RE: Differences in net profit on screen and in code

Hi lisabeaney,
Can you please provide clear steps to reproduce this behavior? We would need cBot code, broker, account type, backtesting parameters and exact moment we should break the execution.
Best regards,
Panagiotis
Hi,
I've emailed over the code and precise steps to reproduce this problem. I just wanted to check that you had received the email and to ask if there was any update.
Many thanks,

Hi Lisa,
Please share with us the cBot code that would allow us to reproduce this problem, as well as the cBot parameters and broker.

Hi,
If you can let me have your email address I'll send it all through.

I've just changed the code to give AccessRights = AccessRights.FullAccess and it now runs the backtest without a problem…

RE:
Hi Panagiotis,
I've noticed this on v4.3.12 - I have to set all BOT's and Indicators to FullAccess before they will run.... is this a new requirement or a bug that will be fixed ?
Many thanks,
Lisa

RE: Solution is simple
Can you still access your live broker accounts with the version from Spotware ? When I have done this in the past I’ve been limited to a demo account

İndicators were not working after last update on my pc.
i simply uninstalled ctrader on my pc
Downloaded version 4.3 direct from spotware website.
Logged into the ctrader with my credentials
Charts and everything came back 100% working.
Everything works fine for now.
Hope that helps.

This shows the indicators that should be on screen... including the MACD Crossover that is blank. It was working without a problem until teh most recent update.

I have the same problem in the backtesting section of Automate on version 4.2.17. The indicators show up on the Trade section and on the main chart in Automate but they are no longer displayed on the Backtesting tab. I have re-run the back test and they still don't display even though they are listed in the object manager.

I have found the offending code that is causing this error, this will happen to a few of our products.
Leverage = robot.Account.PreciseLeverageThe robot object is passed into the assembly class that displays the UI, all the other events work fine, but when a call is made to retrieve account information, it throws the error below.
Illegal call out of MainThread is detected. Use `BeginInvokeOnMainThread`

RE:
Thank you ! That makes sense knowing how the take profit point is calculated :)
PanagiotisCharalampous said:
Hi Lisa,
This probably happens because of currency conversions. The position's P&L is converted to your account's currency based on the conversion rate of the backtesting's last date. Hence moving the end date back and forth can cause positions having slightly different P&L, resulting to a different overall performance for your execution.

Hi Lisa,
I could not reproduce this behavior and we did not make any change to this. Are you sure this is not related to your cBot?
Best Regards,

It is happening with all our BOTs - this is on IC Markets..
Previously this BOT would have had the full name shown in the Finder Window. It now only shows the short name as shown in the dialog box.

Hello All,
Is there a simple way to licence a cBot, so i.e. the bot would run only on buyers account or buyers machine?
Thank you
Patrick
Yes, you can read the processor ID and then create a hash code from it. Write it to a text file and then check the contents of that file when your BOT runs...
The problem I've run in to licensing a single account is that people quite often have 2 or 3 demo accounts that they use for testing and then a different account for live trading... it can end up a bit messy !
I've ended up writing a licensing BOT that sends the request through to me and then I email the license code to the user, they copy & paste the code in to the License BOT and re-run it to generate the text file that contains the code. Any other BOTS you write can then check the contents of this file.
Hi Lisa, do you mind to share the source code for your licensing bot? Just need some reference. Many thanks.

RE:
It's not a problem when you start the BOT.... but when you close cTrader without stopping the BOTs first you end up with a disorderly shutdown. The protected override void OnStop() Is not triggered. It would be good to have a warning that you still have BOTs running ( II thought this was something it used to do ??) especially because cTrader won't let you switch accounts with BOTs running you do expect it to warn you when you close the program.

Hi Lisa,
The parameter values displayed in the cBot parameters panel are not updated if they are changed from within the code.
Best Regards,
Panagiotis
Hi Panagiotis,
What I'm trying to do is set a variable based initially on the BOT parameter but then updated from the field in the Panel....
ie. take this parameter
[Parameter("Max Buy Positions", Group = "Open Positions", DefaultValue = 8, MinValue = 0)]
public double MaxOpenBuy { get; set; }
public double iMaxBuy, iMaxSell;
Then, when the BOT starts :
protected override void OnStart()
{
iMaxBuy = MaxOpenBuy
}
and then have the iMaxBuy variable updated by the MaxBuy when the user clicks on the "Apply Changes" button.
I know its most probably a really simple thing I'm getting wrong or I've missed but I can't seem to get the iMaxBuy to update !
Many thanks,
Lisa

RE:
PanagiotisCharalampous said:
Hi Lisa,
As far as I can see you are using the Genetic Algorithm as an optimization method. GA introduce randomness between executions therefore execution times are not comparable. Can you reproduce the same behavior using Grid search?
Best Regards,
Panagiotis
Hi Panagiotis,
I understand that the times can vary but in all the optimisations that we ran using the GA on v3.6 we never saw the times vary between 4.5 hrs and 18 hrs using the same bot on the same currency pair using the same test parameters.
Just to make it clear we have seen a 400% increase in optimisation times. We are used to seeing variances with the GA but we have never seen variances of this size before.
Unfortunately we can't try running this on the grid method because we don't have access to v3.6 anymore.
Kind regards,
Lisa

We do not have any other work in progress for this issue. Can you share a cBot that demonstrates this behavior?

I'm assuming you would like the BOT with the code included.... what is the best email address to send this through to ?
We have run the optimisation on the same machine on version 3.6 and 3.7 using the same parameters. The times have gone from 4hr 36min to over 18 hours..
