I was wondering if anyone knows how to pass data between two or more running cBots.
Eg. One cBot running on the AUDUSD symbol passing data to another cBot on NZDUSD to help in triggering an event.
Thanks.
Static variables would work wonders for you.
Static variables are shared across multiple instances of the same indicator on different charts, so hopefully they would also be shared between bot instances of the same bot.
However, they probably won't be shared between different bots.
It'll save the hassle and slowness of reading/writing files to/from the file system.

Hello everybody.
I am looking for a good cTrader broker with a good spread on AUDSGD pair. ICmarkets seems very good but they dont accept Canadian citizens. Most of brokers I checked dont offer AUDSGD or have quite high spreads on this pair.
THANKS FOR YOUR HELP
AUDSGD and USDSGD are offered by Pepperstone:
They also use cTrader.
Not 100% sure about them accepting Canadians though.

Only difference is I used Bars instead of MarketSeries. Will give this a go. Thanks :)
that should have been "Bars" and not MarketSeries.
I've updated the code in the example.
If it's still not working, it's something else with your code or what you're doing, so you'll need to post some sample code.

What you need to do is:
1) get the position open time
2) create a timer object
3) when 15 minutes has passed on the timer object, trigger it to call a method. That method could be the close method, which closes your position.
Examples for the C# timer object:
https://docs.microsoft.com/en-us/dotnet/api/system.timers.timer?view=netcore-3.1
and

Example code for quick tip:
public override void Calculate(int index)
{
int altIndex = index;
altIndex = Bars.OpenTimes.GetIndexByTime(Bars.OpenTimes[index]);
//Reference any values from a different timeframe with the altIndex
double median = (Bars.HighPrices[altIndex] + Bars.LowPrices[altIndex]) / 2;
Result[index] = median;
}
Hope this helps :-)

Have you looked at the online guides @Spotware have posted?
https://help.ctrader.com/ctrader-automate/guides/trading_api
As for me, I went the cTrader route because it uses C#, which to me is easier because I already knew it. :-)
MT5 will definitely have more support and more options available though because that seems to be the standard in the industry MetaTrader.
If you plan to do any other kind of programming other than for bots/indicators (eg, writing your own Windows applications or whatever), then you should learn C#; otherwise it's up to you.

This is relatively easy.
See code example below. You'll obviously have to make adjustments for it to fit in your code.
//you need to set this up as a parameter
StopBotWhenLossesFallBelow
double _runningTotalsGainLoss;
string _positionLabel;
private void Positions_Closed(PositionClosedEventArgs args)
{
//Only run this method if it's this instance that closed.
Position p1 = args.Position;
if (p1.SymbolName == Symbol.Name && p1.Label == _positionLabel)
{
//Now get the historical trade stuff.
HistoricalTrade ht = History.FindLast(p1.Label, p1.SymbolName, p1.TradeType);
//Running Totals
_runningTotalsGainLoss += p1.NetProfit;
Print("PC20: Running total for \"{0}\": {1}", p1.Label, String.Format("{0:$#,###.00}", _runningTotalsGainLoss));
if (_runningTotalsGainLoss < StopBotWhenLossesFallBelow)
{
Print("WARNING! Running total {0} has fallen below StopBotWhenLossesFallBelow {1} threshold! Stopping bot for \"{2}\"!", String.Format("{0:$#,###.00}", _runningTotalsGainLoss), String.Format("{0:$#,###.00}", StopBotWhenLossesFallBelow), p1.Label);
Stop();
}
}
}

