RE: It seems Bars.LoadMoreHistory() has been recently broken and doesn't work
firemyst said:
Have you considered that there might not be any more history to be loaded, especially if you're not scrolling to the left on the charts?
See this thread:

Hello Firemyst,
Thanks for your reply.
This function obviously has changed its behavior, because I had an indicator and source control of it and it had working fine for a long time, debugging it led me to find this problem. Regardless of the broker or pair it returns zero and another user had this issue too but check more on this.
See video attached, first it counts bars without using the function on AUDNZD, then I run it again using the function, it turns into a locked refresh loop (doesn't even print the bars until after it loads the data, doesn't even print the initial bar count), at the end it does increase the number of bars but the function still returns zero.
Before this problem, we were able to control how many bars to load in a simple while loop synchronously without issues.

Hello cTrader,
On a relatively recent update, you've added LocalStorage in order for us to avoid setting AccessRights to full access, and this is a great addition.
However, if for some reason the name of the files are not known, we cannot delete them.
I would appreciate for this small change to the API, give us a function to get all filenames, or also delete all files from LocalStorage.
Regards,
@Waxy

Hello Spotware, thanks for these fixes and changes.
For the logs, would you please add back these 2 also:
- The lines are missing, now there's no distinction between each message and it makes it hard to read.
- Now you cannot sort columns by dates, type or message alphabetically. (because there are no columns anymore)

Hello Panagiotis,
I'm experimenting something with Ajay also and I don't have a crash, but I have an inconsistent behavior, here's a simple code, it doesn't crash, but while it is shown perfectly on Windows (with a few differences between versions), it's not visible on Mac at all.
Here's a code sample:

Hello Panagiotis,
This doesn't seem to address the inconsistencies between the different Windows versions, it shouldn't crash this way.
Besides, is there other way to put this control above the ask line besides negative margin? I will try with Canvas Top/Bottom and get back when I'm able to test it.
I have seen other size and margin inconsistencies that are not using negative margins, if possible to replicate I'll attach it here.
Thanks for your reply.

I figured out how to debug with rider.
"Settings | Build, Execution, Deployment | Debugger" and click "Set Rider as a default debugger"
It should prompt you to use Rider for debugging.
Allow JIT Rider Debugging Session to be Started with Debugger.Launch() : RIDER-18701 (jetbrains.com)

RE: cTrader randomly crashing
Hello Panagiotis,
The only thing the log says is “CbotName” crashed
As for sending the code, can I share it via email? The code is private, and I cannot share it publicly.

Hi Waxy,
Can you share the cBot's code and log after the crash as well?

Hello,
Here's a sample, just any reference to fractals makes it print the values, something that didn't happen before 4.8.27.
using cAlgo.API;
using cAlgo.API.Indicators;
namespace cAlgo;
[Indicator(AccessRights = AccessRights.None, IsOverlay = true)]
public class FractalsIssue : Indicator
{
private Fractals _fractals;
protected override void Initialize()
{
_fractals = Indicators.Fractals(5);
}
public override void Calculate(int index)
{
var _ = _fractals.UpFractal[index];
}

You can change the values of these parameters at runtime, this is why they have "set" accessors, you can change their values.
This Prints:
Hello World
Hello World2
using cAlgo.API;
namespace cAlgo.Robots;
[Robot(AccessRights = AccessRights.None)]
public class NewcBot : Robot
{
[Parameter(DefaultValue = "Hello world!")]
public string Message { get; set; }
protected override void OnStart()
{
Print(Message);
Message += "2";
Print(Message);
}
}

Just for the record, I have fixed it by deleting all sessions from cTrader session and logging in again, this can only be done via web.
