One more selloff before a real reversal?

We had a daily candle close below the March trend line a few days ago, with buyers supporting the 320 levels on the quick recovery the next day (Since beginning of September these levels were support as well).
Resistance on the 100Day MA and support on the 20Day MA right now.
March trend line acting as support again, no bounce off it yet. If we break below March trend line again or the 100Day MA, something like this may play out before we see a real recovery.
