How to Avoid a Margin Call

The two lines the broker draws

A margin call is the account's equity falling to the margin the broker is holding for the open positions. Take one lot of the euro against the dollar at 1.17398, the close on 17 December 2025, on a 10,000-dollar example account at 1:30 leverage. The broker holds 3,913 dollars as margin and watches the margin level, equity divided by that margin: 256 per cent at the open. At 100 per cent, 609 pips against, the platform sends the call, a warning. At 50 per cent, 804 pips against, it closes the position itself at whatever price is then on offer. At 0.40 lot the same two lines are 2,109 and 2,696 pips away. Only the size moved them.

The load line on a ship's hull

Picture a ship's hull with a load line painted on it, the mark that says how deep the ship may sit. Load more cargo and the hull sinks lower; past the line, an ordinary wave puts the deck under. A margin call is the water reaching that line. The cargo is the position size, loaded in port before the ship sails; the waves are the market's ordinary movement, the same for every ship; and the freeboard, the height of the deck above the water, is the margin level. The sea did not change between a ship that rides high and one that founders. The loading did, and it was done in port.
