A pip in forex is equivalent to one-hundredth of one percent, or 0.01%, of a single unit. Moving from 1.0003 to 1.0004 would constitute a one-pip change.

To put it mathematically: 1 Pip = (1/100) * 0.01

How to Calculate Lot Size – Forex Lot Size Calculator

Let’s say that you had a trading account with the balance of $10,000, and you decided to risk 1% of your account on a single trade, meaning that you are willing to lose a maximum of $100 on any given trade.

You want to trade the EUR/USD currency pair, which typically moves in pips. A pip in forex represents the smallest increment for most currency pairs.

The current exchange rate is 1.2000, and you believe it will go up. You’ve chosen a starting point at 1.2050 and set a stop-loss order at 1.2000 to limit your potential loss.

To calculate your forex lot size, you need to consider both the number of pips you’re risking and the value of each pip. The difference between your entry and stop-loss price is 50 pips.

Now that you know the standard lot size for EUR/USD in forex is 100,000, and each pip in a standard lot size is worth $10, you can calculate your lot size as follows:

Lot size = (Maximum Risk per Trade) / (Pips at Risk) * (Value of Each Pip) Lot size = ($100) / (50 pips) * ($10) Lot size = 2 mini lots

So, you have concluded that you should trade 2 mini lots or, in other words, $20,000 in forex instead of a standard lot to stay within your 1% risk tolerance.

This way, even if the trade goes against you, and you get stopped out at 1.2000, you’ll only lose $100.

Leverage and Lot Size

Let’s say you are starting with $1000 in your trading account.

You already know what a standard lot in forex is, and you know it can be very intimidating for someone with a $1000 balance.

This is where forex lot size and leverage comes into play. Forex brokers offer various leverage ratios that allow you to control larger amounts than your account balance.

Leverage multiplies the lot size. Let’s say, with a 100:1 leverage, Alex’s $1000 account acts as a $100,000 account, which is equivalent to a standard lot in forex.

This is the logic behind forex lot size and leverage.

How Profit and Loss are Determined Based on Lot Size and Price Movements

If you buy a currency pair, go long, and its price increases, voilà, you make a profit!

The profit is calculated based on the number of pips that has moved in your favor and the forex lot size you are trading.

Profit = (Number of Pips) x (Pip Value) x (Number of Lots)

For example you bought 1 standard lot of EUR/USD pair at 1.2000 and sold it at 1.2050, you’d have 50 pips profit. If the pip value is $10 your profit would be:

Profit = 50 pips x $10 x 1 lot = $500

If you buy a currency pair and its price decreases, or if you sell a currency pair (go short) and its price increases, you’ll face with a loss. The formula for calculating the loss is the same as for profit. For example, if you bought 1 standard lot of EUR/USD at 1.2000 and sold it at 1.1950, using the same pip value, you’d loose 50 pips.
