Any progress or roadmap for Open API v2.0 ?

Hi BeardPower, 

We are currently designing Open API v2.0. Not all decisions have been made yet, therefore I reserve myself to answer your questions at a later stage. However the community's feedback will be taken into consideration seriously during design and development.

Best Regards,

Panagiotis

Protocol buffer doesn't support Python properly, you have to modify it manually and install pure python protocol buffer implementation (because C++ scoping rules ruins Python) to get them work.

pip uninstall protobuf

pip install --no-binary protobuf protobuf

And compile those proto files seperately. I don't know why that's the case.

protoc --proto_path=ctrader/open-api-proto-lib --python_out=ctrader/proto_gen ctrader/open-api-proto-lib/OpenApiModelMessages.proto ctrader/open-api-proto-lib/OpenApiMessages.proto

protoc --proto_path=ctrader/open-api-proto-lib --python_out=ctrader/proto_gen ctrader/open-api-proto-lib/CommonModelMessages.proto ctrader/open-api-proto-lib/CommonMessages.proto

The last problem is how generated Python code import model modules isn't correct. Add relative path by hand to import code as belows

from . import ... as ...

That's how I get it work

I got the answer from customer support. It's not that complex. The unit of swap is shown by pips, not quote currency.

The correct formula is:

swap * 10^(-pip_position) * quantity

1.1 * 10^(-2) * 20 = 0.22
