Mt. Gox

The most widely used bitcoin currency exchange market. Bitcoins are bought on using funds from the trader's MTGUSD balance with Mt. Gox and when bitcoins are the funds from the proceeds are added to the trader's MTGUSD account with Mt. Gox.

Trades on Mt. Gox's execute from balances on deposit with the exchange which in turn makes trading on the market instantaneous, compared to some other Bitcoin markets where a subsequent settlement occurs manually between the trading partners.

Trading

Buying

A buy order is executed partially or in full when the price bid can be matched against a sell order that is at or below the bid amount.

Selling

A sell order is executed partially or in full when the price asked can be matched against a buy order that is at or above the ask amount.

Dark Pool

A dark pool allows large quantities to be sold without the orders being visible. This helps to lessen the price moves that would likely result when the price and size of a large order is known.

Dark Pool Only Orders

Can be filled only by other dark pool orders or a single normal order that is larger than the dark pool order. This means that if there is a single normal order that would fill the dark pool order both will be filled.

Dark Pool + Normal Orders

Can be filled either partially from the normal orders or the dark pool.

Fees

Mt. Gox subtracts a 0.65% trading fee from each party of successful trades made through the market. The fee is drawn from the amount received as the result of the trade.

BTC

Bitcoins may be withdrawn at no charge.

There have been sporadic reports where withdrawing the entire bitcoin balance results in an error message. This could the be the result of a possible error where the amount available for withdrawal gets miscalculated due to a rounding error. In at least one instance, a subsequent attempt to withdraw all but the last 1 BTC completed successfully.

LRUSD

There are two fees incurred when withdrawing LRUSD. Mt. Gox themselves subtracts 1% of the transfer amount as a fee before transferring away. Liberty Reserve then subtracts as a transfer fee 1% from the amount they've received.

For example, to withdraw $100 LRUSD, Mt. Gox will send $99 ($100 less a 1% fee) Liberty Reserve will subtract $0.99 ($99 less a 1% fee) leaving a net amount at Liberty Received of $98.01.
