Six iron rules of the currency circle:
1. Buy with patience, sell with determination, and hold on with confidence.
2. Buy when the price rises and falls slightly; sell when the price falls and rises slightly.
3. Buy in batches, and you won’t lose money; buy all at once, and you will lose more money.
4. If you hold the support level for a long time, you will lose it; if you attack the resistance level for a long time, you will break it.
5. Both shorts and longs can make money, but only the greedy ones can’t.
6. Eat until you are 80% full, and make 80% of the profit from trading.
