Brokers have been competing on handing out low stop-out levels from 20% all the way down to 0%. While this seems like an edge for traders, allowing for more ‘breathing room’ during drawdowns, this is only true to some extent.
Like leverage, low stop-outs are a double-edged tool: they offer flexibility, but can also make liquidation devastatingly real for those who misunderstand their purpose.
In this quick guide, we’ll walk you through:
- Why it works for brokers
- What are the benefits and the risks for traders
- How to use low stop-outs safely
- Who these levels are and aren’t for
Why brokers offer low stop-outs
First let’s make a distinction. A margin call is a warning that your equity has fallen to a threshold, usually 100% of used margin. A stop-out is automatic liquidation. When your equity falls to the stop-out percentage, normally 50% of used margin, the broker starts to close positions.
For example, with $1,000 as margin the calculation is straightforward:
- At 50% stop-out, positions close when equity reaches $500.
- At 20%, liquidation only starts when equity hits $200. You would lose $800 before anything gets triggered, a huge drawdown by any measure!
Why do more brokers offer lower thresholds? Well, it complements high leverage and appeals to aggressive strategies. However, there’s a crucial difference between broker’s and traders’ risk perspective: low stop-out levels protect the broker’s exposure before your account goes negative, they don’t protect your capital.
As over 80% of retail traders lose, low levels allow them to lose more before being stopped out. The only inconvenience for the broker is that they will need to wait a bit longer before closing you out.
The benefits and the risks of low stop-outs
Still, low stop-outs do offer legitimate advantages if you know how to use them, just like high leverage. They provide room for trades during short-term volatility without premature liquidation. For traders managing hedged positions or multiple trades, such thresholds offer portfolio flexibility.
However, the dangers are real as larger losses may compound instead of being stopped. In our 50% vs. 20% example, the latter would result in 60% more loss!
More problematic is that they create a false sense of security. Traders may overtrade or oversize, believing they have enough margin buffer. The psychological trap is dangerous: ‘It hasn’t hit stop-out yet’ becomes justification for inaction as losses mount.
The reality is that most blown accounts had plenty of margin, until they didn’t. A news event, overnight gap or flash crash can obliterate buffers in seconds, and by the time stop-out triggers at 20%, the damage is done.
How to use low levels safely
The fundamental principle to understand is that a stop-out is not a stop loss. As such, your broker’s level is an emergency failsafe, never your own risk parameter.
Winners’ trading habits start by establishing personal risk rules which include:
- Position size based on risk per trade, 1-2% of account equity
- Each trade with a mandatory stop loss from analysis
- Potential spread widening and gaps
- Margin usage limits well below maximum allowed
Professional traders often use less than 10% of available margin, understanding that margin availability and risk management are separate concerns.
One last thing: slippage can push through your stop-outs faster than expected. Therefore, you must size conservatively and use tight stop losses.
Who low stop-outs are and aren’t for
These are the traders who can make the most of low levels without endangering their accounts:
- Experienced ones who understand margin mechanics and maintain discipline
- Strategy-based traders with calculated drawdown parameters
- Traders managing multiple hedged positions without netting
They’re unsuitable for:
- Beginners still learning risk management
- High-leverage scalpers without adequate buffers
Traders relying on broker safeguards instead of personal discipline will find out that low stop-outs reward bad habits until they don’t.
What to check before choosing a low stop-out
If a broker highlights their low levels explaining risks or policies clearly, that’s a red flag. Here are a few things to be aware of when going with a broker offering a lower level.
First, make sure whether the thresholds are fixed or dynamic. Next, you need to understand how positions are liquidated: starting from the biggest losses, or all at once?
It’s worthwhile checking spread behaviour near the margin level as some brokers widen spreads when accounts approach stop-out. And to prepare for the worst, see if negative balance protection can be applied and understand its conditions.

Common myths about low stop-outs
Finally, here are some myths to clear so traders can set the right expectations.
‘Lower stop-out means lower risk’: You can lose more before liquidation, which is the opposite of lower risk.
‘I can trade bigger positions safely’: Position size should be determined by your risk per trade, not the broker’s margin requirements.
‘The broker will close trades at the best time’: Stop-out is for the broker’s sake, not your trading strategy, as liquidation may trigger at the worst moment.
Conclusion
Low stop-out levels offer valuable flexibility for experienced traders, but can exacerbate drawdowns for those still learning risk management skills.
They reward discipline and punish overconfidence. The best traders rarely approach these levels, regardless of percentage, because they control position sizing, stop losses and margin usage.
