External Change Narrator
An account rarely changes only because the EA watching it decided to change something. Positions get stopped out. Someone closes a trade from their phone between meetings. A second EA on the same account opens its own position, or edits a stop this EA never touched. MT4's own history tab shows what the account looks like now and what it looked like at close time, but nothing narrates the moment a change actually happened, or says plainly what kind of change it was. This EA does that narrating. It never sends a trade itself, so every change it reports is external by definition - there is no "did I cause this" filter to build, only "what changed and how does it read". Each tick it snapshots ticket state - symbol, type, lots, stop-loss, take- profit, open price - and diffs it against the previous snapshot. A new ticket appearing is reported as opened. A stop-loss or take-profit value changing is reported with the before and after value. A pending order's price changing is reported as a modification; a pending order that has filled is reported as triggered. A ticket that vanishes between two snapshots is looked up in trade history and reported with its close price and profit where a history record exists, with a best-effort note when the closing comment looks like a stop-loss or take-profit hit. Every narrated event goes to the Experts log, optionally pops an Alert(), optionally plays a sound, and optionally appends a row to a CSV log file - so a change that happens while nobody is watching the screen is still on record afterward. Notes and limitations - This EA does not trade. It is read-only with respect to the account and safe to run alongside any other EA or manual trading. - The stop-loss/take-profit hit guess on a closed ticket relies on the closing comment MT4 wrote, which is not standardised across every broker - treat it as a hint, not a certainty, and verify from the actual history tab when it matters. - Detection is snapshot-and-diff on a tick-by-tick basis, since MQL4 has no push-style trade event callback. Two changes to the same ticket between two consecutive ticks (rare, but possible on a fast market or a slow chart) would only show the net result, not each intermediate step. - Tracking state lives only in memory for the lifetime of this EA instance; removing it from the chart or restarting the terminal resets the baseline, so the very next tick after that will not narrate anything that changed while it was gone.
