What is Lot Size in Forex? A Complete Guide for Bangladesh Traders (2026)

What is a Lot in Forex?

A lot is a standardized unit of trade size. The standard lot equals 100,000 units of the base currency. However, most retail traders, especially in Bangladesh, use smaller lot sizes to keep risk manageable.

Types of Lot Sizes

• Standard Lot: 100,000 units — not recommended for beginners with small accounts.
• Mini Lot: 10,000 units — suitable for accounts with 50,000 BDT or more.
• Micro Lot: 1,000 units — ideal for traders starting with 5,000–10,000 BDT via bKash.
• Nano Lot: 100 units — offered by some brokers for ultra-low risk.

Lot Size and Pip Value in BDT

For a standard lot, one pip in EUR/USD is worth $10 (about 1,100 BDT). For a micro lot, one pip is worth $0.10 (about 11 BDT). This makes micro lots perfect for Bangladesh traders who want to control risk with small deposits.

How Lot Size Affects Margin

Margin is the amount required to open a trade. With 1:500 leverage, a micro lot of EUR/USD requires about $2 margin (220 BDT). A mini lot requires $20 (2,200 BDT). Always use a margin calculator before trading.

For Bangladesh traders, lot size is especially important because most start with small deposits via bKash or Nagad — often 5,000 to 20,000 BDT. Using micro lots (0.01) allows you to trade with low risk and learn without blowing your account. Mobile-first traders often use apps that display lot sizes in simple terms. Brokers popular in Bangladesh offer micro and nano lots to accommodate low deposits. USDT TRC20 deposits also allow you to fund accounts with as little as $10 (1,100 BDT). Always match your lot size to your account balance — never risk more than 1-2% per trade.

1. Understand the lot types: Learn the difference between standard, mini, micro, and nano lots. For Bangladesh traders, micro lots (0.01) are best for small accounts.
2. Choose your deposit method: Use bKash, Nagad, or USDT TRC20 to fund your account. Minimum deposits are often as low as 1,000 BDT.
3. Calculate pip value in BDT: For a micro lot, 1 pip = $0.10 (11 BDT). For a mini lot, 1 pip = $1 (110 BDT). Adjust based on your lot size.
4. Set your risk per trade: Decide to risk 1-2% of your account. For a 10,000 BDT account, that’s 100-200 BDT per trade. Use micro lots to stay within this limit.

Lot size is often confused with contract size, but they are the same. In forex, a standard lot is always 100,000 units. However, some brokers offer fractional lots like 0.001 (nano). For Bangladesh traders, the key comparison is between micro and mini lots: micro lots allow smaller risk and are better for beginners, while mini lots suit larger accounts. Always choose a broker that offers both options.

Lot size works by defining the volume of your trade. When you open a buy order for 0.01 lots of EUR/USD, you are buying 1,000 euros. The broker requires a margin, which is a fraction of the total value. For a Bangladesh trader with 1:500 leverage, the margin for a micro lot is about $2 (220 BDT). The pip value changes with lot size: 1 pip for a micro lot is $0.10 (11 BDT), for a mini lot it is $1 (110 BDT). This helps you calculate potential profit or loss in BDT.

Example 1: You deposit 10,000 BDT via bKash. You trade 0.01 lots (micro) of EUR/USD. One pip move = 11 BDT. If price moves 50 pips in your favor, you gain 550 BDT (5.5% of account).
Example 2: You deposit 50,000 BDT via USDT TRC20. You trade 0.10 lots (mini). One pip = 110 BDT. A 30-pip loss would lose 3,300 BDT (6.6% of account). Adjust lot size to keep risk below 2% per trade.

The Bangladesh Securities and Exchange Commission (BSEC) does not directly regulate forex lot sizes, but it oversees brokers operating in the country. Traders should ensure their broker is regulated by a reputable authority like the FCA (UK), CySEC (Cyprus), or ASIC (Australia). BSEC advises caution when dealing with unregulated offshore brokers. Always check if the broker is licensed and offers transparent lot size options. For Bangladesh traders, using a regulated broker ensures fair pricing and proper risk management.

• Start with micro lots: With a 5,000 BDT deposit, micro lots (0.01) keep your risk low and allow you to learn.
• Use a margin calculator: Always check margin before trading — many brokers offer this in their mobile apps.
• Adjust lot size for volatility: During news events, reduce lot size to avoid large swings.
• Never risk more than 2%: For a 10,000 BDT account, max loss per trade should be 200 BDT.
• Practice with a demo account: Most brokers accepting bKash offer demo accounts to test lot sizes risk-free.

Understanding lot size is the first step to managing risk in forex trading. For Bangladesh traders, micro lots are the safest choice when starting with small deposits via bKash, Nagad, or USDT TRC20. Always calculate pip value in BDT, use proper leverage, and never risk more than 2% per trade. Ready to start?
