When a new signal is issued, it contains information: asset, trading price, expiration time, and direction. Some services provide additional information, such as when a signal was issued, but this is not so important. For example, the signal contains the information: 'Call (Up) GBPJPY 154.746 19:45:00'. It states that at 19:45:00 the price of the GBPJPY asset will be above 154.746. If so, the system will write won. Otherwise, a loss. If you open a 'Call' or 'Up' trade from any price below 154.746 at any time during the period when the signal was active and close it exactly at 19:45:00, you also win.
