In my honest opinion, forex strategies don't usually/always work. You elaborate a strategy for a particular group of assets and for a certain time lapse (for example for a week, month, half a year and for stocks/cryptos). You know that the market is instable and once your strategy works well, then there will be a moment when it won't work at all. I guess that it's quite useful permanently think about various strategies and test them in demo. It will not only save your accumulations but also will give you more flexibility and experience. Just try this scheme one day and you'll understand that it can really work.
