FAQ
Does this connect to Polymarket or my wallet?
No. This is a local calculator only. It does not place orders, read balances, or connect to a wallet.
How is break-even calculated?
For a standard YES or NO share, your break-even price is your average buy price. Above that level you are in profit; below it you are in loss.
