Hi,
Apologies if this has been asked, but what is the best practice for handling Poloniex margin trades?

When i import margin trades it counts the initiation of my long as a btc sell (of which i don't have).

is it recommended to have multiple accounts where you separate out margin and spot trades?

Secondly, when i sell on Polo and transfer to coinbase to sell for fiat, it can't seem to find a basis for my sell.

Thanks for any help in advance...
