I dont track a whole sector but individual stocks. No predefined system but more of watching graphs. Stocks after a fall when they start rising again then they are candidates. If it is from a support then better.
Stocks can rise quickly after a fall single bottom. BPCL chart posted earlier in this thread.
After a fall, short rise it can fall again. Making a double bottom. Like reliance at 1310 also yes bank carbon copy. chart posted earlier in this thread.
Sometimes after a fall stocks can consolidate for a while at a support like ujjivan. chart posted earlier in this thread.
In case of multiple bottoms. The second/third bottom can be higher or lower than first bottom. I just be aware of all these scenarios and act accordingly. If things not working as expected leave it alone.
Exact inverse for shorting.
Can you elucidate, how do you implement this sector rotation strategy?
