Need help on creating EA, any guides?

Any guides available out there? basically nt too sure if this is considered as a EA but i probably need some alarm to alert me. if possible, to sound off a custom sound.wav

For a simple start, any idea how would i write these?

I would like to be alerted by some alarm when stochastic hit above 80, or falls below 20 or when there is a crossover in region above 80 or below 20

a alert sound off when opening price is above ema(5,0,high) or below ema(5,0,low) at 15min chart

thanks in advance!

p.s any idea whats this annoying alarm sound that come out of nowhere while iam monitoring the chart on my mt4?

The only experience I have with creating an ea is through a program called “Expert Advisor Builder” Google it; the program is free and creates simple eas based on technical indicators. I found it difficult, however, to create anything more sophisticated than a moving average crossover system, which is demonstrated in the tutorial. As for an alarm, the basic setup for an expert advisor on metatrader four has a function “ask manual confirmation”, this may give an alarm, I’m not sure. I hope this helps, some people claim expert advisor builder is great; I’ve never put much time into figuring it out.
