I got it !
Thanks a lot !!

@vyacheslav_b perfect. It wasnt obvious to me that single pass was meant by that. Thank you

@scalpingaf Correct, all trades (buy or sell) are taken at the open of the next day you take the decision.

@vyacheslav_b Thank you so much

@support
oh I see now what you mean.
15 strategies PER USER are selected.
At first, I thought you were only going to select 15 strategies total for all users.
Thanks.

@magenta-grimer Hello, you can have at most 50 running submissions in your user area. You can stop any of them any moment and replace it with another one.

Before the end of the Q17 submission phase, you should select at most 15 of them. These will take part to the live contest.

@vyacheslav_b Thank you so much

@alexeigor Hello. Version 0.0.501 of the qnt library works correctly in Colab. Python version support has been extended from 3.10 to 3.13. The basic functionality of the library should work without issues.

To install, use the following command:

Note: Installing ta-lib in Colab is not working for me at the moment.

@theflyingdutchman Hi, sorry for the delay, yes, all fine, more details by e-mail

@sun-73 Yes, we will, sorry for the issue.

@support, thank you for the clarifications. Regards.

@xiaolan That is correct, but the logic can be easily re-used. The only novel element will be the introduction of the liquidity filter at intermediate stages/at the final stage for the selection of the weights.

@antinomy thanks!

@support Thanks for your respond. Now I understand the cause and fixed it

@support Hello. My strategy has the id #16934018 and was submitted in early May, but pnl OS has not been updated yet. Please check this issue. Thank you.

@illustrious-felice Hi, just insist and test other ideas, it is not easy but you will manage!

@illustrious-felice Hello. please look at this post

@newbiequant96 no problem.
I think the issue now is unrelated to the the previous issue. If you can show what is written above return code 1, I can maybe help.
It seems to be an issue in the code.
Regards

@support Thank you !

@vyacheslav_b Thank you so much.

I have one more question for you to answer. I ran the precheck and the result was nan value the first time, but I set the min_date to 2005 - 01 - 01. I would like to ask, why is there a nan value problem? Is it because the ticker I chose had some companies that weren't listed at that time? My strategy id code is # 16767242. Thank you so much
