Everyone has their own approach, their own habits, but what I realized for myself is that it is important to create a list of rules that you will never break under any circumstances.
Not a huge list, up to 10 rules, but once you start sticking to it your trading results noticeably improve. So everyone looks for their own approach but I definitely would never buy any strategy for money.
To me, they all bounces back to discipline and whenever a trader is disciplined enough they can or could abide to some specific strategies to follow and it doesn't require much just as you said, 5-10 is okay for a smart trader who must make profits. Sometimes the amount isn't the basics things or becoming too smart is not the utmost thing but how long they could remain in trading count mostly that is why some many traders who claims to be Smart traders today are no place to be found in the market because they are being swiped away by the market volatility. Although some of them are solely interested in shitcoin which they thought it's the fastest way to make profits from the market without knowing that the market isn't for the weak minded. Realistically, basing on specific strategies and key into them helps alot and that would make them remain on track.
