Dislikedwell said but to his defence Indrek was simply answering the question of the poster. be good......................Ignored
They were just facts. So far any rescuing attempt only increases the risk without significantly increasing the reward and this can only keep or decrease the expectancy of the system. Even if it is eventually profitable it is less profitable or exactly as profitable but with more effort. That's against the goal.
Any method one might imagine to rescue a position becomes a trading strategy and can be used standalone. If it works, it is a profitable trading system on its own since you can start with a non losing position. Here the basket is just one example. For this reason it isn't a rescue per se. [Using the loser to save 1 spread is actually a good idea since the basket strategy has a high cost in spread. But the loser is virtually closed for a loss, so not rescued at all]
The answer to the original question "[what is a] practical and feasible recovery method(s) on how to rescue a losing position?" would be "The only possibility is by trading another profitable system". But if you trade another system, the set of the two systems becomes a new system. This third composite system will have its own losers (unless you found HG!). Now how can you save them? By extension you would have to trade an infinity of systems... which isn't possible. Therefore my answer is "I just proved that there exists no feasible method to rescue a losing position".
No greed. No fear. Just maths.
