✅ Getting Individual Account Double Properties¶

Request: single double property from MT5 account. Fetch specific numeric properties like balance, equity, margin, profit, etc.

API Information:

SDK wrapper: MT5Account.AccountInfoDoubleAsync(...) (from NuGet package MetaRPC.MT5)
gRPC service: mt5_term_api.AccountInformation
Proto definition: AccountInfoDouble (defined in mt5-term-api-account-information.proto)

RPC¶

Service: mt5_term_api.AccountInformation
Method: AccountInfoDouble(AccountInfoDoubleRequest) → AccountInfoDoubleReply
Low‑level client (generated): AccountInformation.AccountInfoDouble(request, headers, deadline, cancellationToken)
SDK wrapper (your class):

namespace mt5_term_api
{
    public class MT5Account
    {
        public async Task<double> AccountInfoDoubleAsync(
            AccountInfoDoublePropertyType property,
            DateTime? deadline = null,
            CancellationToken cancellationToken = default);
    }
}

Request message:

AccountInfoDoubleRequest { property_id: AccountInfoDoublePropertyType }

Reply message:

AccountInfoDoubleReply { data: AccountInfoDoubleData } or { error: Error }

🔽 Input¶

Parameter	Type	Required	Description
`property`	`AccountInfoDoublePropertyType`	✅	Property to retrieve (see enum below)
`deadline`	`DateTime?`	❌	Absolute per‑call UTC deadline → converted to timeout
`cancellationToken`	`CancellationToken`	❌	Cooperative cancel for the call/retry loop

⬆️ Output — `AccountInfoDoubleData`¶

Field	Type	Description
`RequestedValue`	`double`	The requested property value

The method returns double directly (unwrapped from the proto message).

`ACCOUNT_MARGIN_SO_CALL`	7	Margin call level. Depending on the set ACCOUNT_MARGIN_SO_MODE is expressed in percents or in the deposit currency
`ACCOUNT_MARGIN_SO_SO`	8	Margin stop out level. Depending on the set ACCOUNT_MARGIN_SO_MODE is expressed in percents or in the deposit currency
`ACCOUNT_MARGIN_INITIAL`	9	Initial margin. The amount reserved on an account to cover the margin of all pending orders
`ACCOUNT_MARGIN_MAINTENANCE`	10	Maintenance margin. The minimum equity reserved on an account to cover the minimum amount of all open positions

`ACCOUNT_COMMISSION_BLOCKED`	13	The current blocked commission amount on an account

💬 Just the essentials¶

What it is. Single RPC returning one specific double property of the account.
Why you need it. When you only need one property (e.g., margin level before placing an order) instead of fetching the full account summary.
Performance. Lightweight call — ideal for frequent checks of specific properties.
Alternative. Use AccountSummaryAsync() if you need multiple properties at once.

🎯 Purpose¶

Use this method when you need to:

Check a single account property (margin, equity, profit, etc.) without fetching all account data.
Monitor specific properties frequently (e.g., margin level for risk management).
Verify free margin before placing trades.
Calculate margin requirements dynamically.

🧩 Notes & Tips¶

Prefer AccountSummaryAsync() if you need multiple properties — it's more efficient to fetch all data in one call.
Use short per‑call timeout (3–5s) with retries for margin checks before trading operations.
All MT5Account methods have built-in protection against transient gRPC errors with automatic reconnection.
For UI dashboards displaying multiple properties, use AccountSummaryAsync() instead.
The method returns double directly (not wrapped in a proto message) for convenience.

🔗 Usage Examples¶

1) Check margin level before placing order¶

// Ensure sufficient margin before trading
var marginLevel = await acct.AccountInfoDoubleAsync(
    AccountInfoDoublePropertyType.ACCOUNT_MARGIN_LEVEL,
    deadline: DateTime.UtcNow.AddSeconds(3));

if (marginLevel < 200.0)
{
    Console.WriteLine($"⚠️ Warning: Low margin level {marginLevel:F2}%");
    // Skip trading or reduce position size
}
else
{
    Console.WriteLine($"✅ Margin level OK: {marginLevel:F2}%");
}

2) Get current profit¶

// Monitor floating profit/loss
var profit = await acct.AccountInfoDoubleAsync(
    AccountInfoDoublePropertyType.ACCOUNT_PROFIT);
Console.WriteLine($"Current P/L: {profit:F2}");

3) Check free margin¶

// Verify free margin before opening position
var freeMargin = await acct.AccountInfoDoubleAsync(
    AccountInfoDoublePropertyType.ACCOUNT_MARGIN_FREE);

Console.WriteLine($"Free margin: {freeMargin:F2}");

if (freeMargin < 100.0)
{
    Console.WriteLine("⚠️ Insufficient free margin");
}

4) Monitor margin usage¶

// Fetch margin-related properties
var margin = await acct.AccountInfoDoubleAsync(
    AccountInfoDoublePropertyType.ACCOUNT_MARGIN);
var marginFree = await acct.AccountInfoDoubleAsync(
    AccountInfoDoublePropertyType.ACCOUNT_MARGIN_FREE);
var marginLevel = await acct.AccountInfoDoubleAsync(
    AccountInfoDoublePropertyType.ACCOUNT_MARGIN_LEVEL);

Console.WriteLine($"Margin:       {margin:F2}");
Console.WriteLine($"Free:         {marginFree:F2}");
Console.WriteLine($"Level:        {marginLevel:F2}%");

5) Compare equity vs balance¶

// Calculate floating P/L by comparing equity and balance
var balance = await acct.AccountInfoDoubleAsync(
    AccountInfoDoublePropertyType.ACCOUNT_BALANCE);
var equity = await acct.AccountInfoDoubleAsync(
    AccountInfoDoublePropertyType.ACCOUNT_EQUITY);

var floatingPL = equity - balance;
Console.WriteLine($"Balance:      {balance:F2}");
Console.WriteLine($"Equity:       {equity:F2}");
Console.WriteLine($"Floating P/L: {floatingPL:F2}");
