So here's the list:
MACD = Buy and Sell Signals
RSI= shows when price is overbought and oversold
Bollinger Bands= volatility levels
9EMA= Short term trends
21EMA= Entry and Exit points
50 EMA= helpful for Stop loss placement
200 EMA= Long-term trend
VWAP= Intraday Breakouts
ADX= strength of the trend
You made a list of indicators without giving more details about what they do, how to use it, when to use it and the implications. For your information, in that list you compiled, there are leading indicators and lagging indicators, using lagging indicators to confirm your trade without lagging indicators to comfirm your trade makes you lagger person or trader. You will not make anything and if you managed to make anyone, I will say you were lucky with it. The ones you mentioned are are popular indicators on most exchanges and yet many don't know how to use them together.
For indicators, we have the lagging and the leading, they all have their own merit and demerit, when to use them and when not to use them. The leading ones for example helps you comfirm a trend or direction of your trade before it happen while the lagging will only work after a trend has been confirmed. So, you see that when you choose lagging to comfirm trades, you will always be behind other trades, they always see dangers before you and will quickly exit and take profit before you in the market.
The only leading indicator I know from your list is the RSI and the rest of them are lagging indicators. You don't need all of them to be an expertise in trading though.
Key note: Just because it is listed does mean you should use it all. All have their purpose and you can just use what resonates with your strategy whether you are a short-term or swing trader. You can just use EMA for signals and confirm it with buy/sell of MACD. The most important is you have a sample data that you're strategy is working and backtested.
200MA is not suitable for hourly or daily candle of a newly launched pair coins on exchange, it takes weeks of candles and monthly before they pop up. However, I think 21, 50 EMA, Bollinger Band, Macd and RSI are enough to enjoy trading except for premium indicators that you may want to add for professionalism, but they are not necessary to have them in your chart.
