Slippage Monitor MT5: How to Check Your Execution Slippage

MetaTrader 5 has no built-in slippage monitor. No menu item or report prints "your average slippage" for you — the terminal never stores the quote on screen when you click Buy/Sell. So a slippage monitor on MT5 means combining three things: (1) check a single fill in your deal history — open the Toolbox (View → Toolbox, shortcut Ctrl+T), go to the History tab, read the deal's fill price, and compare it with the Bid/Ask you were shown when placing the order; (2) cap future slippage by setting Maximum deviation (in points) on the New Order window; and (3) if you want running statistics, use tick-based tools — the free Slippage Calculator on MQL5 Market or paid utilities like Execution Quality Monitor — that run inside the terminal and log slippage per symbol. This guide walks through each method, when it makes sense, and what it costs.

1. Check one fill in the deal history — the manual baseline

Every executed trade is recorded as a deal in the Toolbox → History tab (View → Toolbox, Ctrl+T): time, symbol, direction, volume, fill price, and the order ticket it belongs to. The Toolbox panel and its tabs are documented in broker help centers. To measure slippage on one trade, compare the fill price with the quote you saw when requesting: a buy filling above the Ask shown in Market Watch, or a sell below the Bid, has slipped by that difference (a fill at a better price is positive slippage). To review many executions at once, right-click the history and save the account report (statement) for the period.

Best for: verifying a single fill after a trade, checking whether your broker executed near the displayed price, and catching bad fills before they become a pattern.

Cost and limits: manual and per-trade only — no totals, no averages. MT5 records the deal price and its order, but not the exact quote displayed at the instant of the request, so your comparison is only as precise as the price you saw. The community regularly asks how to calculate slippage from order history precisely because the terminal won't compute it for you.

2. Set Maximum deviation to cap slippage at order time

When you open the New Order window, MT5 shows the current Bid/Ask and lets you enter a Maximum deviation (in points). The order is only filled within that tolerance — if the market has moved beyond it at execution, the order is not filled at a worse price. If you trade from an EA, the same idea exists as the slippage (deviation) parameter in the trading API, a common topic on the MQL5 forums. This is MT5's only native slippage control.

Best for: entries when you want to refuse genuinely bad fills — around news, in fast markets, or for scalping where a few points matter.

Cost and limits: it's a control, not a monitor — it gives you zero historical statistics. Set it too tight and orders get rejected in fast markets; too loose and it protects nothing. Pair it with method 1 or 3 to learn what deviation is realistic for your symbols.

3. Run a dedicated slippage monitor on MT5

For ongoing numbers, slippage monitoring on MT5 happens through terminal-attached utilities. Free options include the Slippage Calculator on MQL5 Market; paid ones such as Execution Quality Monitor MT5, Execution Cost Ledger, Reality Engine Pro or TradeLens range from about $30 to $300. These compare each deal with the tick stream and produce averages per symbol, session and direction — the closest thing to a true slippage monitor. If you build your own EA, the official Strategy Tester models slippage in points so you can gauge how a strategy degrades under realistic execution.

Best for: frequent traders and EA/algo users who want per-symbol averages, execution-cost trends, and a defensible record when disputing a fill.

Cost and limits: the terminal must keep running 24/5, which in practice means a VPS; paid tools cost money; accuracy depends on what tick data your broker supplies; each tool adds install and setup time. Some broker reports may also include execution details — check your broker's documentation.

Scenario selection

Use them together

These methods are not mutually exclusive. A practical setup: set a reasonable Maximum deviation on your orders, spot-check fills in the History tab after each session, and run a free calculator for a few weeks until you know your typical slippage per symbol. Expectations help: slippage tends to be worse around major news and in thin or volatile markets — a recurring theme in MQL5 community discussions on bad slippage.

A final word on fit: slippage numbers come from the per-deal checks and tick-based tools above, while Camovia Tray speeds up the workflow around them. It turns MT5 (and MT4) into a tray tool, so you can hover the tray icon for live quotes, see your open positions with current profit/loss, and close one with a click (two-step confirm) — without opening the terminal. MT5 connects directly with no EA; MT4 needs a one-time CamoviaBridge setup of about 30 seconds, and AutoTrading (Ctrl+E) must be on before closing. Quote and position data stays on your computer — nothing is uploaded. Use them side by side: the history check answers "how much did I slip"; Camovia Tray answers "what is the market doing now, and what am I holding".
