What is a Lot?

Spot Forex is traded in lots. The standard size for a lot is $100,000. There is also a mini lot size and that is $10,000. As you already know, currencies are measured in pips, which is the smallest increment of that currency. To take advantage of these tiny increments, you need to trade large amounts of a particular currency in order to see any significant profit or loss.

Let’s assume we will be using a $100,000 lot size. We will now recalculate some examples to see how it affects the pip value.

USD/JPY at an exchange rate of 119.90
(.01 / 119.80) x $100,000 = $8.34 per pip

USD/CHF at an exchange rate of 1.4555
(.0001 / 1.4555) x $100,000 = $6.87 per pip

In cases where the US Dollar is not quoted first, the formula is slightly different.

EUR/USD at an exchange rate of 1.1930
(.0001 / 1.1930) X EUR 100,000 = EUR 8.38 x 1.1930 = $9.99734 rounded up will be $10 per pip

GBP/USD at an exchange rate or 1.8040
(.0001 / 1.8040) x GBP 100,000 = 5.54 x 1.8040 = 9.99416 rounded up will be $10 per pip.

Your broker may have a different convention for calculating pip value relative to lot size but whichever way they do it, they'll be able to tell you what the pip value is for the currency you are trading is at the particular time. As the market moves, so will the pip value depending on what currency you are currently trading.
