What is a Micro Lot in Forex? A Complete Guide for Thailand Traders in 2026

What Exactly is a Micro Lot?

A micro lot is the smallest standard lot size offered by most forex brokers. One micro lot equals 1,000 units of the base currency. If you are trading EUR/USD, one micro lot controls 1,000 euros. For a Thailand trader depositing in THB, this means your position size is manageable and your risk per trade is small.

How Does a Micro Lot Work in Practice?

When you open a trade of 1 micro lot, each pip movement is worth approximately $0.10 USD. At an exchange rate of 35 THB/USD, that is about 3.50 THB per pip. This allows you to trade with a small account—say 5,000 THB—and still control your risk effectively. For example, if you set a stop loss of 20 pips, your maximum loss is only 70 THB per trade.

Why Thailand Traders Use Micro Lots

Thailand traders often start with small capital due to lower average incomes compared to Western countries. Micro lots enable you to participate in the forex market with as little as 500 THB deposited via PromptPay. Experienced traders also use micro lots to fine-tune their strategies, test new pairs, or scale into positions gradually without overexposing their account.

Micro Lot vs Mini Lot vs Standard Lot

One standard lot = 100,000 units (approx. 3,500,000 THB). One mini lot = 10,000 units (approx. 350,000 THB). One micro lot = 1,000 units (approx. 35,000 THB). The smaller the lot size, the lower the margin requirement and the smaller the pip value. For Thailand traders, micro lots are the most accessible way to start trading without risking large sums of money.

For Thailand traders, micro lots are especially relevant because of local payment methods and the regulatory environment. You can deposit funds using PromptPay, Bank Transfer, or Skrill with most brokers. A PromptPay deposit of just 500 THB is enough to open a micro lot trade. Many brokers also accept THB directly, so you avoid conversion fees. SEC Thailand does not directly regulate forex brokers, but it oversees investor protection. Therefore, Thailand traders should choose brokers regulated by top-tier authorities like FCA, ASIC, or CySEC. Using micro lots allows you to trade with a low capital base while still adhering to sound risk management principles—keeping your risk per trade to 1-2% of your account balance.

1. Choose a broker that supports micro lots
   Look for brokers offering micro lot accounts (0.01 lot) and accepting PromptPay or THB deposits. Examples include XM, Exness, and IC Markets.
2. Deposit via PromptPay
   Deposit as little as 500 THB using PromptPay. The funds usually arrive instantly, allowing you to start trading immediately.
3. Set your position size to 0.01 lot
   In your trading platform, select 0.01 lot size. This equals one micro lot (1,000 units).
4. Calculate your risk in THB
   Determine your stop loss in pips. Multiply by 3.50 THB per pip to know your maximum loss. For example, a 20-pip stop = 70 THB risk.
5. Place your trade
   Enter the trade with your predefined stop loss and take profit. Monitor your position and adjust as needed.

Micro Lot vs Mini Lot for Thailand traders
A micro lot (0.01 lot) is 1,000 units with a pip value of 3.50 THB. A mini lot (0.10 lot) is 10,000 units with a pip value of 35 THB. If you have a 5,000 THB account, a mini lot trade with a 20-pip stop would risk 700 THB—14% of your account, which is too high. Micro lots allow you to stay within the recommended 1-2% risk per trade. Therefore, micro lots are better for small accounts, while mini lots suit traders with at least 50,000 THB in capital.

When you trade a micro lot, you are controlling 1,000 units of the base currency. For example, if you buy 1 micro lot of USD/THB at 35.00, you are buying 1,000 USD and selling 35,000 THB. Your broker requires a margin—typically 1% of the position size, or about 350 THB at 1:100 leverage. Each pip movement in USD/THB is worth 0.10 USD, or 3.50 THB. This means a 50-pip move results in a 175 THB profit or loss. Micro lots give you fine-grained control over your risk, allowing you to trade with a small account while still participating in the global forex market.

Example 1: Thailand trader with 5,000 THB account
You deposit 5,000 THB via PromptPay. You decide to trade 1 micro lot (0.01 lot) of EUR/USD with a 20-pip stop loss. Pip value = 3.50 THB. Maximum loss = 20 pips x 3.50 THB = 70 THB, which is 1.4% of your account. This is well within safe risk limits.

Example 2: Scaling up
After a month of profitable trading, your account grows to 10,000 THB. You now trade 2 micro lots (0.02 lot) with the same 20-pip stop. Risk = 140 THB, still only 1.4% of your account. This gradual scaling helps you grow while keeping risk in check.

Regulatory context for Thailand traders: The Securities and Exchange Commission (SEC) Thailand oversees capital markets and investor protection but does not directly regulate forex brokers. Instead, most forex brokers operating in Thailand are regulated by international bodies like the FCA (UK), ASIC (Australia), or CySEC (Cyprus). Thailand traders should always verify a broker's license and avoid unregulated entities. Using micro lots does not change regulatory requirements, but it does help you trade more safely by limiting your exposure. Always choose a broker that offers segregated client accounts and negative balance protection.

• Start small: Begin with a micro lot account and a deposit of 1,000-2,000 THB. This keeps your risk minimal while you learn.
• Use a stop loss: Always set a stop loss in pips. For a micro lot, a 20-pip stop equals only 70 THB—affordable even for small accounts.
• Scale up gradually: Once you are consistently profitable, increase your lot size to mini lots (0.10 lot) only after your account grows.
• Leverage wisely: With micro lots, you can use 1:100 leverage without overexposing your account. Avoid high leverage like 1:500.
• Track your trades: Keep a trading journal in THB to monitor your risk, profit, and loss. This helps refine your strategy over time.

Summary and next steps for Thailand traders: Micro lots are the ideal starting point for Thailand traders entering the forex market. They allow you to trade with low capital, manage risk precisely, and build experience without large drawdowns. To get started, choose a regulated broker that accepts PromptPay deposits, open a micro lot account, and practice with a demo first. Once you are comfortable, deposit as little as 500 THB and begin trading real micro lots. Remember to always use stop losses, track your performance in THB, and never risk more than 1-2% of your account per trade. Ready to start?
