This type of挂单交易 will not be squeezed. The only concern is encountering a one-sided downward market.

#BR Just finished a 16-point rank, principal 2550, I've recently been using the pending order trading method, worn down 6u, remaining 2444u
Recently, I've been grinding BR, the first order was a pending buy at 8:01, pending 0.04777, sold at the same price for 13 times.
I have been grinding on the exchange, not in the wallet. I heard that grinding in the wallet can refund half the fees, but I didn't go, finding it troublesome.
