Fast answer
Coinbase signal checks start with order details.
Before treating a Coinbase-related signal as useful, check the exact market pair, entry type, stop-limit or limit instruction, timing window, update rule, and whether the provider preserves the original call after the trade closes.
An exchange name does not verify a third-party signal provider.
Execution checks
What to inspect in a Coinbase signal.
Order type
Market, limit, stop-limit, and bracket-style instructions can create different fill and miss risks.
Pair and venue
The signal should name the pair and whether the alert assumes Advanced Trade, spot execution, or another path.
Trigger and limit
For stop-limit logic, the trigger and limit prices should be visible before the move happens.
Final status
The provider should record fills, missed entries, cancellations, stopped trades, and open remainder status.
Official context
Order type language can hide execution risk.
Coinbase's order-type help explains that stop-limit orders use a stop price and a limit price. That distinction matters because a signal can trigger without guaranteeing the same result for every follower.
Review standard
Judge the provider record, not the venue label.
A reviewable Coinbase signal record includes the original alert, pair, order type, entry window, stop or invalidation, update trail, final outcome label, and notes for signals that never filled.
