Given it’s so important, you might be wondering what affects the spread? That would be the market’s liquidity, which is simply the ease with which it can be traded in the market. Typically, the higher the current volume of trades on a market, the narrower the spread.

Spread Betting

When spread betting, the only cost for entering and exiting a trade is the spread.

For shares, the spread is made up of two components: market spread and Spreadex spread. Market spread is the difference between the bid and ask in the underlying market and is mainly driven by liquidity. The Spreadex spread is essentially a commission charge. Let’s say ABC corp trades in the underlying market at 98 – 102. It may then be offered on the Spreadex platform at 97 – 103. The total spread here is 6 points, of which 4 is market spread and 2 is Spreadex spread. If you see the spread changing intraday on the platform, that will be because the market spread is changing.

For non-shares markets such as stock indices, commodities and FX, the spread is essentially chosen by Spreadex whilst factoring in market spread. Sometimes this can lead to Spreadex offering an even tighter spread than the market! A good example of this is the Dax where Spreadex offers spreads as tight as 1.4pts. Please note that these spreads can be variable and so during times of lower liquidity in the underlying market, the spread may widen.

CFD Trading

When CFD trading on shares, there are two costs for entering and exiting a trade: spread and commission. This time spread refers to market spread only. In addition to market spread, you will pay commission which will be applied as a cash debit on the account. You might be thinking is it cheaper to trade CFDs or spread bet? The fees are the same and the only difference is how they’re charged. The commission charge with CFDs should equate to the Spreadex spread with spread bets.

For non-shares markets such as stock indices, commodities and FX, the only charge for entering and exiting a position is the spread. Like with spread betting, no other commission charges will be debited from your account.

Financing Costs

Funding Charges for a Shares Rolling Position

If you hold a rolling position through the close of the relevant exchange (16:30 for UK Shares), the trade will be kept open for the following day's trading and a funding adjustment will be applied to your account. Funding is essentially the cost of using leverage – the fact you only have to put down a fraction of the full trade value.

The funding charge is based on the Adjusted ARR + a Spreadex charge. More information on adjusted ARRs can be found but they are essentially relevant interest rates. For FTSE 350 stocks, we use the 30-day Sonia interest rate and the Spreadex charge is 3%. Therefore, if the Adjusted ARR was 0.5%, the total daily funding charge for a long position held overnight would be (0.5% + 3%) / 365 = 0.0096% of the position’s value.

Let’s say you hold a long (buy) position in Barclays of £50 and it closes the day at 200p, your funding charge for the night would be (50x200) x 0.0096% = £0.96.

So what happens if you are short? Well, the 3% charge is subtracted from the Adjusted ARR rate. Unlike long positions, the total funding adjustment on short positions can result in either a positive or negative funding adjustment. If the Adjusted ARR is greater than the 3% charge, the funding adjustment will be positive and credited to your account. If the Adjusted ARR is less than the 3% charge, the funding adjustment will be negative and debited from your account.

Now let’s say you hold a short position in Barclays of £50 and it closes the day at 200p. If the Adjusted ARR was 5%, you would be credited funding for the night of (50 x 200) x ((5% - 3%) / 365) = £0.55.

Please note that funding is trebled on a Friday afternoon to account for holding a trade over the weekend and bank holidays will be similarly charged.

The Cost of Rolling a Futures Trade

Rolling a Futures Trade

There is no charge for holding a future overnight, instead financing fees are factored into the price. If you would like to keep your exposure past the expiry of the relevant instrument, then you can set the position to roll automatically via your trade preferences. What does it mean to roll your position? Your position will be closed in the expiring contract and new position will be opened in the next available future of the relevant market.

The cost of rolling a futures trade is the spread. For non-shares markets like stock indices, commodities and FX, your position in the expiring contract will be closed at the sell price (bid) and opened at the buy price (ask) of the next available future. Remember that for shares, the spread is made up of two components: market spread and Spreadex spread. The good news is that when rolling a shares future, the only cost is the Spreadex spread – i.e., no market spread is incurred.

Short Borrow

So, to sell shares you don’t own you must borrow them. Borrowing shares incurs a daily fee known as a short borrow charge. For stocks that are borrowable in the underlying market, the borrowing charge with Spreadex is the rate in the underlying market. If the stock isn't available for borrowing in the underlying market, we may still let you place a bet. However, this borrowing cost is going to be higher - typically around 10% of the stock value per year.

If you’d like to know the applicable short borrow charge before opening a short on a stock, get in touch with our dealing desk who can advise on the applicable rate. Do note that these charges can change depending on the availability of borrow in the underlying market.
