What is the relationship between Forex lots and pips?
Lot and pip help traders calculate profit/loss when trading on currency markets.
Example:
Trader opens a position of 2 lots EURUSD. The currency pair’s price moves 2 pips in favor, the trader’s profit: 2 lots * 100,000 euros * 0.0001 (value of 1 pip) * 2 (number of pips) = 20 EUR.
What is the relationship between Lot and Leverage?
If a trader opens an account with 1:200 leverage, they can trade the equivalent of an account of 1000$ x 200 = 200,000$.
So a 1000$ account with 1:200 leverage, traders can trade up to 2 lots.
Leverage allows traders to trade larger volumes (or lots) than their actual capital.
Forex brokers often offer leverage from 1:1 (no leverage) up to 1:500 and even higher. Leverage regulations vary from country to country and from broker to broker.
How to calculate the value of 1 forex lot?

- Contract size: 100,000 = 1 standard lot
- Trading volume: 1000 base currency = 0.1 standard lot
- USD/CHF exchange rate: – 0.91070
- So, the lot value in USD = 100,000 * 0.01 = 1,000.
- Thus, the transaction value is 0.01 lot.
- Trader will buy 9,107 CHF and deposit 1,000 USD
1 forex lot for cross currency pair:
Lot value = contract size * trading volume * asset price / quoted currency price
For example, Trader buys GBP/CAD currency pair:
- Contract size: 100,000 VND
- Trading volume: 1000 base currency = 0.01 lot
- GBP/CAD exchange rate: 1.72608
- USD/CAD exchange rate:1.32972
- So, the lot value = 100 000 * 0.01 * 1.76028 / 1.32972 = 1 298.08 USD
