Notes on the GBP/USD Breakout Strategy for Wednesday/Thursday:
Last night's breakout was completed at 07:20 GMT Wednesday, at which point the down-move reversed, later breaking out of its descending channel, and establishing a new, ascending channel. This new ascending channel, bounded by Lines 63 and 64 on the current chart, is still intact.
After the reversal of last night's breakout, the GU went on to test 1.6500 before pulling back into a narrow, well-defined range during the current Overnight Period (marked by the right-hand pair of green, vertical lines). The narrow range from HIGH to LOW in the current Period makes a breakout look very likely tonight --- however, at this time, direction is very uncertain.
A newer, shorter, narrower, descending channel has formed since about the start of the current Overnight Period. This newer channel is marked by Lines 75 and 76. Presently, the GU is inside two channels (the larger ascending channel, and the smaller descending channel), but it won't be able to stay there for long. It will be interesting to see which channel the GU chooses to respect.
On this chart, I have marked some potential support levels which a downside breakout would have to contend with. These are marked by Lines 74, 68, and 69. Line 74 is intended to flag the congestion area between 1.6390 and 1.6410 encountered last night, before the breakout, and indicated by the boxed-in area.
Line 67 marks the Day's High, which may or may not be significant resistance (in the event of a breakout to the upside tonight). A strong upside breakout could blow right through this resistance level, but it's impossible to predict that.
I will post another chart, and give specific prices shortly after 04:00 GMT.
