Some technical indicators(BB, RSI, KDJ, PSY)seem to have a common formula. I just use the simplest way to understand, when the moving average reaches these technical indicatorshigh area is overbought (sell signal)AndOversold at the bottom (buy signal).。
When a technical indicator gives a buy or sell signal, we may not be very certain about its current trend (some technical indicators may be slower, such as MACD). In this case, we can observe several different technical indicators to determine the current trend. When multiple different technical indicators point in the same direction, we can be more certain about the current trend of the stock.

This time I chose a popular stock. $Tesla (TSLA.US)$ 
The following chart has two.Red circles.What can you observe?
1. MACD enters a death cross, with a decrease in trading volume.
2. BB stock price exceeds the high part of the Bollinger Band.
3. When KDJ exceeds 80.
4. RSI exceeds 70.
5. PSY exceeds 80.
These are all bearish signals. When several technical indicators simultaneously show bearish signals, you can notice that after these signals appear, the stock price opens...
