MT4 Lot Size Calculator

Lot size for MetaTrader 4: forex, US30, NAS100, stocks, gold, oil, and crypto CFDs. Risk percent and stop in, lots to open out.

Built for MetaTrader 4 New Order. Same formula on every symbol: risk money divided by stop distance times the value of 1.00 lot per pip or point. Check Tick value in Specification if your broker’s contract is not the preset.

Lots to open (MT4)0.50
Mini lots (0.10)5
Micro lots (0.01)50
Contract units50,000
Value / 1.00 lot / 1 pip10 USD
Risk if stop hits100 USD

Presets are common CFD specs. If MT4 Specification shows another Tick value, type that number. Brokers round lots (often 0.01). Spread can take the stop before your distance.

What is a lot in MT4?

A lot is the unit MetaTrader 4 uses for trade size. On forex, 1.00 standard lot is 100,000 units of the base currency, 0.10 is a mini lot (10,000) and 0.01 is a micro lot (1,000).

On index, stock, commodity and crypto CFDs the broker sets the contract: stock and crypto CFDs are usually 1 share or 1 coin per lot, gold is usually 100 ounces, and indices are set as an amount per index point.

Pips, points and value per lot

A pip is 0.0001 on most pairs and 0.01 on JPY pairs, so 1.00 lot pays 10 units of the quote currency per pip (1,000 yen on JPY pairs). On EURUSD that is $10 per pip on 1.00 lot and $0.10 on 0.01 lot.

CFDs are sized in points. The value of 1.00 lot per point is the Tick value in MT4 Specification; this calculator ships common presets you can overwrite.

How to use the MT4 lot size calculator

  1. Pick the market tab and symbol, then enter your account size and currency.
  2. Enter the risk percent and the stop loss in pips (forex) or points (CFDs).
  3. Type the Lots to open figure in MT4 New Order, rounded down to 0.01.

Common lot size mistakes

  • Using the same lot size on every market. 1.00 lot of gold, NAS100 and EURUSD carry very different money per move.
  • Assuming every pair pays $10 per pip. Only pairs quoted in USD do on a USD account.
  • Sizing first and placing the stop to fit. Place the stop where the idea is wrong, then size.

Educational content, not investment advice. Trading leveraged products such as CFDs and forex carries a high risk of losing money.

Lots = risk money ÷ (stop distance × value of 1.00 lot per pip or point). A wider stop or a richer contract means fewer lots for the same risk.
