query for a beginner's tool

[greendesert]

I am not new to trading ie. not new to making huge losses but want to change my ways.

I wish to step into the world of technical analysis but it looks so jumbled.
Does Aget, metastock, amibroker perform the same work ? I have managed to get hold of latest amibroker. Is anyone better than other or is it a matter of
choice ? Is there any guide online as to how to use it comprehensively ? Any word of advice would be appreciated.

If only I was as good at these tools as I am with computer
maybe with time, right now seem to be lost

thanks !