Serialize it to JSON, save the JSON to a text file.
Then when you restart and restart your bot/indicator, in the OnStart or Initialize methods, you can read the json back in and convert it back to a 2-dimensional array.
Example code:
//In the OnStart method:
// read saved file into a string and deserialize JSON to a type
RobotInfoClass ric = null;
if (System.IO.File.Exists(_savedFilePath))
{
ric = JsonConvert.DeserializeObject<RobotInfoClass>(System.IO.File.ReadAllText(_savedFilePath));
System.IO.File.Delete(_savedFilePath); //clean up since we no longer need it
}
///////////////////////////////////////
//In the OnStop method:
using (System.IO.StreamWriter sw = new System.IO.StreamWriter(_savedFilePath))
{
using (JsonWriter writer = new JsonTextWriter(sw))
{
RobotInfoClass ric = new RobotInfoClass();
ric._positionEntryPricePoints = _positionEntryPricePoints;
ric._positionEntryPriceTimes = _positionEntryPriceTimes;
ric._breakEvenPoints = _breakEvenPoints;
ric._increasePositionSizePoints = _increasePositionSizePoints;
//blah blah blah
ric._savedTime = DateTime.Now;
JsonSerializer serializer = new JsonSerializer();
serializer.Formatting = Formatting.Indented;
serializer.Serialize(writer, ric);
}
}

HI Stephan:
I find this easiest to do is code up your reference DLL in the "documents \ calgo \ sources" folder.
When it compiles there:
Then in cTrader in "Automate", select the Indicator/bot you want, and from the 3 vertical dots, select the option to "Manage references":
Then you should find it under the "Libraries" side menu. If it's not there, click the "browse" button in the top right of the window and add it in.
Lastly, launch your visual studio project and viola, it'll be included.
I've had too many issues if I try and go the other way -- adding the reference from within VS without doing it through cTrader.
Hope this helps!

hi I need to print "ok"
print ("ok");
when the price is 60 pips above the current price
thanks
Get Symbol.Bid or Symbol.Ask price (whichever one you want to measure from) and then add 60 pips:
Symbol.Bid + (60 * Symbol.PipSize)
Symbol.Ask + (60 * Symbol.Pipsize)

Hi
I have built a robot with several signals independent of each other, with a different label per signal.
for example :
RobotID_A1
RobotID_A2
RobotID_A3
RobotID_A4
so 4 positions are possible together
I would like to limit to 2 open positions (the robot chooses the 2 best signals depending on the market)
but how to proceed with different labels.
cordially.
Your question doesn't make sense and isn't clear.
What do you want to happen?

Symposium said:
Firemyst... Are you serious?...... 15 Indicators on any chart is your issue!..... Not Spotware's..... They have added a delete button to the Indicators popup panel....
<Left click>, <Right click>.... Indicator Gone!..... Makes removal of any unwanted Indicators simple. A great update to the Platform. The only other Platform (Retail) even on the same page as Ctrader is TradingView's
TWB
TWB: you missed the point. The number of indicators is irrelevant. It's the number of clicks users have to go through now for indicators cTrader doesn't allow you to click on to remove, that provides valuable information or functionality cTrader lacks.
Let's say you have just two indicators. Or better yet, let's just say one. Use the example one I linked to above.
Add it to your chart.
Now see how you can delete it without going through an indicator's menu.
I rest my case.
There are numerous indicators out there like this people use.
It now takes more time for users to accomplish the same action than previously.
That's not good UI design principles.
PS: if you think Trading View is the only other app, you obviously haven't looked at Pro Real Time or ThinkTrader. :-)

Hi firemyst,
You can edit/delete an indicator if you just right click on it inside the chart.
Best Regards,
Panagiotis
Hi @Panagiotis:
As a follow up, you can't do this with every indicator, which makes it even worse.
For example, here's one it can't be done with:
https://ctrader.com/algos/indicators/show/2209
Add it to your chart, and see if you can "right-click" to edit the properties or delete it.
Now imagine you have that on your chart with a few other indicators like PSAR and BollingerBands.
You can't do anything with unless you go through double the amount of mouse clicks introduced in v3.8 as opposed to v3.7.
It's frustrating the end user experience.

I don't know if there's an indicator for it, but you'll need C# code to find "peaks and troughs".
Doing a Google search will yield results for you.
