The ancients said:
Do not rejoice excessively in victory, nor despair excessively in defeat!
Those who have thunder in their hearts and a calm lake on their faces!
May they be honored as generals!
Trading should be done this way!
In the face of a surge, do not chase recklessly!
Take profits in batches, do not be greedy!
In the face of a plunge, do not recklessly add to your position!
Keep your heart as still as water, do not disrupt your own formation!
