Namvo,

thanks for your question.

if you are asking, was there a confirmation that the bottom is in ? And when was that?

IMHO, The low on the 13th December needed to be re-tested and confirmed after the 4.9 high the day after.

The two candles for mine that "confirmed" the bottom were on the 22/12 which was a re-test of the pivot point low of the 13th and the candle on the 27th.

Even though the trading on the 13th fell to the 150dma it needed further trading (price action) to confirm this was a pivot point / bottom.

Certainly allowed plenty of time for a low risk entry. Certainly looking bullish and interesting to see what transpires in coming weeks.
