Bet sizeGoverns how much you make or lose on a spread bet for every point of movement in the price of the market
BidA spread betting price is made up of a level at which you can 'sell' and a level at which you can 'buy'. The level at which you can 'sell' is always the lower
BinaryA binary allows you to take a view on whether a specific outcome will or won't occur. For example, 'Will Wall Street be up at the close of the day?' If the answer is 'yes', the binary settles at 100. If the answer is 'no', the binary settles at 0. Your profit or loss is the difference between 100 (if the event occurs) or zero (if the event doesn't occur) and the level at which you 'bought' or 'sold'. Binary prices can be extremely volatile even when the underlying market is relatively static. A small movement in the underlying can make all the difference between the binary settling at 0 or 100
BuyYou 'buy' a market if you think it will rise (if you are opening a new trade or bet). You also 'buy' to close out an existing 'sell' trade or bet
CFDContract for difference
ClosingThe process of ending an existing trade or bet. Closing the position results in a profit or loss being realised

Force openEnabling force open when creating a new position or working order will enable a second position to be opened on a market. Working orders (orders to open) have this set to true by default.
Guaranteed stopA stop-loss order that puts an absolute limit on your liability, eliminating the chance of slippage and guaranteeing an exit price for your trade. Please note that guaranteed stops come at the price of an increased spread
InstrumentIG tradeable financial instrument (market), typically based on some underlying financial market instrument. Since our instruments are derived, they do not have recognisable real-world identifiers such as the Reuters or Bloomberg codes. Instead, IGs instruments are identified by proprietary identifiers known as EPICs. KA.D.VOD.CASH.IP, for example, is the EPIC for IG’s Vodafone spot (as opposed to futures) instrument. The IG instrument EPICs for an underlying market of interest may be determined via our API’s set of /market services. Please note that in the case of expiring time-based instruments, the IG instrument is 'rolled' over to the next interval, and so will represent a different underlying instrument, even though the EPIC is unchanged
Instrument typeA type of IG tradeable financial instrument, eg Binary
LevelInstrument price

L1Level 1 pricing refers to the current best bid and offer levels
L2Level 2 pricing is relevant for direct market access (DMA) products. As well as showing the best bid and offer you can also view the market depth. Market depth displays the liquidity in the instrument in more detail, listing other buyers and sellers and the size they are willing to trade in below and above the current bid/offer levels
Limit working orderAn instruction to deal if the price moves to a more favourable level, eg to 'buy' if the price goes down to a specified level
Liquid marketA liquid market has a sufficient volume of two-way business for a trade to occur without moving prices unduly. The market will normally exhibit narrow bid-offer spreads
Lot sizeMinimum amount of unit that an instrument can be dealt in the market. It's the relationship between unit and the amount per point
MarginThe amount required from a client (in addition to any deposit due) to cover losses when a price moves adversely. Sometimes called variation margin
MarketA financial market, which may refer to an underlying financial market, or the market being offered in terms of an IG instrument. IG instruments are organised in the form a navigable market hierarchy
Market identifierThe name of a natural grouping of a set of IG markets, typically representing the underlying 'real-world' market. For example, VOD-UK represents Vodafone Group PLC (UK). This identifier is primarily used in the our market research services, such as client sentiment, and may be found on the /market/{epic} service
Market orderAn order that you use to specify the direction and size of a bet, but not the price. This ensures we will fill your order as quickly as possible, even if the price indicated on the deal ticket is not available for your requested order size
OfferA CFD or spread betting price is made up of a level at which you can 'sell' and a level at which you can 'buy'. The level at which you can 'buy' is the higher of the two prices and is called the offer

RolloverWhere a trade or bet approaching expiry is closed and a position of the same size and direction is opened for the next period, thereby prolonging the exposure to a particular market
Scaling factorScaling factor to be used to multiply/divide the level values for an instrument in order to calculate market exposure
SellYou 'sell' a market if you think it will fall (if you are opening a new trade or bet). You also 'sell' to close out an existing 'buy' position
SlippageThe difference between the level of a stop order and the actual price at which it was executed. Slippage can occur during periods of higher volatility when market prices move rapidly or gap
SpreadThe difference between the 'buying' and 'selling' price
Spread betA bet on whether a financial market (the underlying market) will rise or fall. We offer two prices on every market; the difference is known as the bid/offer spread. If you think a market is set to rise you 'buy' at the higher (or offer) price, and if you think it will fall you 'sell' at the lower (bid) price. Whether you gain or lose money on the bet – and how much – depends on the size/direction of any movement in the underlying market. Only available in the UK
Stop orderAn instruction to deal if the price becomes less favourable; normally placed to prevent a loss of more than a certain amount of money
