I only use ropes in the H4 timeframe... you can try lower timeframes.. H1.. but I don't recommend you less than 30M...
instead of entering when the wall crosses 20 or 80 levels... just look for divergences between price and the wall... wait and see.... if it reverses finally you will have the entry at the cross of 50 level. only if it is still a rope there... if not.. it may turn again and continue with the trend... I will be back in middle October... and will try to create a journal of this strategy explaining each trade. I find this very powerful combined with the divergences. check divergences thread also http://www.forexfactory.com/showthread.php?t=87088
