Yeah, for me there were opposing forces at work on that chart, and the price action had not yet shown which side would win.
So it was unresolved, and made the outcome clouded or questionable (for me) at the cut off point.
No doubt some supply had arrived in mid September, which pushed price down. And usually if this is an important supply event, price would either quickly break lower (like a pump and dump), or double top (with maybe a little sideways action following it, to finish unloading, and to set fresh shorts). But neither of those scenarios really happened. Instead price put in only a shallow pullback and then attempted to consolidate (or absorb) the supply being drawn out. So for me it still could have gone each way, and I would have waited for price to break one way or the other.
You had me wondering if it was a trick chart, and if the next bar would be a widespread response by the market, where an unexpected announcement causes either a large scramble for stock, or a massive sell off ..... both of which happens from time to time.
