New indicator not importing.

[Alpha23-Ltd]

Hi,

I have created a new indicator (see code below), both the .pyx and .pyd files.
I do make build after this and the .so and .c files are created. So Cythonize seems to be working. There are no error messages.

In my strategy .py file I am not able to import the Indicator as per this line:

from nautilus_trader.indicators.weighted_mid import WeightedMid

I dont think it's a problem with the code, since even if i duplicate an existing indicator and rename it, it still wont import.
Do the Cython indicators need to be declared elsewhere?

thanks

I see the issue is closed, were you able to solve the problem in the end?

Yes. The autocomplete in Pycharm made it look like it wasn't importing but it did once I referenced the module in the code.

Thanks

Cython doesn't seem to play so nicely with PyCharm at times, particularly imports and definitions.
