Risk Disclaimer
Binary options trading carries a high risk of loss and is not suitable for every investor. The Masaniello method
implemented here is a position-sizing / stake-management calculator only — it does not predict trade outcomes,
does not guarantee profit, and is not financial or investment advice.
This tool runs entirely in your browser. No account, trade, or session data is ever sent to a server; everything
is stored locally via your browser's localStorage and is only ever visible to you, on this device,
in this browser.
The "projected final capital" shown during a session is an estimate that assumes your chosen average payout %
continues on every remaining trade at exactly the suggested stake. Real payouts vary trade to trade, so actual
results can and will differ.
