If the market is still bullish the RSI should probably hold above 40.Next Support, and the Bullish Outlook:- A hold above 24.50 could be a sign that TAN is still bullish, and thus maintains a bullish outlook with upside above the 26.70 high. - We should limit the bullish outlook to the 32-32.80 area, which is a key support/resistance area. - However, if price dips below 24.50, it could gravitate towards the next key support around 22-23. On the weekly chart, we can see that this was another common resistance that might turn into support if the market is still bullish.- If price does go down to 22, I would cut back on the bullish outlook to something like 28, just under the 200-week SMA.
