A trader warns against risking money based on others' claims. Instead, test any strategy yourself on a large enough sample to rule out luck, then commit real capital only after you've verified it works with data.
For any trader that's not profitable yet, this is best advice. Find something that proves you that it works by data. Most people trust other people's words and they put their money on trust. Is it really a good idea? Not really. Even if I'm saying trade this because it works, you shouldn't trust me. You should test it. If it works across large enough sample that variance can lie to you, you can put your money on it.
