If you're looking to benefit from each possible price movement, you have to monitor the markets basically non stop. I quite often end up staying at home for days without even going outside, just to benefit from this market action. I must however note that I am of course not staring at my screen if the market happens to move extremely slow. I can only justify investing full days of my time into trading if there is enough volatility. Aside from that, gambling is never a good combination with anything. Gambling is a losing game, seriously.
4 hr time frame monitoring is good practise although not the method i prefer.
but the combination u feel good then good!
about price movement (Price action -PA), no need non stop, if u do short trading, just use the time to read chart.
However, bitcoin trading and forex/CFD trading is different, but PA things and chart reading, is the same.
