Average Price tracks your buys and sells and calculates the weighted average cost of your open position in real time.
Pick a coin and quote currency (USD or EUR), save each fill, and compare your average to the live market price for unrealized P&L. You can also add trading quantity with no price and no added cost basis.
What is this tool?
It stores buys and sells per coin and recomputes quantity, cost basis and average price after every trade.
Sells reduce the position at the current average (cost-basis method) so remaining coins keep a consistent average. Add quantity (trading) increases coins without adding cost basis.
Live market prices refresh about every minute from the PEPS Average Price catalog (Binance spot).
How to read the results
Average price is total remaining cost ÷ remaining quantity after chronological buys, sells and quantity adjustments.
Unrealized P&L compares market value to cost basis in the quote currency you selected.
Trade history lists each fill; delete a row to recalculate instantly.
