This is a great tool for managers/traders - A filter by currency would enable traders to judge the currency bias of multi currency systems. This filter can be applied at top level , so all stats can be seen. This can be used to decide asset allocation ratios.
In monthly analytics -
1) winner % by currency can be added
2) winner % by trade open hour can be added
3) Sharpe, turn etc.
In summary - $ value gain can be added, just like pips (per currency)
btw, Great job folks.
