The only thing that can change is the key features of exchange and the introduction of new features such as the now known stop lose features on some exchanges it was not there in the time past.
But nothing much has changed in trading it still has the old traditional way of doing it.
Same rules are with trading even on Forex and stock market, we all have a general indicators to be use in trading so I believe there’s no such Millennial guide since the old indicators are still the basis for trading analysis. When it comes to strategy, I believe it will depend on you and you should develop your own strategy. First learn the basic of trading, and know the importance of each indicators, you can have good strategy because of this.
That’s correct same indicators works on every trading site and on any market, the big difference is the execution. Trading is not easy, this is time consuming since you have to analyze properly but if you do it correctly, its more rewarding compare to any job. Well, the risk is high as well and that’s why its more profitable, if you can’t handle such risk then better to just hold and stay a not active trader or the so called hodler.
