The internal market is an active selling order

The external market is an active buying order

However, at a point in time, not all submitted orders can be filled

p>

If the transaction cannot be completed, it will show an inconsistent situation.

It’s normal. For example, if you are long 10 lots, but no transaction is completed, the information of your 10 lots before canceling the order will be reflected in the external disk data. After you cancel the order, your 10 lots will be reflected from the outside data. The external disk data disappeared.

The data here is inaccurate. Many times there are orders that need to be withdrawn.
