Exness MT5: What Undoes and What Does Not

Measured order execution — Standard

How orders actually filled when real market orders were placed on Exness’s MT5 feed — fill time, slippage and rejects by order size:

Small sample (a few round-trips per size); indicative. The same pricing engine feeds every platform the broker offers.

What the MT5 window takes back, and what it keeps

• Everything about the way a chart looks — timeframe, scale, colours, the applied template, an indicator added or removed — is a view setting, and it goes back by re-applying the previous one.
• Objects drawn on a chart live in the chart and can be deleted or redrawn; the objects list under Ctrl+B is where one is found again after it disappears behind a scroll.
• A pending order is an instruction, not an event: while it has not triggered it can be modified or deleted from the Trade tab and leaves nothing in the account history.
• A market order is an event. Once it is filled, the fill has happened — closing what it opened is a second deal at a second price, not an undo.
• One-click trading is a setting that turns on and off freely; the orders sent while it was on do not turn back with it.

Reversible and irreversible in the MT5 window

The first seconds after a wrong click

The second click usually costs more than the first, so the first move is to send nothing. Nothing on the screen gets worse while it is being read.

Read the Trade tab in the Toolbox, not the chart. It is the only place that answers the actual question — was an instruction sent, or did the click merely draw something. If the tab carries no new line, nothing left the terminal, and the whole incident is a view setting waiting to be re-applied.

If a new line is there, take the direction and the volume from that line rather than from the chart, where the marker looks much the same whichever way round it is. A pending order still listed under Orders can be deleted there and then. A filled position cannot: the only available action is another deal, and it deserves the same deliberateness as a planned one.

Then note the minute. The Journal tab keeps what the terminal sent and when, and it is a far better witness than a recollection formed thirty seconds after the fact.

Settings that feel destroyed and are only files

Most of what feels lost in the terminal is a file. A template overwritten by accident is restored by saving the old arrangement again from any chart that still carries it. A profile that has scrambled the window layout is restored by switching back to the profile saved before it. Both live on the machine, and both can be copied somewhere safe in advance.

The custom settings inside an indicator are the exception worth knowing about: removing the indicator removes them with it, unless the chart was saved as a template first. It is a small loss and a common annoyance, and one template saved at the end of a session prevents all of it.

Why undo is the wrong word for a closed position

There is a habit carried over from every other program on the machine: a wrong action is followed by a reach for undo. The terminal supports that habit exactly as far as the chart, and no further.

A position closed by mistake is not reopened — a new one is opened. It enters at whatever the price is now, it pays the spread again, and it starts its own row in the history. The distinction matters for the record as much as for the arithmetic: the history will show two round turns where the intention was one, and every later reading of that history has to account for it.

That is also the reason the order confirmation dialogue is worth keeping switched on while the layout of the window is still unfamiliar. It converts an irreversible action back into a reversible one, and a dialogue closed with Escape costs nothing.

What to do in the first seconds after an accidental click

1. Send nothing else. Take the hand off the mouse before reading anything.
2. Open the Trade tab in the Toolbox and look for a line that was not there a minute ago.
3. No new line — nothing was sent. Re-apply the template or redraw the object and carry on.
4. A pending order — it is an instruction, not an event: modify or delete it from the same tab.
5. A filled position — read the direction and the volume from the Trade tab, not from the chart marker.
6. Decide the next action as a deal in its own right: there is no undo, only a second deal at the current price.
7. Note the minute, then read the Journal tab, which records what the terminal sent and when.

Delays and slippage may occur. No guarantee of execution speed or precision.
