Help: Multiple indicator crossover alerrt/email

I am looking for an indicator that will allow me to send an email alert when multiple crosses occur:

- MACD with 1 setting
- MACD with 2nd setting
- STOCH with 1 setting
- STOCH with 2nd setting
etc....

How can I put all of these in one indicator?
I have seen the single indicators that alerts when crosses only one item- like MA, MACD, STOCH etc.. BUT. HOw can I combine multiple in one.

If anyone knows any thing similar exist maybe then I can understand and modify. But I am not sure where and how to start.

Thanks in advance
