What is Constans
Software that trades your challenge by rules.
Constans is a trading engine from Switzerland for prop-firm accounts. It runs on your own MetaTrader 5, stays well inside your prop firm's limits and shows every decision it makes.
How the engine decides
One market. One rule. The same every day.
The engine trades only the Nasdaq 100 – and only when price clearly breaks out of its normal range. It checks every 30 minutes and is always flat by the market close.

Monitoring
The engine never sleeps.
Many bots place an order and wait. The Constans Engine checks your account against the market every 10 seconds: is the position still valid? Is the risk still right? How far away is every limit? If something is off, it steps in by fixed rules – as long as your MetaTrader 5 is running.

Risk first
We brake before FTMO does.
Most challenges don't fail on the market – they fail on one bad day. The engine keeps its distance from every limit, automatically and without exception.

Questions
Frequently asked
Do I get new versions of the engine?
Yes, at no extra cost for as long as your membership runs. We only release new versions once they have passed on historical data and then in a forward test on our own account. Updates arrive through our server – no new file, no reinstall. For strategy updates you see the changelog in the Console and decide yourself when to switch – for example not in the middle of a challenge. A new version is no promise of better results.
Does Constans Engine comply with FTMO rules?
It is built around FTMO's rules: at most 2 % risk per trade, its own daily brake at −3.5 % (FTMO allows 5 %), an overall brake at −9 % (FTMO allows 10 %), no positions overnight and only a few trades per week. Compliance with a specific firm at a specific time is your responsibility – rules change, and firms differ in how they treat third-party tools.
Which account type do I need?
A Swing account. The engine holds nothing overnight, so that is not the reason. The reason is FTMO's news rule: on Standard accounts, once funded, any execution 2 minutes before and after major US economic releases is prohibited. The engine has no news filter, and its check times land exactly on such releases: data at 16:00 and the Fed rate decision at 20:00 Swiss time. So buy the Swing variant of the challenge.
Is there a free trial?
No. There is a 14-day satisfaction guarantee instead: if you are not happy with the software or the service, you get your money back.
What exactly am I buying?
A software license. Constans Engine is an expert advisor for MetaTrader 5 that runs on your own terminal and executes a fixed, rule-based strategy on your account. The membership includes the engine, the Console, the rule profiles and all updates.
Built to stay inside the rules.
