PAN ANDEAN RESOURCES - EL DORADO.......HUGE FIND

Any of the experts got any thoughts on a "recovery stop loss strategy" for a situation like PRE.

I normally put a 20% SL on AIM and follow it scrupulously except for PRE (dammnit).

Now I am below my stop but want to manage my downside so if PRE goes up, sticks or falls a little - I hold. If is slips unreasonably - I sell. Question is what is unreasonably and How do I monitor it?

I am thinking about a 10% trailing stop until I get back inside the 20% envelope.

This seems reasonable but with % losses costing much more than % gains earn I would appreciate one of those "hard head" aphorisms like "let the trend ....." if there is one to cover this situation.

I realise I have made all the newbie mistakes with PRE but I Just KNOW that as soon as I sell the price will triple.
