Most foreign exchange banks have developed proprietary systems for their customers to trade FX online. Some banks have developed their systems entirely in-house, whereas others have made use of external technology such as AVT and Cognotec.

Most systems provide automated prices that are tradable up to a certain limit, dependent on currency or currency pair. Limits vary from bank to bank, but are typically between USD 2 million and USD 10 million for major spot currency pairs. Limits are typically much higher for swaps, particularly for short dates.
