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:

Over 22 million orders accepted (Apr-Jun 2016)

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

More than 42,000 unique daily web users (August 2016)
More than 52,000 unique daily mobile users (August 2016)

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 in the dealing platform and the latest version of the IG mobile trading app

Partial fills

We’re the first in the industry to offer clients partial fills on their online trades. If you are a client who trades in large sizes 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, for example 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.

Points through current

Points through current gives 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?

Point through current may be for you if you are a client who wants to minimise the chance of a price rejection due to volatile markets.

How we source the best prices

We source our prices from a large number of venues to make sure we 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 LSE and our multi-venue technology to source share prices from two of Europe’s leading exchanges, Chi-X and BATS
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
For some illiquid shares we use market-maker prices
We make our own prices for markets such as digital 100s and for out of hours markets

How we give you the best price

Markets can move in milliseconds, meaning the price you click to trade on may have changed by the time your order reaches us.

To protect you from this, we guarantee that we will never fill an order at a level worse than the one you requested.

A symmetrical tolerance level is set a certain distance either side of your requested price – if the market stays within this threshold by the time we receive your order, your order will be executed at the level you requested.
Should the movement take the price outside this threshold, we will do one of two things:

If the market moves to a price that would be better for you, our price improvement technology will ensure you receive that price. We’ve saved our clients over £55 million in this way since January 2013.
If the price moves beyond our tolerance in the opposite direction, we’ll reject the order and ask you to resubmit.

Which prices are live?

The majority of our prices are live for active clients.

For equity markets, we offer four different types of price feed:

• Delayed prices

15 or 20 minutes behind the exchange price. Free of charge

• Derived prices

time prices created from the raw data of one or more exchanges. Free of charge

• Level 1

Real-time prices from the top level of the exchange order book. Charges may apply if you upgrade to this data feed

• Level 2

Real time prices from the top five levels of the exchange order book. Charges may apply if you upgrade to this data feed

We display delayed prices by default on all equity markets, unless we can offer another free data option, such as pricing from multilateral trading facilities (MTFs) or derived prices.

You can see raw exchange prices if you upgrade your data feeds or use our DMA platform. Upgrading 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.

Please note that execution is always against the true exchange price, and will be at the best price that we can source from multiple trading venues.

ProRealTime chart prices are also live, and incur a fee of £30 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.
