Waiting for confirmation is probably the smart thing to do!
On the other hand:
1. If you believe in the scenario, buy now or at a possible e wave (about the same price I would expect, so you could buy now...) with SL above wave a for the best entry.
2. If you believe in a scenario, try to buy at a possible d wave with tight SL below support for the best entry.
The black double sided arrows are attempts at thrust measurement.
The scenario has potential for a very nice R/R, even with confirmation. The scenario is less favourable but maybe more likely... We'll see...
Nothing's fixed, adjustments can and probably need to be made depending on actual PA!
