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 a good strategy because of this.
I learned trading indicators are not accurate and in most cases, there are no known trading indicators so if you are looking for that you better start developing your trading skills because that's the only way to have a workable trading formula for your trading portfolio
