Symbol Information
The Symbol Information retrieves detailed, real-time properties of a specific trading instrument such as EURUSD, BTCUSD, or XAUUSD.
Symbol Information (Market Details)
Symbol Information tells you how a symbol trades, what it costs to trade, and what limits or rules apply before you place, modify, or manage positions.
This is one of the most important building blocks for risk control, position sizing, and execution accuracy.
When to Use This
Use Symbol Information when you need to:
- Confirm spread, commission, and swap costs
- Calculate pip value, tick value, or lot size
- Check minimum / maximum trade size
- Verify whether a symbol is currently tradable
- Understand leverage tiers and exposure limits
- Adjust strategy per asset (Forex vs Crypto vs Metals)
- Validate execution before entry, scaling, or exits

What Information You Get
Pricing & Market Data
- Bid / Ask Current buy and sell prices.
- Spread The cost of entering a trade (Ask − Bid). → Wider spreads = higher entry cost.
- Digits / TickSize / PipSize Price precision and smallest price movement. → Important for stop loss, take profit, and trailing stops.
Position Sizing & Volume Rules
- VolumeInUnitsMin Smallest allowed trade size.
- VolumeInUnitsMax Maximum allowed trade size.
- VolumeInUnitsStep How much volume can increase or decrease per step.
- LotSize Units per standard lot (e.g., 100 000 for Forex).
Why this matters:
Prevents invalid orders and ensures correct scaling.
Profit, Loss & Value Calculations
- PipValue Monetary value of one pip per lot.
- TickValue Monetary value of one tick movement.
- UnrealizedNetProfit / UnrealizedGrossProfit Current floating PnL for all open positions on this symbol.
Used for:
Risk per trade, reward calculation, breakeven logic.
Asset Structure
- BaseAsset The asset being traded (e.g., EUR in EURUSD).
- QuoteAsset The currency used for pricing (e.g., USD in EURUSD).
Used for:
PnL conversion, exposure analysis, correlation logic.
Trading Costs
- Commission Cost per trade or per volume.
- CommissionType How commission is calculated (per lot, per trade, etc).
- MinCommission / MinCommissionType Minimum fee applied even on small trades.
Why this matters:
High commissions can invalidate scalping or high-frequency strategies.
Trading Availability & Mode
- IsTradingEnabled Whether the symbol can currently be traded.
- TradingMode Normal, close-only, disabled, etc.
Used to prevent:
Rejected trades or unexpected execution failures.
Swap & Holding Costs
- SwapLong / SwapShort Overnight holding cost for buy and sell positions.
- SwapCalculationType How swaps are calculated.
- Swap3DaysRollover Triple swap day (usually Wednesday).
Critical for:
Swing trades, position trades, carry strategies.
Dynamic Leverage (Advanced Risk Control)
- DynamicLeverage Leverage tiers that change based on volume size.
Example:
- Small volume → high leverage
- Large volume → reduced leverage
Why this matters:
Scaling positions can suddenly increase margin usage.
Custom Symbols
- IsCustom Indicates broker-specific or synthetic instruments.
Use caution:
Custom symbols may have unique rules or risks.
Always retrieve Symbol Information before trading a new instrument.
Every symbol has its own rules — never assume.
How Symbol Info Influences Trading Decisions
Entry Decisions
- Avoid trading when spread is unusually high
- Adjust stop size using pip value
- Validate minimum volume before sending order
Exit & Protection Logic
- Place stops using tick size precision
- Avoid disabling SL on high swap symbols
- Use pip value to set breakeven accurately
Risk & Safety Rules
- Block trades if IsTradingEnabled = false
- Reduce size if dynamic leverage drops
- Avoid holding overnight if swap is negative
Example:
Smart Entry Logic
Open 1 lot on EURUSD **only if**
spread < 1.5 pips,
trading is enabled,
and pip value supports 1% risk.
Scaling Safely
Add volume step-by-step,
but stop scaling if leverage tier changes
or margin requirement increases.
Holding Trade Overnight
Check swap cost before holding XAUUSD overnight.
If swap is strongly negative, close before rollover.
