Hi - I did cheat a bit - wasn't it Monday that CBA went ex-dividend - but even so I thought it was clever that the Gann date I had lined up so neatly. BTW I have found that with other stocks at other times as well.
The problem however is all the Gann turn dates on which nothing happens - I'm definitely still learning here. But if anyone knows how to filter out the nothing dates so I can just act on the prescient ones - I'm listening!
