Open the toolSeed phrase backup sheet

Open the toolRead only, on purpose
Every tool here either does arithmetic on numbers you type, or reads public data off a blockchain. Not one of them asks you to connect a wallet, sign a message or approve anything, because a site that teaches you to be careful about signature prompts has no business adding one of its own.
That also means there is nothing here worth stealing. No accounts, no stored positions, no email list. Close the tab and it is gone.
Not sure which number actually matters?
Most people size positions by feel and find out what that costs later. We can walk through your real holdings, set the risk per trade, and check what you already have open.
