Looking out for margin requirements is crucial. If your equity level falls below 15% of the required margin, some or all of your current positions will be forcibly closed to prevent further losses—that is called a Stop Out. We will send you a notification known as a margin call when your equity level falls down to 25% of the overall margin. It will give you time to make an additional deposit or close some orders manually.

Octa Forex margin calculator helps you to determine the margin size you must maintain in your trading account to support an open position. You can also use it to calculate the pip value of a certain order or optimise your leverage. The calculator is an essential tool for every trader—it helps you prevent Stop Outs and manage your risks properly.

## How to calculate margin using the calculator

To determine the required margin size for a planned order, select the tab with the preferred trading platform: MetaTrader 4, MetaTrader 5, or OctaTrader. Choose the currency pair, your account's currency, leverage level, and trade volume. Finally, press the **Calculate** button. The margin will be calculated automatically using the specifications of the chosen trading platform. This number shows how much funds you need to open your order with the current leverage.

## How to use the calculator to optimise leverage

You can also use the Octa Forex margin calculator to adjust your leverage.

Choose the currency pair, your account's currency, leverage level, and trade volume. Finally, press the Calculate button. The margin will be calculated automatically using the specifications of the chosen trading platform. This number shows how much funds you need to open your order with the current leverage. If the calculated margin size for an order is larger than your available funds, try selecting a higher leverage ratio.

### Example: how to optimise leverage

Let us say you want to buy a standard lot of EURUSD using 1:100 leverage and have 600 USD in your account. According to the calculator, you need 1,064.54 USD to place the order. If you change your leverage to 1:200, the margin will be 532.27 USD. You can now place that order once you increase the leverage in your account settings.

## How to determine lot size with the calculator

You can use the calculator to choose the optimal lot size as well. Before placing an order, compare your available equity to the required margin and select your order size accordingly.

### Example: how to find the optimal lot size

For instance, you want to buy 10 lots of EURUSD with 1:500 leverage and have 1,500 USD in your account. According to the calculator, you need 2,141.88 USD to do that. Try changing the volume of your order—you can buy 7 lots for 1,499.05 USD with your available funds. However, there is also an option to deposit 641.88 USD more and buy 10 lots.

## How much is one pip in Forex?

A pip is the smallest unit of price change in Forex. Its meaning varies for different trading instruments:

- for 5-digit currency pairs—the 4th decimal (0.0001)
- for 3-digit currency pairs and XAGUSD—the 2nd decimal (0.01)
- for XAUUSD, XBRUSD, XTIUSD—the 1st decimal (0.1)
- for indices (exсept JPN225)—the 1st decimal (0.1)
- for JPN225—the 4th decimal (0.0001).

### Example: how to use pip value

Let us say you want to buy a standard lot of EURUSD, and the price is currently at 1.0762. The calculated pip value of this trade is 10 USD. That means that if the price falls to 1.0761, or one pip down, you will lose 10 USD. And if it grows back to 1.0762, or one pip up, you will make 10 USD.
