I Think you're missing the point, CC!
It doesn't matter if Cable falls another 600 pips today. You 'called' the trade 200 pips after the move! That doesn't take any skill. It also puts you in a position where you cant lose in another way: If cable carries on tanking, you can then say 'Look, its down another 100 pips from where I posted it, idiots!'
although, if it rallies sharply from your call, you can get out at ''break even'' and everyone who followed your advice is down 200 lovely pips.
Its worrying that you cant see peoples problems with posting calls 200 pips after the event!
