What is an equity stop?
Published: · by the QuantGovernor team
An equity stop is a portfolio-level protection: when the account's equity — balance plus the floating result of open positions — falls to a declared threshold, every position is closed automatically to preserve the remaining capital. Where a stop loss protects a single trade, an equity stop protects the account as a whole. It is the master control above every other rule.
How it works, mechanically
The mechanism watches one number: current equity versus a reference level. Take a concrete case — the one we actually run: Olympus declares an equity stop at −30%. If the combined floating and realized losses of the whole portfolio ever push equity 30% below its reference, the system liquidates everything — every strategy, every open position, including the components that were profitable at that moment. No exceptions, no "let's wait and see": that discretionality is precisely what the mechanism exists to remove.
Equity stop vs stop loss: different jobs
- A stop loss answers: "how much can this one trade lose?" It caps individual mistakes.
- An equity stop answers: "how much can this account lose before everything shuts down?" It caps the accumulation — many small losses, correlated positions losing together, or a strategy component behaving badly.
The two are complements, not alternatives. A portfolio can bleed to death through trades that each respected their stop loss; only an account-level threshold catches that. Conversely, an equity stop alone leaves single trades unguarded on instruments where per-trade stops are possible. In our systems, strategies that can carry a per-trade stop do — and the portfolio threshold sits above everything, including components managed at the equity level.
Why declare it publicly?
A risk limit that lives in the manager's head is a mood, not a rule. Declaring the threshold on the strategy's page does two things: it forces the discipline (the number is now a commitment, verifiable against the track record), and it lets an investor decide in advance whether that worst case is acceptable for their capital. If a −30% scenario is not something you could live with, the right moment to find out is before connecting, not during.
The honest limits
An equity stop is a target, not a force field. Its execution depends on the market being open and liquid: a weekend gap, a flash move with no liquidity, or extreme slippage can push the final loss beyond the declared threshold before orders can fill. This is not a defect of the mechanism — it is a property of markets, and it is why our Risk Disclosure states that declared limits can be exceeded in extreme conditions. A provider who presents an equity stop as an absolute guarantee is misdescribing how markets work.
What to check on any strategy
- Is there a portfolio-level threshold at all — or only per-trade stops, or nothing?
- Is it declared publicly, with a number, before you invest?
- Is it automatic, or does someone have to decide to pull the trigger?
- Does the live track record's worst drawdown sit comfortably inside it?
