That also mean that even though how successful the strategy to the person who said it still the person who copy it cannot assure to replicate the result since it will all matter the level of patience and how consistent the people are to do such strategy what they call. Also we cannot fully rely on this since for sure every phase have different result and might we cannot use this always.
So its good for every to develop different methods so that they can be consistent on their own trades without relying on someones ideas.
And that's why, if one could have the ability to analyze and be able to get methods from other people, it would probably yield better results for him. Patience and consistency also play a role in trying every method or strategy because we don't know which will work for us.
This will vary only on persons dedications if they could learn something from people who's experience doing some good trades since if they just follow them without absorbing the knowledge or information they get from multiple experience traders they didn't get anything from them. So consistency is always the main key to learn from trading since if he could apply what other and his experience for sure he will became more better trader and can able generate profits for that.
