New to trading? These are the terms worth understanding before you place a trade. Each one has a short definition you can read at a glance, and a ‘more detail’ explanation when you want to go deeper. For quick one-line definitions of everything else, see the full A–Z glossary.
Order types
How you tell the market what you want to do.
Market order
An instruction to buy or sell immediately at the best price currently available.
More detail
Use a market order when getting in or out now matters more than the exact price. In fast markets the fill price can differ slightly from the last quote (see slippage).
Limit order
An order to buy or sell only at a set price or better, which the market has not yet reached.
More detail
A buy limit sits below the current price; a sell limit sits above it. The order only fills if the market trades to your price, so it may never fill.
Stop order
An order that activates once the price reaches a set trigger, used to enter on momentum or to exit.
More detail
A stop to sell sits below the market and is often used as a stop-loss; a stop to buy sits above and can catch a breakout.
Take profit
A preset order that closes a winning position automatically at a chosen level, locking in the result.
More detail
Attaching a take profit means you don’t have to watch the screen to secure a planned exit.
Stop loss
A preset order that closes a position at a chosen level to cap the loss if the market moves against you.
More detail
A stop loss is the single most important risk tool for most traders, it defines your risk before you enter.
Trailing stop
A stop loss that moves with the market in your favour, locking in gains while limiting losses.
More detail
As the price advances, the trailing stop follows at a set distance; it doesn’t move back if the price reverses.
Costs of trading
What a trade actually costs you, shown up front.
Spread
The difference between the buy (ask) and sell (bid) price, and the main cost of trading on most accounts.
More detail
A tighter spread means a lower cost to enter and exit. Spreads are typical minimums and can widen in volatile or thin markets.
Commission
A separate, published charge per lot used on raw-spread accounts in place of a wider spread.
More detail
Raw-style accounts pair very tight spreads with a small commission; all-in accounts fold the cost into the spread and charge no commission.
Swap (overnight financing)
A charge or credit applied when you hold a position past the daily rollover, reflecting the cost of financing it.
More detail
Swaps depend on the instrument and direction and can be positive or negative. A swap-free option is available on some accounts and instruments.
Pip
The standard unit of price movement in forex, usually the fourth decimal place of a quote.
More detail
‘Pip’ stands for ‘point in percentage’. For JPY pairs a pip is the second decimal place. A pipette is a tenth of a pip.
Pip value
How much one pip of movement is worth in money, based on the pair and your trade size.
More detail
Pip value lets you translate a price move into profit or loss, and size a position to the risk you want.
Leverage & margin
How a small deposit can control a larger position, and the risk that brings.
Leverage
Borrowed exposure that lets you control a larger position with a smaller deposit. It magnifies both gains and losses equally.
More detail
Leverage is expressed as a ratio, like 1:100. Higher leverage means a smaller move can have a larger effect on your account, in both directions, so it should be used with care.
Margin
The deposit set aside to open and maintain a leveraged position, expressed as a percentage of the position size.
More detail
Margin isn’t a fee, it’s collateral held while the trade is open, and returned when you close it.
Equity vs balance
Balance is your account before open trades are counted; equity is your balance plus or minus the running profit or loss of open positions.
More detail
Equity is the number that matters while trades are live, margin levels are measured against equity, not balance.
Free margin
The equity you have left to open new positions or absorb losses, after the margin used by open trades.
More detail
When free margin runs low, you can’t open new trades and you move closer to a margin call.
Margin call
A warning that your equity has fallen close to the minimum needed to keep positions open.
More detail
It’s a prompt to add funds or reduce exposure before positions are closed automatically at the stop-out level.
Stop-out level
The point at which positions are closed automatically to prevent further loss once equity falls too low.
More detail
Stop-out protects you and the broker from a runaway loss; negative balance protection backs it up.
Execution & the platform
How and where your orders are filled.
Non-dealing-desk (NDD)
Execution that routes your order to the market without a dealing desk deciding your fill.
More detail
NDD aims to reduce conflicts of interest and give transparent pricing. Bharat Sky uses non-dealing-desk execution across all instruments.
Slippage
The difference between the price you expected and the price your order actually filled at, common in fast markets.
More detail
Slippage can be positive or negative and is most likely around news or in thin liquidity. Stop orders are especially exposed to it.
Lot
A standard unit of trade size. A standard lot is 100,000 units of the base currency; mini and micro lots are smaller.
More detail
Lot size, together with pip value, determines how much each price move is worth. Smaller lots let you manage risk more finely.
Expert Advisor (EA)
An automated program on MetaTrader 5 that opens and manages trades according to rules you set.
More detail
EAs remove emotion and can run around the clock, but they follow their rules exactly, good and bad, so they need testing.
Requote
A message that the price you asked for is no longer available, offering a new one, more common on dealing-desk models.
More detail
Non-dealing-desk execution reduces requotes by filling at the available market price rather than re-offering.
Risk & strategy
The words that keep you safe, and the styles traders use.
Negative balance protection
A safeguard that means you cannot lose more than the funds in your account.
More detail
Even in a sharp, gapping move, your balance won’t go below zero, an important protection on leveraged products.
Drawdown
The fall from a peak in your account value to a subsequent low, a measure of loss over a period.
More detail
Drawdown is a key gauge of risk and consistency; smaller, controlled drawdowns are usually a sign of good risk management.
Risk-to-reward
The ratio between what you risk on a trade and what you aim to gain from it.
More detail
Thinking in risk-to-reward helps you stay profitable even without winning every trade, if your winners outweigh your losers.
Volatility
How much and how quickly a market’s price moves over a given period.
More detail
Higher volatility means larger, faster moves, more opportunity, but more risk. Spreads can widen when volatility spikes.
Hedging
Holding positions that offset each other to reduce exposure to a particular risk.
More detail
Hedging can protect against adverse moves but also caps potential gains, and may carry extra costs.
Scalping vs swing trading
Scalping takes many small, short-lived trades; swing trading holds positions for days to catch larger moves.
More detail
Neither is better, they suit different temperaments, timeframes and costs. Scalpers care most about spreads and speed.
Market terms
The building blocks of what you trade.
CFD
A Contract for Difference, an agreement to exchange the change in an instrument’s price without owning the underlying asset.
More detail
CFDs let you go long or short and use leverage across forex, indices, metals, energies and shares, without owning the asset itself.
Bid / Ask
The sell price (bid) and the buy price (ask) quoted for an instrument; the gap between them is the spread.
More detail
You always buy at the ask and sell at the bid. The bid is lower, the ask is higher.
Long / Short
Going long means buying to profit from a rise; going short means selling to profit from a fall.
More detail
CFDs let you go short as easily as long, so you can seek opportunities in falling markets too.
Base / Quote currency
In a forex pair, the first currency is the base and the second is the quote; the price is how much quote buys one base.
More detail
When you buy EURUSD you buy euros and sell dollars; the quote shows how many dollars one euro costs.
Liquidity
How easily an instrument can be traded without moving its price. Major forex pairs are highly liquid.
More detail
High liquidity usually means tighter spreads and better fills; low liquidity can mean wider spreads and more slippage.
Bull / Bear market
A bull market is a sustained rise in prices; a bear market is a sustained fall.
More detail
The terms describe the broad trend and the mood behind it, optimism versus pessimism.
