1, two-way pending orders, three minutes before the non-agricultural data came out, silver put up a high order of about 100- 120, and a low empty order about 100- 120 lower than the current price, with 50 stops and 80 stops. After a transaction, delete another unfinished transaction.
2. Three minutes before the data comes out, you can hang multiple orders at 30 points above the current price, hang empty orders at 30 points below, and stop losses by 30 points. After an order is closed, you can delete another order that is not closed. This operation is more radical.
