RE:
Hi
Yes, I can navigate to the folder, however:
1. On my computer there are only version 6.0.8 and up, no 6.0.0
2. More importantly, I don't know how to change the version of the framework. It seems the framework properties is read only, there is no edit/add/remove option.

RE:
Hi
I understand that. I also updated the original post and uploaded screenshots of the versions of the references. It seems that when a new cBot is created it uses version 6.0.0.0 which is old. Is there a way to make a new cBot to automatically use the highest version available?

RE:
Thank you,
I've done the changes described in the link you provided so now I can use Winforms on my cBot. However, when I added a reference to my old dll which is called utils I got the following error:
I also added a screenshot of Windows.Forms refereces both from the cBot and the utils. I can see there's a difference but I'm not sure how to fix it without making a problem. It's also prefered that the cBot will use the newer version inseatd of Utils to use the loder one.

RE:
Hello and thank you for your reply.
I was able to solve the issue by making a few small changes in the ScrollChart method. I tried to apply it to your version of the indicator however there were sync issues when 2 charts are changed at the same time so I let it go. I am uploading my fixed version of the indicator, feel free to use/improve/share it with the community. If there are any updates or improvements on the subject please let me know.

RE:
Starting at an earlier date solves the problem but it's far from being an easy solution as described above.
A low priority means it will never be solved, it's open for a year and a half already. I don't see why this issue cannot be solved sooner, the feature already exists on a live run.
Thanks

They happened during a simple 'ModifyStopLossPrice' which always works fine, including on the day of the errors, until the errors occured.

RE: RE: RE: RE: RE: RE: RE:
My original single symbol cBot has dozens of private members (strings, integers, etc.). All those members were designed for a single symbol. Now that there are many symbols, each of them should have a different value per symbol. Is there an easy straight forward way to convert all the members from single to multi symbol?
Thanks
