This Expert Advisor is purely a diagnostic tool: it does not open any trades, but analyses and ‘captures a snapshot’ of the environment in which MetaTrader 5 is running.
Once launched on the chart, it collects all the broker’s technical specifications and displays them in three ways:
- The chart panel at the top left of the chart (with data updated in real time).
- Terminal log (the ‘Experts’ tab at the bottom).
- CSV file (saved in the MQL5/Files folder on your PC).
What information does it extract?
The EA reads dozens of vital parameters in real time, grouping them by category:
- Time Zone (Crucial): Calculates the broker’s server time, your PC’s time and the exact difference between the server time and UTC (Greenwich) time.
- Trading Costs: Extracts the swap calculation method, the long and short swap values in real currency (per 1 lot), and the current spread.
- Symbol Rules: Digits (decimals), contract size, minimum/maximum/step volume, Stop Levels (minimum distance for placing Stop Loss and Take Profit orders) and Freeze Level.
- Execution and Connection: Ping in milliseconds (latency), connection status, order filling modes accepted by the broker (FOK, IOC) and margin calculation method.
- Account: Broker name, server, account currency, leverage and equity.

Contract Sizer: ladder, floor and a breaker that survives a deposit
Three position-sizing protections that do different things; confusing them is why so many accounts get wiped out: - ladder: one contract per X of balance, always applied as a CAP, even with manual lot sizing; - floor: below the minimum capital it does not trade; a new deposit is needed; - breaker: stops at X% below the peak, at any account size, and does not rearm by itself. What this library solves and almost none does: a deposit is not profit, and a withdrawal is not a loss. The breaker measures the drop against the balance peak. Untreated, a deposit made DURING a drawdown lifts balance and peak together, and the protection stops seeing the drop exactly when it would help. Here deposits and withdrawals shift the peak by the same amount. The peak is persisted to a file: a breaker that forgets the peak on a terminal restart is not a breaker. The demo simulates a deposit at the bottom of a drawdown. Run it with the deposit on and off and compare the "drop" column.
Safe Logger: why your log lines vanish while FileOpen keeps returning success
Four EAs writing to the same file, all with FILE_SHARE_READ|FILE_SHARE_WRITE, FileSeek(SEEK_END), FileWrite, FileClose. Looks correct. Every FileOpen returns success. No error in the log. And the lines vanish. Reason: FILE_SHARE_WRITE lets all four open at the same time. All four call FileSeek(SEEK_END) and get THE SAME offset, because none has written yet. All four write at the same position. Whoever closes last wins. Three lines vanish silently. In my case: 12 events expected, 8 in the file. The fix is to open EXCLUSIVELY (no FILE_SHARE_WRITE) and retry while another EA holds the file. And to shout in the log when the retries run out: a log that fails silently is worse than no log at all, because you trust it. The demo script reproduces both modes. To see the loss, drag it onto four charts at the same time with safe mode off and count the lines in the CSV. On a single chart the defect does not show up - which is why it passes in testing and breaks in production.
