Margin Call Radar - indicateur pour MetaTrader 5

Margin Call Radar is a read-only risk panel for MetaTrader 5. It answers one question: how far is the account from margin call and stop out, and what happens to the margin level if the market moves against you. The indicator never opens, modifies or closes orders, so it is safe to run next to any other EA or manual trading.

Key Features

• Margin level in percent with color status: green = safe, gold = below margin call, red = below stop out.
• Distance to margin call and to stop out in three units: account currency, percent of equity and points of the whole book.
• Shock scenarios: adverse price move of 1% and 3% across all positions, and an equity drop of 5%, each with the margin level after the shock.
• Hedge-aware: exposure is netted per symbol, so buy 0.01 + sell 0.01 on the same symbol is not counted as double risk.
• Supports brokers with stop out in money (ACCOUNT_STOPOUT_MODE_MONEY) as well as in percent.
• Positions table: symbol, side, volume and P/L including swap.
• Prints a full report to the Experts log on start - handy on a VPS.
• Separate calculation library with a self-test indicator (30 checks).

How It Works

• Margin level = equity / margin * 100.
• Target equity for a level L = L / 100 * margin (in money mode L is used as money directly). Distance = equity - target equity.
• Point value of a position = tick value * point / tick size, scaled by the volume. Trade functions (OrderCalcProfit, OrderCalcMargin) are not available in indicators, so the panel does not use them.
• Points to a level = distance in money / point value of the netted book. For a fully hedged book a move in points is not defined, so the panel shows "n/a".
• The panel is refreshed by timer, not by ticks, so it keeps updating on quiet symbols.

Input Parameters

Panel

• InpCorner (default: upper left) - panel corner.
• InpX / InpY (default: 12 / 20) - offset from the corner, pixels.
• InpFontSize (default: 9) - font size.
• InpTextColor, InpOkColor, InpWarnColor, InpDangerColor - text and status colors.
• InpShowBackground (default: true), InpBgColor, InpBorderColor - panel background.
• InpRefreshSeconds (default: 1) - refresh interval, seconds.

• InpPriceMove1 (default: 1.0) - scenario 1: adverse price move, %.
• InpPriceMove2 (default: 3.0) - scenario 2: adverse price move, %.
• InpEquityShock (default: 5.0) - scenario 3: equity drop, %.

Positions

• InpShowPositions (default: true) - show the positions table.
• InpMaxPositions (default: 8) - maximum rows in the table.

Installation

1. In MetaTrader 5 open File > Open Data Folder.
2. Create the folder MQL5/Indicators/MarginCallRadar/ and copy all three files into it: MarginCallRadar.mq5, RadarCore.mqh and MarginCallRadarTests.mq5. The files include RadarCore.mqh from their own folder, so they must stay together.
3. Open MarginCallRadar.mq5 and MarginCallRadarTests.mq5 in MetaEditor and compile them (F7), then refresh the Navigator.

Usage

Drag Margin Call Radar onto any chart: any symbol and timeframe will do. The panel appears in the chosen corner and covers the whole account, not only the chart symbol. To check the calculations, attach the MarginCallRadarTests indicator to any chart: it prints "RadarCore: all checks passed" to the Experts log and shows the result in the chart comment.

Example

Demo account, balance 100 000 USD, one position EURUSD buy 0.01:

Margin level 890459.66 %
To margin call 99993.00 USD (99.99 % of equity, 9999300 pts)
To stop out 99995.25 USD (100.00 % of equity, 9999525 pts)
Shock prices -1.0 % (11.23 USD) -> level 890359.69 %
Shock prices -3.0 % (33.68 USD) -> level 890159.76 %
Shock equity -5.0 % (4999.93 USD) -> level 845936.68 %

Manual check: 0.01 lot EURUSD = 0.01 USD per point, 1% of 1.1230 = 1123 points = 11.23 USD.

Notes

• Scenarios are estimates: a real gap, swap, commission or a change of margin requirements by the broker can make the result different.
• Please test on a demo account first.
