Bottom panel is a juiced up RSI (yellow) with a fast and slow trigger line.
So market is overbought but someone continues to buy as we push back into Wednesday's range. If you even begin to think this is normal retail buying look at where price is, over 4 atrs above the 20 period EMA. Note the Thursday morning CTA trigger sell off also was 4 atrs out, only to the down side. So the whales are making moves.
Edit- the letters on the chart are generated by the Lizard Trader zerolag indicator (pannel 3). Momentum, Key retracement secondary Retracement.
