Enable 'Algo Trading' on the MT5 toolbar.

In gonisshi.com:

EA Inputs

Input Field
Default Value
Description

ApiKey
(empty)
Your sync key obtained from gonisshi.com Import → Broker sync. This is required and must be at least 8 characters long.

ApiBaseUrl
API origin. This must be added to the allowed WebRequest URLs in MT5 settings.

SyncIntervalSeconds
60
Specifies how often the EA polls for new closed trades. The minimum interval is 30 seconds.

MaxBackfillTrades
10000
The maximum number of closed trades to upload when the EA first connects or after a reset.

MaxBackfillDays
730
Sets the historical data range for backfilling, covering approximately 2 years of closed trades.



Functionality Overview

The EA performs the following actions:

Checks the health of the API endpoint at /api/ea-sync/.
Registers your account details (login, server, company, currency) with the service.
Backfills recently closed deals (types: OUT, INOUT, OUT_BY) that are newer than the last synced record.
Periodically posts batches of new closed trades or a simple heartbeat if no new trades are available.
Stores connection information and the ticket number of the last synced position in a shared file, allowing restarts to resume from the last point.
If an HTTP 401 error (revoked key) is encountered, the EA will alert you and stop its timer.
If a 403/404 error (stale connection) occurs, the EA clears the saved state and re-registers the account.



Limitations

Open positions are not synchronized until they are closed.

The synchronization cursor tracks the last synced position ID. Trades opened before the cursor was updated but closed later might be skipped. The initial backfill process covers closed history within the specified day and trade limits.

This EA does not place trades. It is safe to use on a live account for journaling purposes only.



Troubleshooting Common Issues

No logs are appearing: Ensure you are checking the 'Experts' tab in the MT5 Toolbox, not the 'Journal' tab.

WebRequest error 4060: Add the 'ApiBaseUrl' to your allowed URLs in MT5 settings and restart MT5.

HTTP 401 error: Generate a new API key within the gonisshi.com application.

Stale connection (HTTP 403): Remove the EA from the chart, then re-attach it with a newly generated API key.
