error: failed in converting 4th argument `xl' of _slsqp.slsqp to C/Fortran array

Hi guys,

Does anyone know what does the error as title mean and how to get this fixed?

The error occurred whenever I ran the backtesting on IDE using data from 2008 till now. The error would not occur when I started the backtesting from 2009.

Thank you so much in advance.

Regards,
Kelvin

Hi Kelvin, I haven't seen that error before and unfortunately it's difficult to debug without seeing a backtest to reproduce the issue. Could you share the backtest here by attaching it to the post) or opening a ticket with our support team, [email protected]? Thanks.

Hi Alisa,
