As soultrain highlighted in his RBA snag, the blue touch paper was lit at the w/end. Volumes ticked up noticeably right off the bat across the currency all through Monday's local session & the subsequent London/European follow through, continuing into Tuesday.
Yeah, you've obviously identified & applied it correctly in this instance.
It alerted entries via the 5m at c4170 local time, c4200 towards the end of their shift & c4250 an hour or so into Europe.
Even at the 4200 entry you still had a thick chunk of the day's range left in play affording you more than acceptable odds considering the logical stop protection available, especially if it was an intraday bet.
Sterling v/s Oz carries much heavier weight via the average days range than Euro, so if you're intending betting an Oz influenced story next time, look see if it's displaying similar technical behavior (via your background hook template) on that pair as you'll receive potentially more bang for your buck!
Nice bet though!
I would be very surprised if it took her more than a few lines of text to explain the structural make-up of the template.
If you can identify obvious bias/price pressure/trend development then it's covered.
Don't overthink it.
It's either exhibiting a bias (via your preferred background chart) or it isn't.
It should take you no more than 10-15 seconds to identify.
Any longer & you're forcing it!!
