AMBA — The relevance of RSI can be overstated after a trend has extended. It is comprised of only so many preceding periods (14 is a common default) and so that’s all it reflects. If most of the days during that period of time descended at a consistent pace, then RSI won’t ever get ahead of itself, i.e. “oversold.” So, avoiding oversold becomes irrelevant.

RSI reflects buying and selling pressure. MACD price momentum would be more insightful at this stage. Also, note that volume is relatively low during this recent part of the decline — so, apart from the potential for a sudden brief bounce, bottoming is not likely soon.

WMT — I don’t see another session’s low that was being retested in the context of a Double Bottom, so it doesn’t look bullish to me.

WMT – I don’t see a Double Bottom today, since reactions up haven’t done anything complex in the interim. Were you referring to today’s low retesting a prior session’s low?

TRTC — I don’t see anything new, just new fluctuation within the pre-existing range. Back above .135 could start to suggest otherwise

SMG — I like that the recent rally stopped pessimistically short of actually touching the prior highs, but has consolidated there anyway. Still, volume could be better. So long as 64 holds as support, extending above 67 on expanding volume would be bullish.
