) * 1000
request.toTimestamp = int(datetime.datetime.utcnow().timestamp()) * 1000
request.symbolId = int(symbolId)
deferred = client.send(request, clientMsgId = clientMsgId)
deferred.addErrback(onError)
numberOfCalls += 1
sendProtoOAGetTrendbarsReq(weeks, period, symbolId, clientMsgId, numberOfCalls)
Regarding missing data, no, its not normal, most probably something is wrong with your code.
Please check the limits on documentation: https://spotware.github.io/open-api-docs/messages/#protooagettrendbarsreq
If you ask for more data than allowed you have to send multiple requests.

I think I'm misunderstanding something.
So far I only run bots on the automate section charts.
Is there a way to run a bot I developed on the regular, trading section chart?
Hi,
Yes, you should use the regular trade charts for running cBots, not the automate section.
To run a cBot click on cBots icon:

Hi,
The new event args gives you all the chart objects that were updated, not just one object, because multiple objects can be updated at the same time.
To find the object that you are looking for you can use Linq, ex:
private void Chart_ObjectsUpdated(ChartObjectsUpdatedEventArgs obj)
{
var verticalLine = obj.ChartObjects.FirstOrDefault(iObject => iObject.ObjectType == ChartObjectType.VerticalLine
&& iObject.Name.Equals("VerticalLine_name", StringComparison.OrdinalIgnoreCase));
if (verticalLine != null)
{
}
}
Here I check if there is an updated object that's vertical line and its name is "VerticalLine_name", if there is such an object we will get it otherwise the result will be null.

Hi,
I tested on our QuickFIXn console sample, I subscribed to 200 symbols and waited for an hour, no disconnection and it's still running.
To subscribe on multiple symbols on console sample change the code of its ExecuteAction method to this:
private static async void ExecuteAction(char action, string[] fields)
{
switch (action)
{
case '1':
SendNewOrderSingle(fields);
break;
case '2':
SendCancelOrder(fields);
break;
case '3':
SendReplaceOrder(fields);
break;
case '4':
//SendMarketDataRequest(fields, true);
for (int i = 1; i < 200; i++)
{
SendMarketDataRequest(new[] {i.ToString(), "n"}, true);
await System.Threading.Tasks.Task.Delay(1000);
}
break;
case '5':
SendMarketDataRequest(fields, false);
break;
case '6':
SendOrderMassStatusRequest(fields);
break;
case '7':
SendRequestForPositions(fields);
break;
case '8':
SendSecurityListRequest(fields);
break;
case '9':
SendOrderStatusRequest(fields);
break;
}
}
Then enter this command: 4|1|n

Hi,
I just tested the console app, I created a new copy of sendProtoOAGetTrendbarsReq method and called it from original one, the code looks like this (line 186):
def sendProtoOAGetTrendbarsReq(weeks, period, symbolId, clientMsgId = None):
request = ProtoOAGetTrendbarsReq()
request.ctidTraderAccountId = currentAccountId
request.period = ProtoOATrendbarPeriod.Value(period)
request.fromTimestamp = int((datetime.datetime.utcnow() - datetime.timedelta(weeks=int(weeks))).timestamp()) * 1000
request.toTimestamp = int(datetime.datetime.utcnow().timestamp()) * 1000
request.symbolId = int(symbolId)
deferred = client.send(request, clientMsgId = clientMsgId)
deferred.addErrback(onError)
sendProtoOAGetTrendbarsReq2(weeks, period, symbolId, clientMsgId)
def sendProtoOAGetTrendbarsReq2(weeks, period, symbolId, clientMsgId = None):
request = ProtoOAGetTrendbarsReq()
request.ctidTraderAccountId = currentAccountId
request.period = ProtoOATrendbarPeriod.Value(period)
request.fromTimestamp = int((datetime.datetime.utcnow() - datetime.timedelta(weeks=int(weeks))).timestamp()) * 1000
request.toTimestamp = int(datetime.datetime.utcnow().timestamp()) * 1000
request.symbolId = int(symbolId)
deferred = client.send(request, clientMsgId = clientMsgId)
deferred.addErrback(onError)
Then I sent a ProtoOAGetTrendbarsReq with these parameters: 1 D1 1
Here is the response:

slukk200 said:
I just tried it with 5 symbols, and it has been working perfectly for 2 hours so far.
-Is there a limitation on how many symbols can I connect to or how many messages can I recieve?
-Or maybe there are some limitations of the demo accounts?
-Should connect to one symbol per session only and have 80 different sessions?
-ReconnectInterval=900000, I see that people usually set it to around 20. Could this be the problem?
Unfortunately I couldn't find anything about limitations in the document, so if anyone knows anything about it, please share.
Hi,
I'm not aware of any limitation on number of symbols you can subscribe.
Maybe you are not processing fast enough the incoming data and your buffer gets overflow.

Hi,
You can't check/uncheck the outputs with code.
Hi, thanks for your reply.
Is there, at least a way I can change Output Thickness?
If I cant uncheck output with code, maybe I can change Output line thickness to 0, it is possible?
Hi,
Right now you can't change any of the output properties programmatically, to hide an output you can set its value to double.NAN.

RE: Code is crashing cTrader
jani said:
Hello,
I tried to use below in an indicator:
Print("{0} bar on the chart. Loading 10 000 bars", Bars.Count); while (Bars.Count < 10000) { var loadedCount = Bars.LoadMoreHistory(); Print("Loaded {0} bars", loadedCount); if (loadedCount == 0) break; } Print("Finished, total bars {0}", Bars.Count);and it practically crashed my cTrader every time I compiled the code while the indicator was attached to a 1H chart.
Hi,
I just tested your code on Spotware cTrader beta for EURUSD and GBPUSD H1 and it worked fine.
But there is an issue with your code, what if the symbol doesn't have that number of bars? then you will end up with an infinite loop which will crash your cTrader.
You don't know how many bars are available, so if you use a fixed number and symbol doesn't had that number of bars then it will crash your platform.

Hi,
You don't have to use this library for sending alerts to Telegram, you can use the Telegram .NET library that I mentioned on my first post.
You can also code the whole API interaction by yourself, you don't have to use any library, but they will make it much easier for you.
