What is Contra Trading?

Contra represents a trading method in which the investor refrains from taking possession of the stocks bought or delivering the stocks sold. The investor buys the stocks without any cash upfront and sells them after a period of time. The investor then makes arrangements to settle any outstanding differences, which may result in either profits or losses.

How can the Contra Trading feature of a Cash Boost account be utilized to improve the efficiency of capital utilization?

Imagine Tom spots a good trading opportunity but his current funds will only be available 3 days later, he can use his Cash Boost Account's limit to buy the stock first. Scenario 1 - Funds delayed 3 days later, due to unforeseen circumstances, Tom's funds are still not available. Thankfully, the stock price increased from when he bought them. Tom sells away the stock and pockets the difference as profit, without even having to settle the outstanding buy trade. This is also known as Contra Gain. Scenario 2 - Settling the buy trade 3 days later, Tom decides to keep the stock for the long term. He transfers his funds to his Cash Boost Account to settle the trade.

How does Contra Trading work in a Cash Boost account?

The Cash Boost Account comes with a default credit limit. To start, simply place a buy order. Once the buy trade is done, it will become an Unsettled Buy (Outstanding Buy).

For SG and HK market, you will have up to 5 Trading Days (Contra Period) to perform a corresponding sell trade (Contra Sell) before force-selling date.

For US market, you will have up to 4 Trading Days (Contra Period) to perform a corresponding sell trade (Contra Sell) before force-selling date.

After the Sell trade is done, a Contra is formed. You will have to settle the difference between your buying price and selling price. If this difference is positive, known as "Contra Gain", you get to keep the profits. If the difference is negative, known as "Contra Loss", you will have to make payment to settle it. Assume Tom bought 100 shares at USD 10 a share and subsequently performed a Contra Sell, 3 Trading Days later:

Scenario 1 - Contra Gain

Scenario 2 - Contra Loss

Purchase Price

​USD 10

USD 10​

​Contra Sell Price

​USD 15

​USD 8

Difference (Price difference × Quantity)

​(USD 15 - USD 10) × 100 = USD 500

​(USD 8 - USD 10) × 100 = USD -200

Trading-related fees are not factored in the above examples. Scenario 1 - Tom netted a Contra Gain of USD 500. This amount will be deposited into his Cash Boost Account.

Scenario 2 - Tom incurred a Contra Loss of USD 200. Tom will need to make payment into his Cash Boost Account as soon as possible to avoid interest.
