QuAI EA Preflight Check
- Utilitaires
- Version: 1.0
QuAI EA Preflight Check is a free MetaTrader 5 utility designed to answer one simple question before you run an Expert Advisor:
Is this account, broker and symbol environment compatible with the EA settings you intend to use?
Instead of showing only raw account information, the utility performs a practical preflight diagnostic and classifies the most important conditions as PASS, WARN or FAIL.
The tool never opens, modifies or closes trades.

EA scenario inputs
You can define the conditions your EA is expected to use:
- Base lot
- Maximum concurrent positions
- Maximum total lots
- Planned Stop Loss distance
- Planned Take Profit distance
- Reference adverse move
- Minimum acceptable margin level
- Maximum acceptable spread
This allows the same broker and symbol to be tested against different EA requirements.
Example
An EA may be perfectly valid on one broker but incompatible on another because:
- the minimum lot is too high;
- the lot step does not match the requested volume;
- Stops Level is larger than the EA's intended SL;
- Freeze Level restricts trade modification;
- the account is netting when the EA was designed for hedging;
- the spread is above the EA's intended limit;
- the available margin is insufficient for the planned exposure.
QuAI EA Preflight Check makes these conditions visible before you rely on the EA.
PASS / WARN / FAIL
PASS
The checked condition is compatible with the configured scenario.
WARN
The EA may still operate, but the condition deserves attention.
FAIL
The condition can prevent trading or make the configured scenario incompatible with the current environment.
A PASS result is not a guarantee that any specific EA will trade or be profitable. The utility checks infrastructure and risk conditions, not the strategy logic inside another EA.
Projected margin level
The tool estimates the margin level that could result from the configured maximum total lots using the current account equity, existing margin and the symbol's current margin requirements.
This is a practical preflight estimate, not a simulation of future price movement.

Report export
The current diagnostic can be exported as a text report to the MetaTrader 5 Files folder.
This is useful when:
- comparing brokers;
- comparing symbols;
- checking a VPS or new trading account;
- documenting the environment used by an EA;
- troubleshooting why an EA does not open trades.
Who is it for?
QuAI EA Preflight Check is useful for:
- automated-trading users;
- EA developers;
- traders moving an EA to a new broker;
- traders comparing real and demo accounts;
- users troubleshooting an EA that is not trading;
- grid, recovery, scalping and swing-system users.
