I've been in an out of LABU over the years. I rode it up recently to the upper trend line. I now see a pullback complete and a chance we are breaking out of a bull flag higher. Stop anywhere below the flag (dotted red lines) should break above the upper trend line and move higher. IMHO
RSI and MACD are showing a negative slope with price peaking to new highs, which should indicate an imminent pullback. If the MACD crosses over positively after the pullback, that is likely to be a good partial buying opportunity.
