Strategy system setup very important for successful traders

Seeking expert guidance, what is the difference between left-hand trading and right-hand trading?

Tell me how hard you have worked to make money in trading?

Why can you see the general direction right, but make a bad point in the transaction, and lose money instead?

Why do really successful traders never share their methods or strategies?

Some people say: One point of trading depends on technology, nine points depends on emotion, what do you think?

The trading mentality is always demonized. It is true that the mentality will affect the order, but it is too exaggerated. Shouldn’t it be that one has strong technology to have a stable mentality?
