This is a continual struggle to take reasonable losses when themarket presents them. This morning during the Tokyo session, there was a very clear buy signal but I didn't take it because of my clouded judgement holding a position left over from yesterday.
Resolution: to trade the bands for exits. Yesterday should have had 3 losses and 6 wins. Instead I had 3 buys and all exited break even on the following day. No profit to speak of.
As the AA guys like to say: it works if you work it.
