Margin Level

Margin level is the ratio of a trading account's equity to its used margin, expressed as a percentage: Margin Level = (Equity / Used Margin) x 100 Where: - Equity = account balance plus or minus the floating profit/loss of all open positions. - Used Margin = the total funds the broker has locked as collateral to keep current positions open. The percentage rises as equity grows relative to the committed margin and falls as floating losses erode equity. A reading well above 100% generally indicates a comfortable buffer, while readings approaching or below 100% indicate the account is highly stressed. Most brokers define two specific trigger points relative to this figure: a margin-call level (a warning threshold) and a stop-out level (the point at which positions are force-closed). Exact thresholds vary by broker and account type, so they should always be read from the broker's own terms. When no positions are open, used margin is zero and margin level is typically shown as undefined or infinite.

In plain English — Margin level is a health gauge for a leveraged trading account. When you open positions using leverage, your broker sets aside part of your funds as "used margin" (the collateral holding the trades open). Margin level measures your live equity against that used margin and shows the result as a percentage. Think of it like the fuel gauge in a car: a high reading means you have plenty of buffer to keep trading and absorb losing moves, while a low reading warns you are running close to empty. As open trades move against you, your equity falls, the percentage drops, and the warning lights start coming on. Brokers watch this number constantly. If it falls past certain thresholds, the broker first warns you (a margin call), and if it keeps dropping, it may automatically close some or all of your positions (a stop-out) to stop the account from going negative. Understanding margin level helps a trader see, at a glance, how exposed an account is before the broker steps in.

Suppose a trader's account has 1,000 units of equity and they open positions that require 200 units of used margin as collateral. Margin Level = (1,000 / 200) x 100 = 500% This is a wide buffer. Now imagine the open trades move against the trader and show a floating loss of 600 units. Equity falls to 1,000 - 600 = 400 units, while used margin stays at 200: Margin Level = (400 / 200) x 100 = 200% The trades keep moving against them and the floating loss reaches 850 units. Equity drops to 150: Margin Level = (150 / 200) x 100 = 75% At 75% the account is below the common 100% reference point. Depending on the broker's published thresholds, the trader may have already received a margin-call warning and could be approaching a stop-out, where the broker automatically closes positions. This example uses round numbers purely to show the mechanics and is not a recommendation about position size or leverage.
