This might sound strange…but when a broker modifies MT4 (e.g., because they’re an ECN)…can that version of MT4 send the broker the EA’s you write? Not that I have a holy grail or anything. But life has taught me that if there’s money involved…anything can (and often does) happen. Anything…
One observation…
If I move an EA into the experts folder using Windows Explorer, I can see it later from Windows Explorer.
If I create an EA from the MetaEditor and save/compile it in the experts folder, I can’t see it from Windows Explorer. So where is it saved? As an appendage to some MetaTrader file? Which they (the broker) is allowed to read, right?..to notify users of updates, etc.
