Simple Alerts

Hey all,
Am hoping someone either knows of some floating around (have searched but having a hard time) or knows how to create a simple alert for:

RSI: alert when RSI crosses above 50 or crosses below 50
MACD: alert when macd crosses above 0 or crosses below 0


Thanks for any help.

hope this helps.

Thank you, that's probably as good as I am gonna get without finding a nice little wizard or something to do it.
I appreciate you forwarding that to me.
