Stock fund simulation disk two financial matching stock trading exchange system source code download

After I built this program, I didn't log in to the frontend, so I don't know if it's a problem with the build or with the source code itself.

There's also a problem with nan, presumably the data is not being captured (that said, what task is supposed to be performed here to capture the data, and I can't find it)

People need to be aware of this and if they feel they are capable of handling the above before buying
