Max number of trades, but either closing#453

It would be great if there was an option to have a max number of trades option that closes old trades to open new ones. It would by default close the oldest one, but maybe we found have an option to close first the ones in profit, or in loss. The trading group I am using has this problem, that most loss is generated when many trades are opened and the market dumps. And I have the most confidence in the newest positions to generate profit.
