trade example on main page vs. trade example in "examples" folder

[el-arma]

Hi,

I know it is a purely cosmetic change but the trade example form main page (https://github.com/pawelkn/xapi-python) won't work ( "from xapi import TradeCmd, TradeType" is missing).

In the "examples" folder it works perfectly. Please consider, switching it.

Kind Regards,
