Show (sym show) 🔍

What it Does

Shows a short card for a symbol: last quote (Bid/Ask/Time) and volume limits (min/step/max). Best-effort makes the symbol visible in the terminal before requests.

Method Signatures

// Ensures that a symbol is visible in terminal UI (best-effort).
public Task EnsureSymbolVisibleAsync(
    string symbol,
    TimeSpan? maxWait = null,
    CancellationToken cancellationToken = default);

// Returns last tick (Bid/Ask/Time) for a symbol.
public Task<TickData> SymbolInfoTickAsync(
    string symbol,
    DateTime? deadline = null,
    CancellationToken cancellationToken = default);

// Returns (min, step, max) volume constraints for a symbol.
public Task<(double min, double step, double max)> GetVolumeConstraintsAsync(
    string symbol,
    DateTime? deadline = null,
    CancellationToken cancellationToken = default);

Code Reference 🧩

// --- Quick use ---
// Get quote + volume limits for a symbol.
var sym = symbol ?? GetOptions().DefaultSymbol;

// Ensure symbol is visible (best-effort)
await _mt5Account.EnsureSymbolVisibleAsync(sym);

// Quote
var tick = await _mt5Account.SymbolInfoTickAsync(sym);

// Volume limits
var (min, step, max) = await _mt5Account.GetVolumeConstraintsAsync(sym);

// Print
Console.WriteLine($"{sym}: Bid={tick.Bid} Ask={tick.Ask} Time={tick.Time}");
Console.WriteLine($"Volume: min={min} step={step} max={max}");

// --- JSON output example ---
// Console.WriteLine(ToJson(new {
//     symbol = sym,
//     quote = tick,
//     volume = new { min, step, max }
// }));

How to Use 🛠️

CLI

dotnet run -- sym show -p demo
dotnet run -- sym show -p demo -s EURUSD
dotnet run -- sym show -p demo -s XAUUSD --output json

When to Use ❓

• Quick diagnostics — quickly check the quotation and volume limits.
• Before placing orders — verify the available volumes and that the symbol is visible.
• Environment check — to make sure that the server returns the correct data on the tool.
