The RSI- Realtive Strength Indicator- is in the top zone- above the 70 mark and that is at the top or in the power zone. As it approaches the 50 line and goes to the 70 level- that is a good place to buy. When a stock is moving and stays above the 70 mark- the strength remains high.
For scouting to buy purposes, you want to find the RSI hooking upward from the bottom headed to the 50 mark and hopefully to the 70 and up.
MOre information than you may have wanted-LOL- but there it is.
I always hope to see the Wm% and the RSI hooking upwards together- they are good together for possible moves up.
