Trendlines can be awkward at the best of times, originally I had a shorter daily, when that was breached and became invalidated I panned out and had to move further back to March as you discovered. What I have noticed is, trendlines tend to hold at the third attempt, traders will shy away, and as we have a round number and a 50% retrace converging around 4th to 9th December, this will be a third attempt on this trendline, for me, signs of a stronghold against the sellers.
Of course it may hit the trendline earlier, shy away and then retest it for a fourth time, but area indicated has my attention.
