# How is GTLot Calculated?

Updated 2 weeks ago

1. To calculate the volume in GTLot for both Fiat and Crypto currency pairs we use the formula:

Volume in USD = Lot x Contract Size x Base Currency to USD Price
Using BTCUSD as an example:
If BTCUSD having 1 lot, base currency BTC, Contract size 1 and base currency price to USD 40,000.
Volume in USD= Lot * Contract Size * Base Currency to USD Price
Volume in USD=1*1*40000=40000
Then:
GTLot=Volume in USD/100000
GTLot=40000/100000=0.4

2. To calculate the volume in GTLot for Stocks, Indices, Spot Metals, Energies, and other non-currency instruments we use the formula:

USD Volume Calculation = Lot X Contract Size x Price x Base Currency to USD Price
Using the stock of Apple (#AAPL) as an example:
If #AAPL having 1 lot, base currency USD, Contract size 100, current price 2000 and base currency price to USD 1 (USDUSD)
Volume in USD= Lot * Contract Size * Price * Base Currency to USD Price
Volume in USD=1*100*2000*1=200000
Then:
GTLot=Volume in USD/100000
GTLot=200000/100000=2
