Depends on strategy that you are using, I'm just too focus on very few indicators because I believe on their effectiveness and they are working with me. I just look on Price trend, Volume, Rsi, Fibonacci, MA and MACD most of the time but if you're dealing on some project that is highly volatile, I don't think indicators will work, I just used my luck every time I buy those so called shitcoins. You must be more flexible because this market offers different options everyday.
with the more indicators used, it will increase our consideration for the transaction, and I think that is not very good. therefore we use simple indicators that suit our system and most importantly we must be aware that the indicators are not all correct, so we remain careful.
But I don't think it is necessary for us to take a look at all of them. RSI, volume, and market trend (candlestick reading) could be enough to have some insights into a possible trend to come. What really matters in trading is to know how to use these tools and most important is to control our emotions.
Ain't no wrong having them all as you think that it could help and enhance your chances and to understand that it was your ideal choice, and I have my own also. And as I was good enough with the results of my trading without having these all trading tools, I don't think that I need to look at them.
