Welcome here Chris !
chrisdr:How should I interpret the signal
That's up to you ;) There are thousands of different ways to do it and they all might be profitable. There aren't any sure fire system.
A possible entry point would be a macd crossover on a 15 min chart the next day. And you could exit when the system tells you to exit.
That being said, I don't have a lot of faith in metastock's expert systems. There are great for learning but they shouldn't be used "as is" in live trading.
