What lot size should a beginner use?

Beginners should start with micro lots (0.01). This allows you to trade with real money while limiting risk to cents per pip, giving you room to learn without significant losses.

How many lots can I trade with $100?

With 1:100 leverage, a $100 account can theoretically control up to $10,000 (0.1 standard lot). However, for proper risk management, you should trade no more than 0.01 lots (1 micro lot) per trade.

What's the difference between lot and volume?

In forex, "lot" and "volume" are often used interchangeably. Volume in MT4/MT5 represents lot size — a volume of 1.0 means 1 standard lot (100,000 units).

Can I trade fractional lots?

Yes, most brokers allow trading in fractional lots (e.g., 0.15 or 0.37). This gives you precise control over position sizing to match your exact risk parameters.

Does lot size affect spread?

No, the spread remains the same regardless of lot size. However, the dollar COST of the spread increases with larger lots since each pip is worth more.
