Why Hasn’t My Withdrawal Arrived?

1. I’ve made a withdrawal from LBank to another exchange/wallet, but I haven’t received my funds yet. Why?

Transferring funds from your bank account to another exchange or wallet involves three steps:
  • Withdrawal request on LBank
  • Blockchain network confirmation
  • Deposit on the corresponding platform
Normally, a TxID (Transaction ID) will be generated within 30-60 minutes, indicating that LBank has successfully broadcasted the withdrawal transaction.

However, it might still take some time for that particular transaction to be confirmed and even longer for the funds to be finally credited into the destination wallet. The amount of required “network confirmations” varies for different blockchains.

For example:
  • A decides to withdraw 2 BTC from LBank to her personal wallet. After she confirms the request, she needs to wait until LBank creates and broadcasts the transaction.
  • As soon as the transaction is created, A will be able to see the TxID (Transaction ID) on her LBank wallet page. At this point, the transaction will be pending (unconfirmed) and the 2 BTC will be frozen temporarily.
  • If all goes well, the transaction will be confirmed by the network, and A will receive the BTC in her personal wallet after 2 network confirmations.
  • In this example, she had to wait for 2 network confirmations until the deposit showed up in her wallet, but the required amount of confirmations varies depending on the wallet or exchange.

Due to possible network congestion, there might be a significant delay in processing your transaction. You may use the transaction ID (TxID) to look up the status of the transfer of your assets by using a blockchain explorer.

  • If the blockchain explorer shows that the transaction is unconfirmed, please wait for the confirmation process to be completed. This varies depending on the blockchain network.
  • If the blockchain explorer shows that the transaction is already confirmed, it means that your funds have been sent out successfully and we are unable to provide any further assistance on this matter. You will need to contact the owner/support team of the destination address to seek further help.
  • If the TxID has not been generated 6 hours after clicking the confirmation button from the e-mail message, please contact our Customer Support for assistance and attach the withdrawal history screenshot of the relevant transaction. Please make sure you have provided the above-detailed information so the Customer Service agent can assist you promptly.

2. How do I check the transaction status on the blockchain?

Log in to your LBank account and click [Wallet] [Spot] [Transaction History] to view your cryptocurrency withdrawal record.

How to understand the definition of Maker Taker

What is Maker?

Maker is an order placed at a price you specify (below the market price when placing a pending order or higher than the market price when placing a pending order). Your order is filled. Such an action is called Maker.

What is Taker?

Take order refers to the order at the price you specified (there is an overlap with the order in the market depth list). When you place an order, you immediately trade with other orders in the depth list. You actively trade with the order in the depth list. This behavior is called Taker.

Differences Between Spot Trading and Futures Trading

This section outlines key differences between Spot trading and Futures trading, and introduces basic concepts to help you read deeper into futures contract.

In a futures market, prices on the exchange are not ‘settled’ instantly, unlike in a traditional spot market. Instead, two counterparties will make a trade on the contract, with settlement on a future date (when the position is liquidated).

Important note: Due to how the futures market calculates unrealized profit and loss, a futures market does not allow traders to directly buy or sell the commodity; instead, they are buying a contract representation of the commodity, which will be settled in the future.

There are further differences between a perpetual futures market and a traditional futures market.

To open a new trade in a futures exchange, there will be margin checks against collateral. There are two types of margin:
  • Initial Margin: In order to open a new position, your collateral needs to be greater than the Initial Margin. 
  • Maintenance Margin: If your collateral + unrealized profit and loss fall below your maintenance margin, you will be auto liquidated. This results in penalties and additional fees. You can liquidate yourself before this point to avoid being auto liquidated.
Due to leverage, it is possible to hedge out spot or holding risk with relatively small capital outlays in the futures market. For example, if you are holding 1000 USDT worth of BTC, you can deposit a much smaller (50 USDT) collateral into the futures market, and short 1000 USDT of BTC to fully hedge out the positional risk.

Note that futures prices are different from spot market prices, because of carrying costs and carrying return. Like many futures markets, LBank uses a system to encourage the futures market to converge to the ‘mark price’ via funding rates. While this will encourage long-term convergence of prices between spot and futures for the BTC/USDT contract, in the short term there may be periods of relatively large price differences.

The premier futures market, Chicago Mercantile Exchange Group (CME Group), provides a traditional futures contract. But modern exchanges are moving toward the perpetual contract model.
