Crypto QuickCalc - PnL & Fees

About

Crypto QuickCalc is a focused calculation tool for crypto traders who want to understand the key numbers before placing an order.
Instead of switching between spreadsheets, exchange pages, and manual formulas, Crypto QuickCalc helps you quickly estimate trading fees, net profit and loss, liquidation distance, position size, target exit price, trade plan risk/reward, and DCA average cost in one lightweight extension.
