Amalgamation is a way of calculating commission charges. A collective commission is charged against the total value of the day's trades for the same stock, instead of separate commission for each trade executed. Do note that amalgamation is only available for SGX, ASX, Bursa, HKEx and HK-Shanghai/Shenzhen Stock Connect, SET trades if the following conditions are met:

- Trades must be done through the same trading channel (i.e. online or via broker)
- Trades must be of the same action (i.e. buy or sell)
- Trades must be done on the same trading day
- Trades must be of the same security
- Trades must be of the same payment mode (e.g. Cash, CPF, SRS) and settlement currency

There is no amalgamation of trades for US, TSX and LSE trades,
