Normally signals are issued after market close to be traded at the open the next day. There is a model component that detects a bottoming pattern. In this case it is usually better to buy at the close the same day.
Of course I don’t know the close ahead of time. I set my trade to execute 5 seconds before the close if it is triggered. A few minutes before that or the open the next day is OK too.
After this, I will publish the trade trigger ahead of time on the signal page when this signal is in play.
