【Trading is like water】:

When you are high, I will retreat, never dumb buying at high positions;
When you are low, I will surge in, never miss the opportunity;
When you move, I will follow, never reverse the trend;
When you are calm, I will be patient, never vacillate;
When you are hot, I will boil, never leave easily;
When you are cold, I will solidify, never trade frequently.
