Entry Price and PnL

Your Entry Price is the baseline for all PnL calculations. TxFlow tracks two types of PnL:

• Unrealized PnL — Floating profit/loss based on current Mark Price. Changes in real time.

• Realized PnL — Locked-in profit/loss from closed or reduced positions. Cannot change.

Entry Price

Entry Price is the volume-weighted average price at which you opened or added to your position.

How It's Calculated:

Entry Price = ∑(Fill Price × Fill Size) ÷ Total Position Size

Action	Effect on Entry Price	Example
Open position	Set to fill price	Buy 1 BTC @ 50,000 → Entry=50,000
Add to position (same direction)	Recalculate weighted average	Hold 1 BTC @ $50,000, buy 1 BTC @ $51,000 → Entry = $50,500
Reduce position (partial close)	No change	Hold 2 BTC @ $50,500, sell 1 BTC → Entry stays $50,500
Flip position (reverse direction)	Recalculate for new position	Hold 1 BTC long @ $50,000, sell 3 BTC → Close long, open 2 BTC short @ new entry

Entry price resets to 0 when the position is fully closed.

Unrealized PnL

Unrealized PnL updates in real time with the Mark Price.

Long positions:

Unrealized PnL = (Mark Price − Entry Price) × Position

Short positions:

Unrealized PnL = (Entry Price − Mark Price) × Position

Realized (Closed) PnL

Realized PnL is locked in when you fully or partially close a position.

Long position:

Realized PnL = (Exit Price − Entry Price) × Closed Size

Short position:

Realized PnL = (Entry Price − Exit Price) × Closed Size

Net Closed PnL (after fees):

Net Closed PnL = Gross PnL − Trading Fees − Funding Fees Paid

Realized PnL is immediately credited to or debited from your USDC balance upon settlement.

Return on Equity (ROE)

ROE measures your profit relative to the initial margin used:

ROE = PnL ÷ Initial Margin  Fees × 100%
