Get dashboard trade stats by group mask

GetDashboardTradeStatsByGroupMask¶

Returns trade totals for accounts in the selected groups.

{"group_mask":"*"}

{"total_trades":720,"total_profitable_trades":310,"total_pnl":15700.0,"total_commission":-560.0,"total_swap":-120.0}

This is the only split dashboard method that currently traverses trade statistics. Other widgets do not wait for this calculation.
