Automatic compounding of position size

Add an option for signal bots where once some profit has been made, some adjustable fraction of this profit (e.g. 50%, 100%) is added to subsequent positions automatically. It is vital that the profit be spread over the base order and subsequent DCA orders in proportion to their initial relative sizes, so the weightings of the different orders remain the same. The current % of funds option for specifying the base order does not satisfy the requirements I am specifying here, because if an open position is currently maintaining a significant loss/drawdown this method will make any new positions smaller since they are calculated from the total account size including the impact of the unrealised loss. Instead using only the realised profits to facilitate compounding would be far more useful.
