Is there any way to receive alerts when this trade setup occurs on any cryptocurrency or forex pair, etc (is a very specific setup, I dont think is a normal macd crossover etc...
The CoinMarketCap would keep you updated on every crypto market price whether on increase or decrease of prices which you can use to setup your trades formations.
If you want think of how to get informed of making good trading strategy, I doubt if there's a reliable one unless you'd dive and discover your own strategy.
If you also think the above trading experts as said is a reliable for you, then you can always follow them on their media handles which I believe they'd have trading streaming channels to update their followers. But then, I'll just say you should be careful of those claiming trading experts in the media.
