What the RSI indicator actually tells you (and what it doesn't)
RSI measures how stretched a recent move is on a 0 to 100 scale. It is useful for timing, useless for prediction, and misread by most beginners.
Technical analysis
Supportneeche ka sahara, jahan buyers aa jaate hain
A price level where a falling stock has repeatedly stopped and bounced because buyers step in, acting like a floor until it breaks.
Support is a price zone where a falling stock has found buyers before and turned back up. It might be a previous low, a round number, a rising moving average, or a level where heavy volume traded earlier. If SBI has bounced from around ₹760 three times over several months, ₹760 is support. Traders buy near support with a stop loss just below it, so the loss is small if the level fails, and they treat a decisive close below support as a sign that the trend may have changed. Once broken, support often becomes resistance, as trapped buyers sell on the way back up. Support is an area rather than an exact price, and each test weakens it as buyers there get used up. Do not assume a level will hold because it held before; plan for both outcomes.
