The technical index of intraday reverse operation, also known as contrarian operation index, is the CDP value of the next trading day calculated according to the opening price, highest price, lowest price and closing price of the previous trading day:

The highest price (AH), the second highest price (NH), the middle value (CDP), the second lowest price (NL) and the lowest price (al).

The general operating rules are:

1, when the opening price is higher than CDP, it belongs to a strong market; When the opening price is lower than CDP, it is a weak market.

2. When the price goes up to NH consolidation, wait and see first, because the price is likely to fall back;

When the price breaks through NH, it often breaks through AH.

3. When the price goes down to NL consolidation, go out and wait and see first, because the price is likely to be adjusted back; When the price exceeds NL, AL is often broken down.

By the way: CDP indicator is mainly used for intraday speculation of futures, because stocks are T+ 1 trading, so it is not applicable.
