# Calculations
1. **Average entry price calculation for positions**
| Scenario | Sub-scenario | Average Entry Price |
|---|
| New position opened | | AvgEntryPrice = TradePrice |
| New trade for an existing position | Side changed, i.e. long became short or short became long | AvgEntryPrice = TradePrice |
| Size reduced, i.e. long reduces in size but remains long, or, short reduces in size but remains short | AvgEntryPrice = LastAvgEntryPrice |
| Size increased, i.e. long increase in size but remains long, or, short increases in size but remains short | AvgEntryPrice = (PreviousSize * LastAvgEntryPrice + TradedSize * TradePrice) / NewSize |
**P.S.: Fees is not considered while calculating average entry price of positions, total fees for a position is shown separately**
2. **Realised Profit and Loss calculation for trades**
| Scenario | Sub-scenario | Realised Pnl |
| ---------------------------------- | ----------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------ |
| New position opened | | Realised Pnl = 0 |
| New trade for an existing position | Side changed, i.e. long became short or short became long | Realised Pnl = Pnl for the side which was closed
Unrealised Pnl for position is set to 0
|
| | Size reduced, i.e. long reduces in size but remains long, or, short reduces in size but remains short | Realised Pnl = (InitialSize - FinalSize) \* (TradePrice - LastAvgEntryPrice) |
| | Size increased, i.e. long increases in size but remains long, or, short increases in size but remains short | Realised Pnl = 0 |
3. **Realised funding calculation for trades**
| Scenario | Sub-scenario | Realised funding |
| ---------------------------------- | ----------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------- |
| New position opened | | Realised funding = 0 |
| New trade for an existing position | Side changed, i.e. long became short or short became long | Realised funding = Funding accumulated since the last trade
Unrealised funding for corresponding position is set to 0
|
| | Size reduced, i.e. long reduces in size but remains long, or, short reduces in size but remains short | Realised funding = Funding accumulated since last trade
Unrealised funding for corresponding position is set to 0
|
| | Size increased, i.e. long increases in size but remains long, or, short increases in size but remains short | Realised funding = Funding accumulated since last trade
Unrealised funding for corresponding position is set to 0
|
4. **Fees calculation for orders**\
The fee displayed for orders covers the total fee incurred from placing the order to creating the position (There is a delay between aforementioned events due to delayed order mechanism of Synthetix)
| Type of order | Fees calculation |
| -------------- | ---------------------------------------------------- |
| Standard order | Fees = keeper fee + execution fee |
| Limit order | Fees = limit order fees + keeper fee + execution fee |
5. **Unrealised funding calculation for positions**
Funding shown in positions tab is the unrealised funding accrued for the position since the last trade placed by the user. \
\
P.S.: There is a cron which updates the unrealised funding for a position every 3 minutes, so the unrealised funding shown is not always accurate.
6. **Realised Pnl calculation for liquidations**
Realised Pnl for a liquidation can be seen in the **`History`** tab. A new trade is created with side field set to **Liquidation.** Realised pnl for a liquidation trade is set to the total margin present in the market when the position was liquidated.
