Why I did not buy Friday's "Flag" in GDX

If you look at the action in GDX on Friday, without the perspective of the days preceding it, it looks like a perfect flag buy signal. Yet I did not buy and did not send out a buy alert to my subscribers. In fact, I told them not to buy. Why is that? Here is Friday's chart:




There is a nice strong flag pole followed by a nearly perfect looking flag. The volume was right and everything looked good, but only from the perspective of that single day. The top of the flag was bumping up near the resistance of a previous breakdown, but even that doesn't normally stop me from buying a flag.
Here is a little wider view of what happened:




The first chart is contained within the oval on the second chart. Notice how the beginning of Friday's "flag" was actually a breakdown from the original flag pole outlined in the green lines. This was good because my definition of a buyable flag requires a channel break down from the flag pole. The next thing it did on Friday was climb back into the flag pole channel and go to a new high for the move. The new high negated the flag pole channel break that occurred earlier so now prices were still in the flagpole and stayed there for most of the rest of the day.
The new high also caused me to adjust the flag pole bottom downward to include Friday morning's low. So now you see that the flag pole channel had not been broken on Friday, so a flag could not form.
Today is a different story. The new flag pole channel, outlined in red, was decisively broken this morning and gives me hope that a flag could form here. A buy today is unlikely because the bottom of the flag pole should be tested before a flag forms and that will take some time. A two day flag is entirely possible for today and tomorrow, giving the possibility of a buy for tomorrow afternoon.
Another possibility for tomorrow is a drop to new lows. This would not be a flag, but would open up other buying opportunities. Stay tuned.
Happy trading.
