When a discrete event message enters its discrete input port, the Stopwatch block evaluates its StopTime formula (using the Formula Builder) to determine the stop time in milliseconds. After the specified stop time, the block sends a discrete event message through its output port.
Example The Stopwatch block is triggered when it receives a discrete event message from a fill. The Stopwatch block formula is set to 1000, which causes the block to wait one second before forwarding the discrete event message to the DiscreteOrder block to submit the exit order.
Each time the block receives an input, it resets and restarts the timer. For example, suppose a Stopwatch block with a 5000ms timer is triggered by an incoming message. After five seconds, it sends out a discrete event message. However, if a second input message enters the block after only three seconds (3000ms), the Stopwatch block restarts its internal timer. In this case, the Stopwatch block will it send its first output message after eight seconds.
To customize the block, update the Block Properties.
