PnL is the difference between the current market value of an asset and its original purchase price. If an asset’s market value increases, then the PnL is positive. If the market value decreases, then the PnL is negative.

The PnL calculation for an individual position is straightforward. For example, if you bought 1 BTC at $5,000 and it’s now worth $6,000, your PnL is $1,000.

To calculate your overall PnL on Binance, you need to take into account all of the positions that you have open. To do this, you first need to calculate the PnL for each position.

Then, you need to sum up all of the individual PnLs to get your overall PnL.

For example, let’s say that you have three positions open on Binance:

1 BTC at $5,000

2 ETH at $200

1 LTC at $50

To calculate your overall PnL, you would first calculate the PnL for each position individually. For the BTC position, your PnL would be ($6,000 – $5,000) = $1,000. For the ETH position, your PnL would be ($400 – $200) = $200. For the LTC position, your PNl would be ($100 – $50) = $50.

Then, you would sum up all of the individual PNLs to get your overall PNL. In this case, your overall PNL would be $1,250.

Your overall PNL will fluctuate as the prices of the assets that you are holding change. If the prices of all of the assets that you are holding increase by 10%, then your overall PNL will increase by 10%.

Similarly, if the prices of all of the assets that you are holding decrease by 10%, then your overall PNL will decrease by 10%.

The main reason why people care about their overall PNL is because it directly impacts their account balance. Your account balance is equal to your initial deposit plus or minus your overall PNL.

So, if your initial deposit was $10,000 and your current overall PNL is $1,000, then your account balance would be $11,000. On the other hand, if your initial deposit was $10,000 and your current overall PNL is -$1,000, then your account balance would be $9.
