1) Vertex and bottom–30 and 70 are usually oversold and overbought signals.

2) Deviation-When market conditions hit a new high (new low) but RSI did not hit a new high, this usually indicates that the market will reverse.

3) Support level and resistance level-RSI can show support level and resistance level, and sometimes it can reflect support level and resistance level more clearly than the price chart.

4) Price trend patterns-Compared with the price chart, the price trend patterns such as double top and head-shoulder top are clearer on RSI.

5) U-turn-when the RSI breaks through (exceeding the previous high or low), it may mean that the price will suddenly change, which is the same as other indicators. RSI needs to be used in conjunction with other indicators, and cannot generate a signal alone. The confirmation of price is the key to determine the entry price.

The variation range of RSI is 0- 100, and the strength index values are generally distributed in 20-80.

80- 100 sells very strongly.

Top 50-80 buyers

20-50 weak wait and see

0-20 Very weak buy

Here, "extremely strong", "strong", "weak" and "extremely weak" are only relative analytical concepts.
