A

Ask

Trading

Price at which the broker/dealer is willing to sell. Same as "Offer".

B

Bid

Trading

Price at which the broker/dealer is willing to buy.

Bid/Ask Spread (or "Spread")

Trading

The distance, usually measured in pips, between the bid and ask price. A tighter spread is better for the trader — it means lower transaction costs.

C

Cost of Carry (also "Interest" or "Premium")

Trading

The cost, often quoted in dollars or pips per day, of holding an open position. See also Premium.

Currency Futures

Market Structure

Futures contracts traded on an exchange, most typically the Chicago Mercantile Exchange (CME). Always quoted in terms of the currency value with respect to the US Dollar. Parameters of the futures contract are standardized by the exchange.

Compare to Spot Foreign Exchange — GCI offers spot, not futures.
D

Drawdown

Risk

The magnitude of a decline in account value, in percentage or dollar terms, measured from peak to subsequent trough.

Example
If a trader's account goes from $10,000 → $20,000 → $15,000 → $25,000, their maximum drawdown is $5,000 (the $20K to $15K decline) — even though the account was never below the starting balance.
E

EBS

Market Structure

"Electronic Brokerage System" — one of the major electronic platforms on which banks trade with each other. Historically considered the definitive indicator of where currencies (particularly EUR/USD and USD/JPY) are really trading. Today, EBS shares the interbank market with Refinitiv/LSEG Matching and other venues.

F

Forex

Market Structure

Short for "Foreign Exchange." Refers generally to the foreign exchange trading industry and/or the currencies themselves.

Fundamental Analysis

Analysis

Macro or strategic assessments of where a currency should be trading based on any criteria other than the price action itself. Common inputs include the economic condition of the country the currency represents, monetary policy decisions, interest rates, and inflation data.

The opposite approach is Technical Analysis.
L

Leverage

Risk

The amount, expressed as a multiple, by which the notional amount traded exceeds the margin required to trade.

Example
If the notional amount traded ("lot size") is $100,000 and the required margin is $2,000, the trader is using 50× leverage ($100,000 / $2,000).

Limit

Trading

An order to buy at a specified price when the market moves down to that price, or sell at a specified price when the market moves up to that price. Compare to Stop and Market Order.

Liquidity

Market Structure

A function of volume and activity in a market — the efficiency and cost-effectiveness with which positions can be traded and orders executed. A more liquid market provides more frequent price quotes at a smaller bid/ask spread.

M

Margin

Risk

The amount of funds required in a client's account in order to open or maintain an open position.

Example
1% margin means $1,000 of funds on deposit are required to open a $100,000 position.

Margin Call

Risk

A requirement by the broker to deposit more funds in order to maintain an open position. Sometimes "margin call" means that a position without sufficient funds on deposit will be closed out automatically by the broker — this procedure allows the client to avoid further losses or a debit account balance.

Market Order

Trading

An order to buy or sell immediately at the current market price — buying at the current Ask, selling at the current Bid.

O

Offer

Trading

Price at which the broker/dealer is willing to sell. Same as Ask.

P

Pip

Trading

The smallest standard price increment in a currency pair. Often referred to as a "tick" in futures markets.

Example
In EUR/USD, a move from 1.08501.0851 is one pip.
In USD/JPY, a move from 148.51148.52 is one pip.

Premium (also "Interest" or "Cost of Carry")

Trading

The cost, often quoted in dollars or pips per day, of holding an open position. Identical to Cost of Carry.

R

Rollover

Market Structure

The process of moving from an expiring futures contract to the next contract month. In spot forex, "rollover" also refers to the daily interest charge or credit applied to positions held overnight.

S

Spot Foreign Exchange

Market Structure

Often called the "interbank" market. Refers to currencies traded between two counterparties, often major banks. Spot Foreign Exchange is generally traded on margin and is the primary market this website focuses on. Generally more liquid and more widely traded than currency futures, particularly by institutions and professional money managers.

Stop

Risk

An order to buy at the market only when the market moves up to a specific price, or sell at the market only when the market moves down to a specific price. Most commonly used as a "stop-loss" — to cap losses on an existing position.

T

Technical Analysis

Analysis

Analysis applied to the price action of the market itself to develop trading decisions, irrespective of fundamental factors. Tools include chart patterns, indicators (moving averages, RSI, MACD), and support/resistance levels.

The opposite approach is Fundamental Analysis.

Tick

Trading

The smallest price increment in a futures or CFD price. Often called a "pip" in the currency markets.

Example
In Dow Jones Industrial Average futures, a move from 42,15042,151 is one tick.
In S&P 500 e-mini, a move from 5,840.005,840.25 is one tick.
