Risk & Money ManagementMarket ExposureNet Exposure
Exposure
The total market risk an account carries, measured by the aggregate notional value of its open positions.
What Exposure means
Exposure is found by summing the notional value of every open position, but in currency trading the more useful view breaks that total down by individual currency. Because each pair contains two currencies, positions that look unrelated on a platform blotter can accumulate into a single large directional bet. A trader long EUR/USD, long GBP/USD and short USD/JPY holds three separate tickets but one consolidated short-dollar exposure, and that consolidated figure is the one that determines the day's outcome.
Managing exposure means capping it in aggregate, not merely per trade, and many traders set a limit on total open risk as well as a per-position limit. Counting lots is a poor substitute, because one lot of a low-volatility pair carries far less daily risk than one lot of a volatile exotic. Weighting exposure by average true range or by recent volatility produces a much more comparable picture, and correlation analysis should be applied before positions are treated as independent.
Worked example
Holding one lot of EUR/USD at 1.0850 and one lot of GBP/USD at 1.2700 produces roughly 108,500 plus 127,000 dollars of notional, or about 235,500 dollars of largely short-dollar exposure on a 10,000 dollar account.

Trade with a regulated broker
Understanding the terminology is the cheap part. The expensive part is choosing a counterparty whose execution, financing and withdrawal behaviour match what the marketing implies. Every broker below has been reviewed with a funded live account, and each review states which legal entity and which regulator applies to the account you would actually open.
