Execution and pricing technology

Our technology is engineered for speed, stability and better prices  giving you the edge in a competitive environment.

How we provide fast, reliable execution

Our systems are built to cope with a huge number of trades very quickly:

  • 6,930,497 orders accepted per month (12 months to October 2015)

And our robust platforms are engineered to cope with large volumes of traffic:

  • 39,000 unique daily web users (12 months to October 2015)
  • 37,000 unique daily mobile users (12 months to October 2015

Two new ways to trade

We now offer you even more control over your order execution, with partial fills and points through current. These new features are available on the trading platform and the latest version of the IG mobile trading app. For full terms see our customer agreement page.

Partial fills

We now offer clients partial fills on their online trades. If you are a client who trades in large size you will be able to accept a partial fill to increase your chance of a successful execution.

If you choose to use this feature, IG will only ever partially fill your order as an alternative to an outright rejection. IG will never partially fill your order as an alternative to filling it in its entirety. So if you trade in a size so large that we cannot fill your entire order rather than reject your entire order IG will be able to fill you in the maximum size possible. 

If you have selected the partial fill feature, the next time you trade through the same device it will be retained as your default option. It will, however, need to be activated independently on different devices e.g. going from your desktop trading platform to using your account through an app.

Are partial fills for me?
Partial fills may be for you if you are a client who wants as much of your order filled as possible at the current price, and do not want a size rejection just because IG cannot fill the entire order.


IG’s current FTSE price is 6799-6800. You want to buy up to £2000 per point at 6800, but you are worried your order may be size rejected as it is so big.

You submit an order to buy £2000 per point at 6800, and select ‘accept partial fill’ on the deal ticket

IG tries to fill you in the whole £2000 per point, but as the order is so big you receive a partial fill in £1700 per point. If you had not ‘accepted partial fill’ your entire order would have been rejected. The remaining part of your order (£300) will be cancelled.

Points through current

Points through current will give you even more control of your execution by allowing you to trade through the current IG price. This new feature will reduce your chance of a price rejection in volatile market conditions, and increase your likelihood of successful execution when you are trading in large sizes.

While IG will still fill your order at the best possible price, you can rest assured that, like partials, the chance of a successful execution is increased when using ‘points through current.

Is points through current for me?
Points through current may be for you if you are a client who wants to minimise the change of a price rejection due to volatile markets.


IG’s current FTSE price is 6799-6800, but the market is very volatile and you want to reduce your chance of getting a price rejection when you buy £10 per point.

You submit an order to buy £10 per point of FTSE up to 2 points through the current price. You are telling IG you are willing to pay up to 6802 (6800+2) to reduce your chance of a price rejection as you know the market is volatile. When IG receives your order our FTSE price has gone down 1 point to 6798-6799 and you get filled in £10 per point at 6799.

How we source the best prices

We source our prices from a large number of venues to help us give you the best price we can:

  • Our forex and some other market prices are sourced from top global banks and exchanges
  • We use primary exchanges like the ASX and our multi-venue technology to source shares prices from leading exchanges, including BATS and Chi-X Europe.
  • This means you get greater liquidity and can access the best prices from around the globe, and it means we can continue to quote even if an exchange goes down
  • We make our own prices for markets such as binaries and for out-of-hours markets

How we give you the best price

  • We guarantee we will never fill your trade at a level worse than the one you requested, and if the market moves against you when you click to trade, we'll ask you to resubmit your order rather than filling it at a price you don't want.
  • And when markets can change in milliseconds, our Price Improvement technology means if a better price becomes available as you click to trade, we may give you that price.
  • Our clients saved over £42 million thanks to Price Improvement (since January 2013)

Which prices are live?

The majority of our prices are live for active clients.

For Australian share CFDs, prices will be delayed by 20 minutes, but within deal tickets prices will be shown live at the point of dealing. Clients have to subscribe to get continual live prices from within the platform – this does incur a fee from any exchange you subscribe to, but exchange fees are refunded if a minimum number of transactions are made in a month.

ProRealTime chart prices are also live, and incur a fee of $60 per month if clients subscribe. Again, this fee is refunded if at least four trades are transacted in a given month.

Live DMA price feeds are also chargeable, but refunded in the same manner.



DMA pricing technology

  • Best possible prices due to aggregated prices from multiple exchanges
  • Better execution thanks to increased liquidity
  • Technology that automatically hunts down the optimum prices
  • Free live price feeds from MTFs

How does it work?


When you are trading share CFDs and you click on one of the prices in our DMA platforms, the smart order routing technology immediately routes your order to the relevant venue. By routing your order across multiple order books it's more likely that your order will be filled, but you will only ever be charged one commission per order.

If your requested size and price is not available, your order will be routed to the primary exchange, where the greatest level of liquidity is generally available.

More about shares DMA

MTF lit books

Multilateral Trading Facilities (MTFs) provide visible order books in the same way primary exchanges do, so you can see the price and size of all orders and judge where you want to place yours. We combine these MTF lit books and the primary exchange order book to display a single, aggregated order book.

If you are using our L2 Dealer platform, you can view the individual order books for each exchange and MTF.

Dark pools


Our technology also connects you to the dark pools provided by MTFs like Delta or BATS Europe’s Dark Pool. These are orders not displayed on the lit books but are available for you to trade against. Dark liquidity pools are often used by institutional investors who do not wish to reveal the price, size and origin of their orders.

This means that as well as the liquidity visible on the lit order books, trading share CFDs with IG gives you access to the non-displayed liquidity found in the dark pools. This means you can take advantage of even greater levels of liquidity, increasing the likelihood of your orders being filled and the potential for better prices.

Better prices

Previously, MTF lit and dark liquidity was only available to large institutional investors; we enable all CFD traders to access these new venues through our DMA trading solutions.


All our platforms use top-level web security, so you can trade with confidence.

We utilise 256-bit SSL (Secure Sockets Layer) encryption, which is the industry standard for online financial transactions, from PayPal and eBay to major banking institutions.
