Margin tiers by position size
Posted: Sat Oct 31, 2026 4:35 am
Some brokers apply tiered margin: the larger the total position in a symbol, the higher the margin rate on the part above a threshold. A trader who holds 5 lots on EURUSD might need 1 percent margin on the first 2 lots and 2 percent on the rest.
For small accounts the effect is negligible. A scalper who scales up, perhaps opening several tickets in quick succession, may find an order rejected because the combined size crosses a tier and the required margin jumps.
The info lies in the account's leverage table, which is available on the broker's website, usually buried in the trading conditions section. It lists the thresholds by symbol and the corresponding leverage.
The tiers can also apply across correlated positions on some platforms. Several pairs involving the same currency might count together. That's less common, but it exists.
The rejection error looks identical to the usual "not enough money" message, so it's easy to misread. Checking whether the free margin was really insufficient, or whether a tier boundary was crossed, takes a minute.
If the scaling is part of a strategy, testing it at the intended size on a live account, with a small multiplier, shows how the margin behaves before it matters.
Does margin tiering come into play for your usual position sizes?
