I'm definitely not an expert - far from it, I post here so that someone with more knowledge on TA can come and correct anything I'm thinking or saying as I am just trying to learn.

I don't really read too much into it to be honest, the market can change rapidly particularly when fear of either losing or missing out after other traders push the price of a security in a particular direction. I did perceive a lack of buyers available for sellers to sell into, but sellers were also not falling over each other to sell which would have resulted in rapidly falling competing offers and eventually the price even lower.

In fact sellers were so demotivated that it only took a single purchaser buying ~600 shares @ close to retain the support of the flag pattern.

You could say that you cannot rely on data affected by a single trader but in reality that single trade represented the aggregate opinion of the market. Support ended up winning out over sellers.

Does that answer your question? Do you have your own opinions?
