The FLR caps how much you can lose on a single trade — measured as a percentage of your balance right before that trade, not your starting balance. Size a position so you never cross it, or check a trade before you click.

Firms with no per-trade cap. These firms in our database don’t cap single-trade loss, so the FLR rule never applies:
It’s a hard limit on how much you can lose on any single trade, written as a percentage of your account balance just before that trade. If a firm sets a 2% FLR and your balance is $100,000, no one trade may lose more than $2,000. Go past it and the account can be breached even if your overall drawdown is fine.
How do I size a trade to stay under it?
Take your max loss (balance × FLR%), then divide by the cash risk of a 1.00 lot at your stop distance. Max lots = max loss ÷ (stop distance × value per lot). The sizer tab does exactly this — punch in balance, cap, instrument and stop, and it returns the largest position that still respects the cap.
Is the cap based on starting balance or current balance?
On this tool, current balance — the balance right before the trade. Most firms that run a per-trade cap recalculate it against your live balance, so as your account grows the dollar cap grows with it, and as it shrinks the cap tightens. Always confirm which balance your firm uses.
Why does the contract value matter so much?
Because it converts your stop distance into dollars. The same 50-point stop is a very different dollar risk on US30 versus NAS100 versus gold. The value-per-lot field is pre-filled to typical MT5 CFD specs, but brokers differ — set it to your platform’s real number and the lot result will be exact.
What happens if a single trade breaches the FLR?
Most firms void the trade or fail the account outright, regardless of whether you were green overall. There’s no averaging it out across other trades — the cap is per-trade. The checker tab flags this before you take the trade: anything over 100% of the cap shows as a breach.
