How to Use TradingCalc:

Precision is the foundation of institutional trading. Follow this structured workflow to ensure your risk is strictly managed on every setup:

Account Setup: Select your Account Currency (USD, EUR, GBP, etc.) and enter your current Balance. This is the capital the engine uses to calculate percentage-based risk.
Define Risk: Choose between risking a Percentage of your equity (e.g., 1%) or a Fixed Currency amount. Professionals rarely exceed 2% per trade.
Asset Selection: Choose your pair from the instrument list. TradingCalc automatically adjusts its logic for Forex, Crypto, Indices, and Commodities.
Input Parameters: Enter your Entry Price and Stop Loss (SL); pips and percentages calculate instantly and you can also define your Take Profit (TP) to see your projected Risk-to-Reward ratio.
Execution: Hit "Calculate" to see your exact Lot Size requirements, Dual-Mode leverage suggestions to optimize your margin usage, position size, notional value, margin estimates, and liquidation analytics.
Export: Export the HD result card or share directly for journaling or reporting.

How to Calculate Lot Size in Forex?

The TradingCalc engine automates a complex multi-step process to protect your capital. The mathematical structure for determining position size is:

Lot Size = Risk Amount / (Stop Loss Pips \times Pip Value per Lot)

Our engine handles three critical layers of this calculation instantly:

Pip Distance: The difference between your Entry and SL, adjusted for the asset's specific decimal precision (e.g., 5-digit for G10, 3-digit for Yen).
Pip Value Conversion: If your account currency differs from the quote currency (e.g., USD account trading EURGBP), the engine performs a real-time conversion.
Asset Scaling: Automatically switching between 100,000 unit scales (Forex) and direct unit scales (Crypto/Shares).

Types of Lots in Forex

Understanding lot types is essential for managing leverage and margin effectively across different account sizes.

Lot Type	Volume (Lots)	Units (Base Currency)	Est. Pip Value (USD Pairs)
Standard Lot	1.00	100,000	$10.00 / Pip
Mini Lot	0.10	10,000	$1.00 / Pip
Micro Lot	0.01	1,000	$0.10 / Pip
Nano Lot	0.001	100	$0.01 / Pip

Note: Pip values vary based on the quote currency and current exchange rates. The values above are typical for pairs where USD is the quote currency (e.g., EURUSD).
