I don't see the need now, and not sure I understand.
If you mean when would I sell short, .065 is next target.
If you mean when would I stop trading all together, It would be when you can't think of a news event yet to come, or when volumes stay under 10 million for a week .
If you mean when would I sell long, if the chart pattern, up trend channel, is broken out of for 3 days sideways or 2 days retrace or one day dive.
