Binance cuts SignalPlus access after security warning, urges users to check accounts

Binance has severed trading connections with third-party options platform SignalPlus after a security warning, though the exchange said its own systems were unaffected and described the move as precautionary. The cut affects users who trade options through SignalPlus via Binance, and the exchange urged customers to review their accounts and open positions. Binance did not disclose the size of affected volumes or the number of impacted users. The delinking matters because it temporarily narrows options-trading routes for Binance users and highlights counterparty and integration risk at third-party venues. Traders should watch for SignalPlus's explanation of the warning and for Binance to restore connectivity once the issue is resolved.
