每日只TRADE 3次.

請問每日只TRADE 3次甚樣寫?

你這個問題等同於 Intraday (Buy/Short) 出現的次數

可以利用計算Buy , Short 出現的次數來得知

Example: (assume already removed redundant Buy signal)

1. dn = DateNum();
   
2. Buy_signal_sum = SumSince(dn!=Ref(dn,-1),Buy);
   
3. 
   
4. // Buy signal removed if Sum > 3
   
5. Buy = Buy and (Buy_signal_sum <=3);

複製代碼
